Tullow Swings and Misses off Guyana Tullow Oil has come away empty with its Beebei-Potaro exploration well, drilled in the Kanuku license, offshore Guyana. According to the company, the well encountered good quality reservoir in the primary and secondary targets but both targets were water-bearing. Noble jackup Regina Allen drilled the well to a total depth of 4325 m in 71 m of water. The well has been plugged and abandoned. Tullow will integrate the well results into its regional subsurface models and work with its joint venture partners before deciding on next steps. Repsol is the operator of the Kanuku license with a 37.5% working interest. Tullow holds 37.5% with TOQAP—a joint venture between TotalEnergies and Qatar Petroleum—holding 25%. Tullow previously said it would limit capital exposure in Guyana. The company holds a 60% interest in the Orinduik block, its other licensed area in Guyana, with partners including TotalEnergies and Eco Atlantic Oil & Gas. Oxy Brings Horn Mountain West Online in GOM Occidental has successfully turned the taps on its Horn Mountain West subsea field in the Mississippi Canyon area of the Gulf of Mexico (GOM). The field is in about 5,400 ft of water. The $250-million project comprises a pair of wells tied back to the existing Horn Mountain spar in Block 126 via a 3½-mile dual flowline. According to Oxy, the project came in on budget and 3 months ahead of schedule. It is expected to eventually add approximately 30,000 BOPD. Horn Mountain initially came on stream in late 2002. Hess Strikes Miocene-Aged Oil at Huron in GOM Hess made an oil discovery with a well at its Huron prospect in the Green Canyon area of the deepwater GOM. The well, drilled in Block 69 to a target depth of 28,900 ft by Transocean drillship Deepwater Asgard, struck high-quality, oil-bearing Miocene-aged reservoirs and established the existence of a working petroleum system. An up-dip sidetrack to the initial probe is planned. Gregory Hill, Hess’ chief operating officer, told investors in July that … “as a result of what we’re seeing at Huron we see additional prospectivity in that northern Green Canyon area, and we have a very competitive leasehold position there.” The company had stated previously that its position in the northern Green Canyon area has a high potential for multiple, high-return hub-class Miocene opportunities. Hess operates Huron with a 40% interest. Partners Chevron and Shell each hold 30% stakes. Hess struck a deal with both Chevron and Shell to farm into the prospect in February 2022. The Huron well marks Hess’ return to exploration drilling in the deepwater GOM for the first time in around 2 years. Wintershall Dea Turns the Taps at Nova Wintershall Dea started production from the Nova oil field in the Norwegian North Sea. The field comprises two subsea templates, one with three oil producers and one with three water injectors, tied back to the Gjøa platform. The expected recoverable gross reserves from the field are estimated at 90 million BOE, of which the majority will be oil. The operator said the completion of Nova emphasizes its strength as one of the largest subsea operators on the Norwegian Continental Shelf. “With the startup of the major project Nova, Wintershall Dea is now operating three subsea production fields in Norway,” said Hugo Dijkgraaf, member of the executive board and chief technology officer. The Dvalin field and the partner-operated Njord Future project, in which Wintershall Dea holds a 50% share, are planned to come on stream later this year. The company also operates recent discoveries like Dvalin North, planned for PDO hand-in (Plan for Development and Operations) by the end of 2022, and several other discoveries which could be developed in the future. Wintershall Dea is a partner in the Aker BP-operated Storjo discovery in the Norwegian Sea. Wintershall Dea operates the Nova field with a 45% stake, of which it plans to transfer 6% to OKEA in Q4 this year; Sval Energi holds 45%, Pandion Energy Norge, 10%. Eni Touts Potential 3.5-Tcf Gas Find With First Offshore Abu Dhabi Well Eni believes it has discovered an additional 1.0 to 1.5 Tcf of raw gas in place, in a deeper zone, in its first exploration well drilled in Offshore Block 2 Abu Dhabi. The discovery follows an initial finding in a shallower zone of the same well, aggregating to a total gas in place of up to 3.5 Tcf. The Italian operator said gas-bearing reservoirs were tested with excellent flow rates and fast-track development options are currently under evaluation. Eni, operator, holds a 70% stake in Block 2; PTTEP holds the remaining 30%. Eni has been present in Abu Dhabi since 2018. It operates three exploration concessions and participates with ADNOC in three offshore development and production concessions: Lower Zakum (5%), Umm Shaif and Nasr (10%), and Ghasha (25%). Petrobras Makes Gas Discovery in Colombia Petrobras confirmed the discovery of natural gas accumulation in the Uchuva-1 exploratory well drilled in the deep waters 32 km off the coast of Colombia. The discovery is about 76 km from the city of Santa Marta in a water depth of approximately 830 m. The well was drilled in the Tayrona block, with operator Petrobras (44.44%) in partnership with Ecopetrol, who holds the remaining stake. The consortium will continue its activities in the block to assess the dimensions of the new gas accumulation. CNOOC Successfully Tests Offshore Shale Well China’s CNOOC Ltd. tested commercial flows of oil and gas from an offshore shale exploration well in the South China Sea, marking the first successfully drilled shale oil well offshore China, state media reported in early August. Exploration well Weiye-1, drilled at the southwestern trough of Beibuwan basin, tested daily production of 126 bbl of oil and 1589 m3 of natural gas. CNOOC estimated that the shale oil resources in the entire basin are about 8.8 billion bbl, suggesting good exploration prospects. With the Chinese government stressing added volumes for its domestic energy supply security, national oil companies are making greater efforts to tap shale deposits despite being tougher to drill and more expensive. As of late 2021, China produced only 35,000 B/D of shale oil, mostly in the onshore northern Ordos basin and northwestern Jungar basin. Eni Strikes Oil With Baleine East Well in Côte d’Ivoire Eni has encountered oil with its Baleine East 1X well, the first exploration well in block CI-802 and second discovery on the Baleine structure offshore Côte d’Ivoire. The results have prompted a 25% increase in the oil and gas volumes in place, which are now estimated at 2.5 billion bbl of oil and 3.3 Tcf of associated gas. The well was drilled in the block operated by Eni (90%), together with its partner Petroci Holding (10%), using the drillship Saipem 12000. The final depth reached was 3165 m measured depth, in a water depth of about 1150 m. Baleine East 1X is located about 5 km east of the Baleine 1X discovery well in the adjacent block CI-101 and represents the first commercial discovery in the CI-802 block, confirming the extension of the Baleine field. The well confirmed the presence of a continuous oil column of about 48 m in reservoir rocks with good properties. From the vertical borehole, a horizontal drain of 850 m in length was subsequently drilled into the reservoir to perform a production test that confirmed potential production of at least 12,000 BOPD from the Baleine East 1X well. A third well will be drilled to ensure the accelerated startup of production and confirmation of first oil in the first half of 2023. In addition to blocks CI-101 and CI-802, Eni owns interests in five other blocks in the Ivorian deep water: CI-205, CI-501, CI-504, CI-401, and CI-801, all with the same partner, Petroci Holding. Neptune Energy Kicks Off Ofelia Exploration Well Neptune Energy began drilling operations on the Ofelia exploration well in the Norwegian sector of the North Sea. The well, 35/6-3 S, is being drilled by the Odfjell Drilling-operated semisubmersible Deepsea Yantai. The prospect is located 13 km north of the Gjøa field within the Neptune-operated PL929 License. If commercial, Ofelia could be tied back to the Neptune-operated Gjøa platform and produce at less than half the average carbon intensity of Norwegian Continental Shelf fields, according to the company. Neptune said it could potentially be developed in parallel with Hamlet (PL153). Ofelia is positioned in one of Neptune’s core areas and close to existing infrastructure. The reservoir target is the Lower Cretaceous Agat Formation and is expected to be reached at a depth of approximately 2570 m. The drilling program comprises a main bore (35/6-3 S) with an optional sidetrack (35/6-3 A) based on the outcome of the exploration well. Neptune Energy operates Ofelia with a 40% working interest. Partners are Wintershall Dea (20%), Aker BP (10%), Pandion Energy (20%), and DNO (10%). Partners Continue Successful Drilling in Algerian Desert Eni and partner Sonatrach revealed a further discovery in the Zemlet el Arbi concession, located in the Berkine North Basin in the Algerian desert. The Rhourde Oulad Djemaa Ouest-1 (RODW-1) exploration well, in the Sif Fatima II research perimeter, is the third well in the exploration drilling campaign. It led to a discovery of oil and associated gas in the Triassic sandstones of the Tagi reservoir. During its production test, the well produced 1,300 BOPD and about 2 MMcf/D of associated gas. The RODW-1 discovery comes after the significant discovery of HDLE-1, announced in March 2022, and the successful second appraisal well HDLS-1 in the adjacent Sif Fatima II. Because of their proximity to existing BRN/ROD facilities, the development of these discoveries will be fast-tracked. The Zemlet el Arbi concession is operated by a joint venture between Eni (49%) and Sonatrach (51%). The discovery is part of the new exploration campaign which will include the drilling of five wells in the Berkine North Basin.

Increasing demands for gas storage capacity encouraged Polish Gas and Oil Company (PGNiG) to make use of salt deposits located in the north-eastern part of Poland, in the area bordering on the Gulf of Gdańsk (South Baltic Sea), and create underground gas stores. A complex of 10 chambers (250x106 m3) was designed to be built at a depth of 800-1600 m. The construction site is located about 4 km away from the sea coast. The drilling of boreholes and diluting of salt rock was proposed as a method of creating the chambers. Owing to ecological reasons, maximum discharge of brine is limited to 300 m3/h with the max. saturation of 250 kg/m3. The Puck Bay is a shallow water body with wind-driven currents and negligible tides. The main difficulty of the investment lay in the effective spreading of brine in the Puck Bay in accordance with all requirements that apply to regions protected by NATURA 2000. The most important restriction was the permitted excess salinity, defined as 0.5 PSU over the natural salinity in the Puck Bay. The location of brine discharge, number and diameters of nozzles, as well as consequences of brine discharge on the Puck Bay water, had been analyzed before the permission to install the system of diffusers was granted by the regional administration. The installation consists of a system of 16 heads spaced every 45 m, each of them equipped with 3 nozzles of 8 mm diameter.

Sonadrill Lands Contract for Drillship Seadrill confirmed a new contract has been secured by Sonadrill Holding, Seadrill’s 50:50 joint venture with an affiliate of Sonangol for the drillship West Gemini. Sonadrill has secured a 10‑well contract with options for up to eight additional wells in Angola for an unknown operator. Total contract value for the firm portion of the deal is expected to be around $161 million, with further revenue potential from a performance bonus. The rig is expected to begin the work in the fourth quarter of this year with a firm term of about 18 months, in direct continuation of the West Gemini’s existing contract. The West Gemini is the third drillship to be bareboat chartered into Sonadrill, along with two Sonangol‑owned units, the Sonangol Quenguela and Sonangol Libongos. Seadrill will manage and operate the units on behalf of Sonadrill. Together, the three units position the Seadrill joint venture as an active rig operator in Angola, furthering the goal of building an ultradeepwater franchise in the Golden Triangle and driving efficiencies from rig clustering in the region. Petrobras Receives TotalEnergies, Shell Payments for Atapu TotalEnergies and Shell have formalized payments to Petrobras for separate, minority stakes in the pre‑salt Atapu field in the Santos Basin. TotalEnergies paid $4.7 billion reais ($940 million) while Shell paid closer to $1.1 billion. The Atapu block was acquired by the consortium comprising Petrobras (52.5%), Shell (25%), and TotalEnergies (22.5%) in the Second Bidding Round for the Transfer of Rights auction held 17 December 2021. The payments are compensation for monies spent thus far by Petrobras, which was granted contractual rights to produce 550 million BOE from Atapu in 2010. The partners will now work together to produce additional volumes from the field. Production at Atapu started in June 2020 via the P-70 FPSO. The unit is in about 2000 m of water and has the capacity to produce 150,000 BOED. CNOOC Brings New Bohai Sea Discoveries On Stream CNOOC Limited has kicked off production from its Luda 5‑2 oil field North Phase I project and Kenli 6‑1 oil field 4‑1 Block development project. Luda 5‑2 is in the Liaodong Bay of Bohai Sea, with average water depth of about 32 m and utilizes a thermal recovery wellhead platform and production platform tied into the Suizhong 36‑1 oil field. A total of 28 development wells are planned, including 26 production wells and two water‑source wells. The project is expected to reach its peak production of 8,200 B/D of oil in 2024. Kenli 6‑1 is in the south of Bohai Sea, with average water depth of about 17 m. The resource is being developed by a wellhead platform in addition to fully utilizing the existing processing facilities of the Bozhong 34‑9 oil field. A total of 12 development wells are planned, including seven production wells and five water‑injection wells. The field is expected to reach its peak production of 4,000 B/D of oil later this year. CNOOC Limited is operator and sole owner of the Luda 5‑2 oil field North and the Kenli 6‑1 oil field 4‑1 Block. Stabroek Block Bounty Off Guyana Gets Bigger The partners in the prolific Stabroek Block have again increased the gross discovered recoverable resource estimate for the area offshore Guyana. The owners now believe they have discovered reserves of at least 11 billion BOE, up from the previous estimate of more than 10 billion BOE. The updated resource estimate includes three new discoveries on the block at Barreleye, Lukanani, and Patwa in addition to the Fangtooth and Lau Lau discoveries announced earlier this year. The Barreleye‑1 well encountered approximately 70 m of hydrocarbon‑bearing sandstone reservoirs of which 16 m is high‑quality oil‑bearing. The well was drilled in 1170 m of water and is located 32 km southeast of the Liza field. The Lukanani‑1 well encountered 35 m of hydrocarbon‑bearing sandstone reservoirs of which approximately 23 m is high‑quality oil‑ bearing. The well was drilled in water depth of 1240 m and is in the southeastern part of the block, approximately 3 km west of the Pluma discovery. The Patwa‑1 well encountered 33 m of hydrocarbon‑bearing sandstone reservoirs. The well was drilled in 1925 m of water and is located approximately 5 km northwest of the Cataback‑1 discovery. “These new discoveries further demonstrate the extraordinary resource density of the Stabroek Block and will underpin our queue of future development opportunities,” said John Hess, chief executive of Hess and a partner in Stabroek. The co‑venturers have sanctioned four developments to date on Stabroek with both Liza and Liza Phase 2 on stream. The third planned development at Payara is ahead of schedule and is now expected to come on line in late 2023; it will utilize the Prosperity FPSO with a production capacity of 220,000 BOPD. The fourth development, Yellowtail, is expected to come on line in 2025, utilizing the ONE GUYANA FPSO with a production capacity of 250,000 BOPD of oil. At least six FPSOs with a production capacity of more than 1 million gross BOPD are expected to be on line on the Stabroek Block in 2027, with the potential for up to ten FPSOs to develop gross discovered recoverable resources. The Stabroek Block is 6.6 million acres. ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45% interest; Hess Guyana Exploration holds 30% interest; and CNOOC Petroleum Guyana Limited holds 25%. ConocoPhillips Gets Ekofisk License Extension Norway’s Ministry of Petroleum and Energy (MPE) has extended production licenses in the Greater Ekofisk Area from 2028 to 2048 with ConocoPhillips as operator. The company said the license extension provides long‑term operations and resource management aligned with the company’s long‑term perspective on the Norwegian continental shelf. Fields on the shelf are required to operate with a valid production license where the operator and licensees enter into an agreement with the authorities, including relevant field activities. The authorities may require commitments, leading to increased oil recovery. The existing production licenses 018, 018 B, and 275 in the Greater Ekofisk Area were set to expire on 31 December 2028; however, the MPE approved an extension through 2048. The new terms provide a potential for extending Ekofisk’s lifetime to nearly 80 years. The license partners are ConocoPhillips (operator, 35.11%), TotalEnergies EP Norge (39.896%), Vår Energi (12.388%), Equinor (7.604%), and Petoro (5%). BHP’s Wasabi Disappoints in US GOM Australian operator BHP encountered noncommercial hydrocarbons with its Wasabi‑2 well in the US Gulf of Mexico. BHP said the well in Green Canyon Block 124 was plugged and abandoned following the disappointing results. “This completes the Wasabi exploration program, with results under evaluation to determine next steps,” the company said. The well was targeting oil in an early Miocene reservoir. Transocean drillship Deepwater Invictus spudded the well in 764 m of water in November 2021. The previous Wasabi‑1 well had a mechanical problem and was plugged and abandoned 4 days earlier, prior to reaching its prospective targets. BHP operates Wasabi with a 75% interest. Lukoil Says Titonskaya Holds 150 Million BOE Russia’s Lukoil believes it has discovered around 150 million BOE following analysis of the two wells it drilled at the Titonskaya structure on the Caspian Sea shelf. Work is now underway to refine the seismic models of productive deposits and study deep samples of formation fluids. The results of the assessment will be submitted to the State Reserves Commission of the Russian Federation. The structure is in the central part of the Caspian Sea, not far from the Khazri field. Lukoil drilled the first well at the Titonskaya structure in 2020 and announced the new discovery in April 2021. According to that assessment, the probable geological resources of the Titonskaya are 130.4 million tons. In 2021, drilling of the second prospecting and appraisal well began to identify oil and gas deposits in the terrigenous‑carbonate deposits of the Jurassic‑ Cretaceous age. The well was drilled using the Neptune jackup drilling rig. The new find at Titonskaya will likely be tied into Khazri infrastructure. Petrobras’ Roncador IOR Project Comes On Line Petrobras has successfully started production from the first two wells of the improved oil recovery (IOR) project at the Roncador field in the Campos Basin offshore Brazil. The two wells are the first of a series of IOR wells to reach production. Startup is almost 5 months ahead of schedule and at half of the planned cost, according to partner Equinor. The wells will add a combined 20,000 BOED to Roncador, bringing daily production to around 150,000 bbl and reducing the carbon intensity (emissions per barrel produced) of the field. Through this first IOR project, the partnership will drill 18 wells that are expected to provide additional recoverable resources of 160 million bbl. Improvements in well design and the partners’ combined technological experience are the main drivers behind the 50% cost reduction across the first six wells, including the two in production. Roncador is Brazil’s fifth‑largest producing asset and has been in production since 1999. Petrobras operates the field and holds a 75% stake. In 2018, Equinor entered the project as a strategic partner with the remaining 25% interest. In addition to the planned 18 IOR wells, the partnership believes it can further improve recovery and aims to increase recoverable resources by a total of 1 billion BOE. The field has more than 10 billion BOE in place under a license lasting until 2052. The strategic alliance agreement also includes an energy‑efficiency and CO2‑emissions‑reduction program for Roncador. Gazania-1 To Spud Off South Africa Africa Energy will move ahead with its planned Gazania‑1 wildcat well offshore South Africa after securing partner Eco Atlantic’s $20 million in capital requirements for its portion of the probe. The well will be drilled in Block 2B. Island Drilling semisubmersible Island Innovator has been contracted for the work and is expected to mobilize from its current location in the North Sea for the 45‑day trip to South Africa. The Block 2B joint venture plans to spud the well by October with drilling expected to last 30 days, including a full set of logs if the well is successful. The block has significant contingent and prospective resources in relatively shallow water and contains the A‑J1 discovery that flowed light sweet crude oil to surface. Gazania‑1 will target two large prospects 7 km updip from A‑J1 in the same region as the recent Venus and Graff discoveries. Block 2B is located offshore South Africa in the Orange Basin where both TotalEnergies and Shell recently announced significant oil and gas discoveries offshore Namibia. The block covers 3062 km2 approximately 25 km off the west coast of South Africa near the border with Namibia in water depths ranging from 50 m to 200 m. The Southern Oil Exploration Corp. (Soekor) discovered and tested oil on Block 2B in 1988 with the A‑J1 borehole, which intersected thick reservoir sandstones between 2985 m and 3350 m. The well flowed 191 B/D of 36 °API oil from a 10‑m sandstone interval at around 3250 m. Africa Energy has a 27.5% interest in Block 2B offshore South Africa. The block is operated by a subsidiary of Eco Atlantic which holds a 50% interest. A subsidiary of Panoro Energy holds a 12.5% stake, and Crown Energy AB indirectly holds the remaining 10%. Brazil Grants New Exploration Blocks Brazil’s National Agency of Petroleum, Natural Gas, and Biofuels (ANP) has granted 59 exploratory blocks of oil and natural gas to 13 companies, including Shell, TotalEnergies, and 3R Petroleum. The awards were part of a permanent bid offer round held in Rio de Janiero in April. The auction totaled 422.4 million reais in signature bonuses with leases granted in six Brazilian states: Rio Grande do Norte, Alagoas, Bahia, Espírito Santo, Santa Catarina, and Paraná. The awards will result in investments of 406.3 million reais in the exploratory phase of the contracts. Shell Brazil (70%) was granted six blocks in the Santos Basin in a consortium with the Colombian Ecopetrol (30%). The blocks leases were SM‑1599, SM‑1601, SM‑1713, SM‑1817, SM‑1908, and SM‑1910. TotalEnergies won two areas in the same basin while Brazilian company 3R Petroleum received six areas in the Potiguar Basin. Petro‑Victory was also awarded 19 new blocks in Potiguar, increasing its holdings in Brazil to 38 blocks (37 in Potiguar). The new blocks are nearby Petro‑Victory infrastructure at the Andorinha, Alto Alegre, and Trapia oil fields. Eni Finds More Oil in Egypt’s Western Desert Eni struck new oil and gas reserves with a trio of discoveries in the Meleiha concessions of Egypt’s Western Desert. The finds have already been tied into existing infrastructure in the region and have added around 8,500 BOED to overall production from the area. The operator drilled the Nada E Deep 1X well, which encountered 60 m of net hydrocarbon pay in the Cretaceous‑Jurassic Alam El Bueib and Khatatba formations Meleiha SE Deep 1X well, which found 30 m of net hydrocarbon pay in the Cretaceous‑Jurassic sands of the Matruh Khatatba formations, and the Emry Deep 21 well, which encountered 35 m of net hydrocarbon pay in the massive cretaceous sandstones of Alam El Bueib. The results, added to the discoveries of 2021 for a total of eight exploration wells, give Eni a 75% success rate in the region. The company added that additional exploration activities in the concession are ongoing with “promising indications.” With these discoveries, Eni, through AGIBA, a joint venture between Eni and EGPC, continues to pursue its near‑field strategy in the mature basin of the Western Desert, aimed at maximizing production by containing development costs and minimizing time to market. Eni is planning a new high‑resolution 3D seismic survey in the Meleiha concession this year to investigate the gas potential of the area. Eni is currently the leading producer in Egypt with an equity production of around 360,000 BOED.

China Shale-Gas Field Sets Production Record Sinopec recorded China’s highest daily output of shale gas at 20.62 million cubic meters (Mcm) at its Fuling shale-gas field in Chongqing, China, a key gas source for the Sichuan-East gas pipeline. The first major commercial shale-gas project in China, Fuling has continuously broken records for the shortest gasfield drilling cycle while significantly increasing the drilling of high-quality reservoirs covering more than 3 million m, according to Sinopec. Gasfield production construction was also expanded to raise production capacity. The company said the field maintains a daily output of 20 Mcm, producing an estimated 6.7 Bcm per year. Apache and Total Plan Suriname Appraisals Apache filed appraisal plans for its Maka and Sapakara oil discoveries in block 58 offshore Suriname. The company said another submission is expected for Kwaskwasi, the largest find in the block, by the end of the year. Operations continue for Keskesi, the fourth exploration target. There are plans to drill a fifth prospect at Bonboni in the North-Central portion of the concession. Partner company Total is assuming operatorship of the block ahead of next year’s campaigns. BP Emerges as Sole Bid for Offshore Canada Parcels BP was the only operator to place a bid in the Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB) Call for Bids NL20-CFB01, which offered 17 parcels (4,170,509 hectares) in the eastern Newfoundland region. The successful bid was for Parcel 9 (covering 264,500 hectares) for $27 million in work commitments from BP Canada Energy Group. Subject to BP satisfying specified requirements and receiving government approval, the exploration license will be issued in January 2021. No bids were received for the remaining 16 parcels, which may be reposted in a future Call for Bids. Criteria for selecting a winning bid is the total amount the bidder commits to spend on exploration of the parcel during the first period of a 9-year license, with a minimum acceptable bid of $10 million in work commitments for each parcel. Beach Energy To Drill Otway Basin Well Beach Energy plans to drill at its Artisan-1 well about 32 km offshore Victoria, Australia, in the Otway basin, before the end of 2021. The well, located on Block Vic/P43, was to be spudded in 1H 2020 but was delayed due to COVID-19. The timeframe for drilling was confirmed by the National Offshore Petroleum Safety and Environmental Management Authority, which also said Beach is keeping open the option to suspend the well and develop it, pending reservoir analysis. Anchors, mooring chains, and surface buoys have already been laid for the well, which is in a water depth of approximately 71 m. The well is expected to take approximately 35–55 days to drill, depending on the final work program and potential operational delays. Diamond Offshore’s semisubmersible Ocean Onyx was contracted for the drilling program. Artisan is the first of Beach’s planned multiwell campaigns, which also include development wells at the Geographe and Thylacine fields. Hess Completes Sale of Interest in Gulf of Mexico Field Hess completed the sale of its 28% working interest in the Shenzi Field in the deepwater Gulf of Mexico (GOM) to BHP, the field’s operator, for $505 million. Shenzi is a six-lease development structured as a joint ownership: BHP (operator, 44%), Hess (28%), and Repsol (28%). The acquisition would bring BHP’s working interest to 72%, adding approximately 11,000 BOE/D of production (90% oil). The sale is expected to close by December 2020. Hess CEO John Hess said proceeds from the sale will help fund the company’s investment in Guyana. Greenland Opens New Offshore Areas Greenland opened three new offshore areas for application of oil and gas exploitation licenses off West Greenland. The areas are Baffin Bay, Disko West, and Davis Strait. The country also said it is working on an oil strategy to reduce geological uncertainty by offering an investment package to companies that engage in its Open Door Procedures. The procedures are a first-mover advantage to remove national oil company Nunaoil, as a carried partner, reducing turnover and surplus royalties. It is estimated to reduce the government take by 51.3% to 40.6%. Shell and Impact Oil & Gas Agree to South Africa Farmout Africa Oil announced Impact Oil & Gas entered into two agreements for exploration areas offshore South Africa. The company has a 31.10% share-holding in Impact, a privately owned exploration company. Impact entered into an agreement with BG International, a Shell subsidiary, for the farm-out of a 50% working interest and operatorship in the Transkei and Algoa exploration rights. Shell was also granted the option to acquire an additional 5% working interest should the joint venture (JV) elect to move into the third renewal period, expected in 2024. Algoa is located in the South Outeniqua Basin, east of Block 11B/12B, containing the Brulpadda gas condensate discovery and where Total recently discovered gas condensate. The Transkei block is northeast of Algoa in the Natal Trough Basin where Impact has identified highly material prospectivity associated with several large submarine fan bodies, which the JV will explore with 3D seismic data and then potential exploratory drilling. Impact and Shell plan to acquire over 6,000 km² of 3D seismic data during the first available seismic window following completion of the transaction. This window is expected to be in the Q1 2022. After the closing of the deal, Shell will hold a 50% interest as the operator and Impact will hold 50%. Impact also entered into an agreement with Silver Wave Energy for the farm-in of a 90% working interest and operatorship of Area 2, offshore South Africa. East and adjacent to Impact’s Transkei and Algoa blocks, Area 2 complements Impact’s existing position by extending the entire length of the ultradeepwater part of the Transkei margin. Together, the Transkei and Algoa Blocks and Area 2 cover over 124,000 km2. Area 2 has been opened by the Brulpadda and Luiperd discoveries in the Outeniqua Basin and will be further tested during 2021 by the well on the giant Venus prospect in ultradeepwater Namibia, where Impact is a partner. Impact believes there is good evidence for this Southern African Aptian play to have a common world-class Lower Cretaceous source rock, similar excellent-quality Apto-Albian reservoir sands, and a geological setting suitable for the formation of large stratigraphic traps. Following completion of the farm-in, Impact will hold 90% interest and serve as the operator; Silver Wave will hold 10%. Petronas Awards Sarawak Contract to Seismic Consortium The seismic consortium comprising PGS, TGS, and WesternGeco was awarded a multiyear contract by Petronas to acquire and process up to 105,000 km2 of multisensor, multiclient 3D data in the Sarawak Basin, offshore Malaysia. The contract award follows an ongoing campaign by the consortium in the Sabah offshore region, awarded in 2016, in which over 50,000 km2 of high-quality 3D seismic data have been acquired and licensed to the oil and gas industry to support Malaysia license round and exploration activity. The Sarawak award will allow for a multiphase program to promote exploration efforts in the prolific Sarawak East Natuna Basin (Deepwater North Luconia and West Luconia Province). The consortium is planning the initial phases and is engaging with the oil and gas industry to secure prefunding ahead of planned acquisition, covering both open blocks and areas of existing farm-in opportunities. Total Discovers Second Gas Condensate in South Africa Total made a significant second gas condensate discovery on the Luiperd prospect, located on Block 11B/12B in the Outeniqua Basin, 175 km off the southern coast of South Africa. The discovery follows the adjacent play-opening Brulpadda discovery in 2019. The Luiperd-1X well was drilled to a total depth of about 3,400 m and encountered 73 m of net gas condensate pay in well-developed, good-quality Lower Cretaceous reservoirs. Following a coring and logging program, the well will be tested to assess the dynamic reservoir characteristics and deliverability. The Block 11B/12B covers an area of 19,000 km2, with water depths ranging from 200 to 1800 m. It is operated by Total with a 45% working interest, alongside Qatar Petroleum (25%), CNR International (20%), and Main Street, a South African consortium (10%). The Luiperd prospect is the second to be drilled in a series of five large submarine fan prospects with direct hydrocarbon indicators defined utilizing 2D and 3D seismic data.

It is tied back to the Ha’py and Tuart field ‎development via a new 50-km pipeline and connected to existing subsea ‎utilities via a 50-km umbilical. ‎BP holds 100% equity in the North Damietta offshore concession in the East Nile Delta. ‎Gas production from the field is directed to Egypt’s national grid.

Shell Discovers More Oil Off Namibia Shell announced its oil discovery off Namibia in January and was “very encouraged by the early results” from the Graff-1 exploration well in the country’s Orange Basin, which “established a working petroleum system and the presence of light oil.” Researchers at Wood Mackenzie believe the find could hold upward of 700 million BOE. Shell is currently drilling a second well at La Rona, an aggressive stepout which is likely to be appraising the discovery prior to confirmation of a potential commercial development. Shell operates the Graff find with a 45% interest. Partners in the discovery are QatarEnergy (45%) and NAMCOR (10%). Less than a month after Graff was announced, TotalEnergies reported that it had made a significant discovery of light oil with associated gas on the Venus prospect, in Block 2913B in the Orange Basin. The Venus 1-X well encountered around 84 m of net oil pay in a Lower Cretaceous reservoir. No resource estimates have been officially released. First Oil Achieved at King’s Quay in the GOM Murphy Oil has achieved first oil from the Khaleesi, Mormont, and Samurai field development project in the deepwater Gulf of Mexico (GOM). The field trio is being developed subsea and tied back to the Murphy-operated King’s Quay floating production system (FPS), designed to process 85,000 B/D of oil and 100 MMcf/D of natural gas. The project comprises the Khaleesi/Mormont fields in Green Canyon Blocks 389 and 478, respectively, and the Samurai field, located in Green Canyon Block 432. Completions operations are ongoing for the remaining five wells in the seven-well project. Murphy operates the King’s Quay FPS and associated export lateral pipelines, which are owned 50% by an affiliate of Third Coast Infrastructure and 50% by entities managed by Ridgewood Energy, including ILX Holdings III LLC. Neptune Energy Ramps Up Gas Production From Duva Field Neptune Energy and its partners will be doubling gas production from the Duva field in the Norwegian sector of the North Sea, supporting increased supplies to the UK and Europe. The partnership has worked closely with the Norwegian authorities to identify measures to help meet gas demand in Europe. Gas production from the field was planned to increase by 6,500 BOE/D from the first half of April. Duva is a subsea installation with three oil producers and one gas producer, tied back to the Neptune Energy-operated Gjøa semisubmersible platform. The gas is transported by pipeline to the UK’s St Fergus gas terminal. Duva’s overall production currently stands at 30,000 BOE/D, of which 6,500 BOE/D is natural gas. Under the newly agreed measures, daily gas production will double to 13,000 BOE/D for an initial 4–8 months. Around 70% of Neptune Energy’s Norwegian production is gas, and the company is investigating opportunities to ramp up gas production from other fields within its portfolio. Duva license partners include operator Neptune Energy (30%), INPEX Idemitsu (30%), PGNiG Upstream Norway (30%), and Sval Energi (10%). New Oil Discovery Near Troll and Fram Area of the North Sea Equinor has once again discovered oil and gas close to the Troll and Fram area—this time with its Kveikje well. The find came on the operator’s 293 B production license. The company estimates the size of the discovery is between 25–50 million bbl of recoverable oil equivalent. Temporarily called Kveikje, this is the sixth discovery in this area since 2019. Up to more than 300 million BOE were proven in the five former discoveries. Equinor is considering the development as a tieback to the Troll B or C platform. There were several drilling targets in the exploration well. After Kveikje was discovered, drilling continued to the next target in the upper part of the Cretaceous stratigraphic sequence. Smaller deposits of petroleum were discovered but are considered noncommercial. The well has been permanently plugged and abandoned. The well was drilled by semisubmersible Deepsea Stavanger. Plans call for Equinor to drill another exploration well in this area this year. The 293 B license owners are Equinor (51%), DNO (29%), Idemitsu (10%), and Longboat Energy (10%). W&T Offshore Completes Bolt-On Acquisition in the GOM W&T Offshore has acquired the remaining working interests in the oil- and gas-producing properties at Ship Shoal 230, South Marsh Island 27/Vermilion 191, and South Marsh Island 73 fields for $17.5 million in cash. The initial interest was purchased earlier this year from an undisclosed private seller. The transaction had an effective date and closing date of 1 April and was paid using cash on hand. The deal adds internally estimated proved reserves of 1.4 million BOE (70% oil) and proved and probable, or 2P, reserves of 2 million BOE (75% oil) as of year-end 2021. The properties carry an estimated net sales rate of about 900 BOE/D (~80% oil). The acquisition also adds an average of 20% working interest in more than 50 gross producing wells currently operated by the company across three shallow-water fields and provides additional opportunities for future drilling. ExxonMobil Comes Up Empty on Cutthroat Prospect in Brazil Prospect partner Murphy Oil said it and operator ExxonMobil came away with disappointing results from their Cutthroat-1 exploration well in Block SEAL-M-428 in the Sergipe-Alagoas Basin offshore Brazil. While the presence of hydrocarbons was not found, the partner group said it will continue to integrate the exploration well data into its regional subsurface interpretation efforts to better understand the exploration potential of its deepwater blocks located in the basin. Cutthroat-1 was located nearly 90 km offshore Brazil and was drilled in 3094 m of water by the Seadrill West Saturn drillship. It is one of multiple prospects that the partner group has mapped in the basin. ExxonMobil is the operator and holds 50% working interest in nine offshore SEAL blocks that span more than 6800 km2. Enauta Energia and Murphy Oil each hold a 30% working interest. Eni Upgrades Ndungu Field Resources Off Angola Eni has boosted its reserves base for the Ndungu field in the West Hub of Block 15/06 following the results of an initial well. The Ndungu 2 appraisal well was drilled 5 km away from Ndungu 1 and encountered 40 m of net oil pay in the Lower Oligocene reservoirs with good petrophysical properties confirming the hydraulic communication with the discovery well. The preliminary data collected on Ndungu 2 allows Eni to boost the field resources to between 800 million and 1 billion BOE in place from the initial estimates of 250–300 million BOE following the discovery well. The upgrade makes Ndungu, together with Agogo, the largest accumulation discovered in Block 15/06 since the block award. The early production phase of Ndungu started in February through one producer well, and a second producer well is expected in the fourth quarter of 2022, maximizing the utilization of existing facilities in the West Hub. Ndungu field development will now be upgraded to reflect the increase of the resource base, following a phased approach to uncap the overall potential initially contributing to extend and increase the plateau of the Ngoma—a 100,000 B/D, zero-discharge and zero-process-flaring FPSO. Block 15/06 is operated by Eni Angola with a 36.84% share. Sonangol Pesquisa e Produção holds 36.84% and SSI Fifteen Ltd., 26.32%. ExxonMobil Strikes Gas Off Cyprus The Cyprus energy ministry confirmed a reservoir of high-quality gas was encountered by the ExxonMobil-led Glaucus-2 appraisal well. The drilling of the well was conducted in the area known as Block 10 in the Exclusive Economic Zone (EEZ) that has been challenged by Turkey. The ministry said that operations in the EEZ included production testing. “The consortium will proceed with a detailed analysis and evaluation of the data collected to more accurately determine the qualitative and quantitative characteristics of the reservoir, as well as potential development and commercialization of the discoveries,” the ministry said in a statement. Cyprus previously estimated gas resources in the reservoir of between 5 and 8 Tcf when the discovery from the Glaucus-1 well was announced in 2019. ExxonMobil and Block 10 partner Qatar Petroleum began drilling the Glaucus-2 well using drillship Stena Forth in December 2021. ExxonMobil is the operator and holds a 60% interest in Block 10. Qatar Petroleum International Upstream OPC holds the remaining 40% stake. Eni, Sonatrach Make Oil Hit in Algerian Desert Eni and Sonatrach made a significant oil and gas discovery in the Zemlet el Arbi concession located in the Berkine North Basin in the Algerian desert. The concession is operated by a joint venture between Eni (49%) and Sonatrach (51%). Preliminary estimates of the size of the discovery are around 140 million bbl of oil in place. The exploratory well that led to the discovery has been drilled on the HDLE exploration prospect, about 15 km from the processing facilities of Bir Rebaa North field. HDLE-1 discovered light oil in the Triassic sandstones of the Tagi formation confirming 26 m of net pay. During a production test, the well delivered 7,000 BOPD and 5 MMcf/D of associated gas. The HDLE-1 well is the first well of the new exploration campaign which will include the drilling of five wells in the Berkine North Basin. The discovery will be appraised by the followup HDLE-2 well to confirm the additional potential of the structure extending in the adjacent Sif Fatima 2 concession operated by an Eni-Sonatrach JV (50–50%). In parallel with the appraisal program, Eni and Sonatrach will perform studies and analyses to accelerate the production phase of the new discovery through a fast-tracked development with startup planned for the third quarter of 2022. Eni has been present in Algeria since 1981 where it operates several concessions. The company produces about 95,000 BOE/D from the country. Neptune Energy Confirms Hydrocarbons at Hamlet Neptune Energy struck hydrocarbons at its Hamlet exploration well in the Norwegian sector of the North Sea. The find is located within the Gjøa license (PL153). It has yet to be confirmed if commercial volumes of oil and gas are present. A contingent sidetrack may be drilled to further define the extent of the discovery. Located 58 km west of Florø, Norway, at a water depth of 358 m, Hamlet is within one of Neptune’s core areas and close to existing infrastructure. The Hamlet test was drilled by the Odjfell semisubmersible Deepsea Yantai. Partners in the find include operator Neptune Energy (30%), Petoro (30%), Wintershall Dea (28%), and OKEA (12%).

The case featured in this issue depicts a situation enmeshed in several organizational and systems problems with behaviourial manifestations. Mr Basak is addressing the problem of non-receipt of two vital equipments on time due to which drilling operations of an Oil Company in the public sector had to be suspended causing financial and non-financial losses. While familiarizing the readers with the organizational reality where pinpointing of a problem situation is often difficult, the case raises a few important issues: Is it possible for an individual to tide over multiple organizational constraints with innovation, patience and tact and is advancement always through questioning the existing way of doing things? Readers are invited to send their responses on the case to Vikalpa Office.

Jersey Oil and Gas Unearths Wengen Prospect The Greater Buchan Area (GBA) now has four drill-ready prospects to add to discoveries already slated for development. In a new subsurface evaluation, Jersey Oil & Gas, a British-independent North Sea-focused upstream oil and gas company, has uncovered a new prospect, named Wengen, to complement its Verbier Deep, Cortina NE, and Zermatt drill-ready prospects. The four are estimated to host some 222 million bbl of P50 prospective resources, all in the immediate vicinity of Jersey’s planned GBA production facility. The consolidated Greater Buchan venture comprises Buchan field (80 million bbl), Verbier (c25 million bbl), J2 (c20 million), and Glenn (14 million). The new prospect, located in License P2170, is directly west of the Tweedsmuir field and should host some 62 million bbl of potential resources (P50), with the probabilistic range set at 31 million bbl at P90 (higher confidence) and 162 mil-lion for P10 (lower confidence). Probability of geological success is 22% for the prospect. Contractor Rockflow previously estimated the recoverable resources in the GBA at 94.7 million bbl, including the parts within P2170. In late November, Jersey announced it is taking full ownership of License P2170, which hosts most of the Verbier discovery, as part of the GBA. In March, Jersey told investors the project is fully funded and that it intends to take the project to potential industry partners via a farm-out process. An exploratory drilling campaign is being planned for 2022. Jordan Finds “Promising” Gas Reserves Near Iraq Border Jordan’s majority state-owned National Petroleum Company (NPC) has discovered “promising” natural gas in the Risha gas field along its eastern border with Iraq. Risha makes up nearly 5% of the kingdom’s consumption of natural gas of around 350 MMcf/D for power generation, Jordanian officials said. The flow of new gas supplies will raise the productivity of the gas field and help Jordan cut dependence on oil imports to fuel its power sector and industries. The country, which now imports over 93% of its total energy supplies, is burdened by a $3.5-billion annual bill, comprising almost 8% of Jordan’s GDP. Although British supermajor BP abandoned the eastern desert area in 2014 after investing over $240 million, Jordanian exploration has stepped up since 2019, boosting quantities by at least 70%, Mohammad al Khasawneh, head of NPC, said. An ambitious 10-year energy plan unveiled in 2019 aims to secure nearly half of the country’s electricity generation from local energy sources com-pared to a current 15%, according to Iraq Energy Minister Hala Zawati. The plan is meant to diversify local energy sources by expanding investments in renewable and oil shale to reduce costly foreign fuel imports, Zawati added. ExxonMobil Discovers Hydrocarbons Offshore Suriname ExxonMobil and Petronas have discovered several hydrocarbon-bearing sandstone zones with good reservoir qualities in the Campanian section of the Sloanea-1 exploration well on Block 52 offshore Suriname, adding to ExxonMobil’s finds in the Guyana-Suriname basin. The well was drilled by operator Petronas. ExxonMobil said in November that it is prioritizing near-term capital spending on advantaged assets with the highest potential future value. Maersk Drilling reported in early July that it had secured the Maersk Developer from Petronas subsidiary PSEPBV in a $20.4-million one-well exploration con-tract offshore Suriname. The semisubmersible rig drilled the Suriname-Guyana basin well to a total depth of 15,682 ft. “We are pleased with the positive results of the well,” Emeliana Rice-Oxley, Petronas’ vice president of upstream exploration, said. “It will provide the drive for Petronas to continue exploring in Suriname, which is one of our focus basins in the Americas.” Block 52 covers an area of 1.2 million acres and is located approximately 75 miles offshore north of Paramaribo. The water depths on Block 52 range from 160 to 3,600 ft. ExxonMobil E&P Suriname BV, an affiliate of ExxonMobil, holds 50% interest in Block 52. PSEPBV is operator and holds 50% interest. CNOOC Starts Production on Penglai 25-6 Oil Field Area 3 Project China National Offshore Oil Corporation (CNOOC) announced on 14 December that its Bohai Sea Project - the Penglai 25-6 oil field area 3 - has started production ahead of schedule. The biggest offshore oil field and the second biggest oil field in China, the Penglai is located in the south central Bohai Sea, with average water depth of about 27 m. In addition to fully utilizing the existing processing facilities of Penglai oil fields, the project has built a new wellhead platform and plans 58 development wells, including 38 production wells and 20 water-injection wells. The project is expected to reach its peak production of approximately 11,511 B/D of crude oil in 2023. Six successful appraisal wells were also drilled, which confirmed the presence of hydrocarbons in reservoirs located with-in Miocene, Lower Minghuazhen, and Guantao sandstones. The Penglai 19-3 oil field is located in Block 11/05 of Bohai Bay, approximately 235 km southeast of Tanggu. The production-sharing contract for block 11/05 was signed between CNOOC and ConocoPhillips China (COPC) in December 1994; the field was discovered jointly by CNOOC and COPC in 1999. The oil field was developed in two phases. Phase I production started in December 2002; production from the wellhead platform C, which is tied back temporarily to the production facilities of Phase I, began in June 2007. Since June 2020, CNOOC has announced five production startups: the Jinzhou 25-1 oilfield 6/11 area project, the Liuhua 16-2 oilfield/ 20-2 oil-field joint development project, the Nan-bao 35-2 oilfield S1 area project, the Luda 21-2/16-3 regional development project, and the Qinhuangdao 33-1S oilfield phase-I project. In Q3 2020, CNOOC achieved a total net production of 131.2 million BOE, which the company said represented an increase of 5.1% year over year. Production from China was said to have increased by 10.4% year over year to 88.6 million BOE. In November, CNOOC revealed that the Liuhua 29-1 gas field had begun production; in September, the company said the Bozhong 19-6 condensate gas field pilot area development project had also begun. Operator CNOOC holds 51% interest while COPC holds 49% interest in the Penglai 25-6 oilfield area 3 project. Equinor’s Snorre Expansion Project Starts Ahead of Schedule, Below Cost Work began in December on the Snorre Expansion Project in the southern part of the Norwegian Sea. This increased-oil-recovery project will add almost 200 million bbl of recoverable oil reserves and help extend the productive life of the Snorre field through 2040. The expansion project is proposed in blocks 34/4 and 34/7 of the Tampen area, approximately 124 miles west of Florø in the Norwegian North Sea. “I am proud that we have managed to achieve safe startup of the Snorre Expansion Project ahead of schedule in such a challenging year as 2020. In addition, the project is set to be delivered more than NOK 1 billion below the cost estimate in the plan for development and operation,” Geir Tungesvik, Equinor’s executive vice president for technology, projects, and drilling, said. Originally scheduled to come onstream in the first quarter of 2021, the project comprises 24 new wells divided into six subsea templates, drilled to recover the new volumes. Bundles connecting the new wells to the platform have been installed, in addition to new risers. The project also includes a new module and modifications on Snorre A. In December 2017, Equinor submitted a modified plan for development and operation of the field. With the expansion, the recovery factor will increase from 46 to 51%, representing significant value for a field with 2 billion bbl of recoverable oil reserves. Wind power will supply about 35% of the power requirement for the Snorre and Gullfaks fields. The Hywind Tampen project, featuring 11 floating wind turbines, should start up in Q3 2022. The investments in the expansion project total NOK 19.5 billion (2020 value). The project has had substantial spin-off effects for the supply industry in Norway, particularly in eastern Norway and in Rogaland. The Snorre field partnership comprises Equinor (operator) 33.27%, Petoro 30%, Vår Energi 18.55%, Idemitsu 9.6%, and Wintershall Dea 8.57%. Petrobras To Sell Entire Stake in Onshore Field of Sergipe Petrobras on 11 December signed a contract with Energizzi Energias do Brasil to sell its entire stake in the onshore field of Rabo Branco, located south of the Carmópolis field in the Sergipe-Alagoas Basin, Sergipe state. The Rabo Branco field is part of the BT-SEAL-13 concession. The $1.5-million sale is in line with Petrobras’ strategy to cut costs and improve its capital allocation, to focus its resources increasingly on deep and ultradeep waters. The average oil production of the field, from January to October 2020, was 138 B/D. Energizzi Energias do Brasil will own 50% stake in the Rabo Branco field; operator Produção de Óleo e Gás (Petrom) holds the remaining 50%. On 10 December, Petrobras closed the divestiture of its full ownership in four onshore fields at the Tucano Basin site in the state of Bahia. Petrobras sold its entire interest to Eagle Exploração de Óleo e Gás (Eagle). Petrobras earned $2.571 million from this sale, in addition to the $602,000 that the company received at the time of signing the sale contract, for a total of $3.173 million. BP, Reliance Announce First Gas From Asia’s Deepest Project Oil-to-telecom conglomerate Reliance Industries Limited (RIL) and BP have started production from India’s first ultradeepwater gas project, the first of three such projects in the KG D6 block. The R Cluster gas field is located off the east coast of India, about 60 km from the existing KG D6 control-and-riser platform (CRP), and comprises a subsea production system tied back to the CRP via a subsea pipeline. It is the deepest offshore gas field in Asia at a depth greater than 2000 m. The companies’ next project, the Satellites Cluster, is expected to come on stream this year, followed by the MJ project in 2022. These projects will utilize the existing hub infrastructure in the KG D6 block. “Growing India’s own production of cleaner-burning gas to meet a significant portion of its energy demand, these three new KG D6 projects will support the country’s drive to shape and improve its future energy mix,” BP Chief Executive Bernard Looney said. The R Cluster field is expected to reach plateau gas production of about 12.9 million standard cubic meters per day (MMscm/D) in 2021. Peak gas production from the three fields should be 30 MMscm/D (1 Bcf/D) by 2023, about 25% of India’s domestic production, and will help reduce the country’s dependence on imported gas. RIL is the operator of KG D6 with a 66.67% interest; BP holds a 33.33% participating interest.

The Sail River is the position in the center of Pekanbaru City and is affected because of the tides. Urban pollution is a significant giver to the Sail River of water quality degradation. The study was conducted between June and August to assess estimation pollution load Sail River and pollution levels using the Pollution Index method. Water quality parameters measured are physical (temperature, TSS) and chemical (pH, dissolved oxygen, BOD, COD, Pb, oil and grease, nitrate, as well as phosphate). The results showed that the Sail River was classified as lightly polluted at high tide and low tide. The pollution index value at high tide is higher with a range of 3.65-3.92 than at low tide (2.93-3.39). TSS is the highest pollution load of the Sail River that a value of 1079.83 mg/second at high tide and 1075.29 mg/second at low tide. The lowest pollution load is oil and grease at low tide (0.47 mg/second). Thus, it is necessary to control the level of water pollution in the Sail River.

Abstract Many of the world’s largest cities are near the ocean, and more than 600 million people live within 10 meters of sea level. A lot of hard-to-replace infrastructure—ports, power plants, transmission lines, oil refineries, sewage treatment facilities, telecommunications cables, and highways—have been built close to the water. As glaciers melt and warmed waters expand in volume, that infrastructure will be threatened. In the face of this relentless tide, engineers are looking at what can be done.

Eni Starts Area 1 Production off Mexico via MODEC FPSO MODEC said first oil has flowed through FPSO MIAMTE MV34 operating in the Offshore Area 1 block in the Bay of Campeche off Mexico. The contractor was appointed by Eni Mexico for the supply, charter, and operation of the FPSO in the Eni-operated Offshore Area 1 block in 2018. The charter contract will run for an initial 15 years, with options for extension every year thereafter up to 5 additional years. Moored in a water depth of approximately 32 m some 10 km off Mexico’s coast, the FPSO is capable of handling 90,000 B/D of oil, 75 MMcf/D of gas, and 120,000 B/D of water injection with a storage capacity of 700,000 bbl of oil. The FPSO boasts a disconnectable tower yoke mooring system, a first-of-its-kind design in the industry. The system was developed to moor the FPSO in shallow water, while also allowing the unit to disconnect its mooring and depart the area to avoid winter storms and hurricanes in the Gulf of Mexico. The mooring system was developed by MODEC subsidiary SOFEC Inc. The mooring jacket was fabricated in Altamira, Mexico. Eni Starts Production from Ndungu EP Development Italy’s Eni has started production from the Ndungu Early Production (EP) development in Block 15/06 of the Angolan deep offshore, via the Ngoma FPSO. With an expected production rate in the range of 20,000 B/D, the project will sustain the plateau of the Ngoma, a 100,000-B/D, zero-discharge, and zero-process-flaring FPSO, upgraded in 2021 to minimize emissions. A further exploration and delineation campaign will be performed in Q2 2022 to assess the full potential of the overall assets of Ndungu. Ndungu EP is the third startup achieved by Eni Angola in Block 15/06 in the past 7 months, after Cuica Early Production and the Cabaca North Development Project. Block 15/06 is operated by Eni Angola with a 36.84% share. Sonangol Pesquisa e Produção (36.84%) and SSI Fifteen Ltd. (26.32%) comprise the rest of the joint venture. Aramco Discovers Natural Gas in Four Regions Saudi Aramco has discovered natural gas fields in four regions of the kingdom, the Saudi Press Agency (SPA) reported, citing Energy Minister Prince Abdulaziz bin Salman. The fields were found in the Empty Quarter desert located in the central area of the kingdom, near its northern border and in the eastern region, he said, according to SPA. Saudi Arabia wants to increase gas production and boost the share of natural gas in its energy mix to meet growing electricity consumption and to make more crude available for export. The minister said an unspecified number of fields were discovered and he mentioned five by name: Shadoon, in the central region; Shehab and Shurfa, in the Empty Quarter in the southeastern region; Umm Khansar, near the northern border with Iraq; and Samna in the eastern region. Two of the gas fields, Samna and Umm Khansar, were said to be “nonconventional” and possibly shale finds. Lukoil Completes Area 4 Deal in Mexico Russian producer Lukoil has completed a deal to become a lead stakeholder in an Area 4 shallow-water asset adjacent to Tabasco and Campeche in Mexico. Under the deal, Lukoil has acquired a 50% stake in the asset from US independent Fieldwood Energy, which filed for US bankruptcy protection in August 2020, for $685 million. The original deal was priced at $435 million; the additional $250 million is related to expenditures Fieldwood incurred since 1 January 2021. Fieldwood committed to invest $477 million to increase oil production from the Ichalkil and Pokoch fields from the current level of 25,000 B/D to a plateau level of 115,000 B/D. Situated in water depths between 35 and 45 m, the fields’ recoverable hydrocarbon reserves amount to 564 million BOE, more than 80% of which is crude oil. Production started in Q4 2021; current average oil production has exceeded 25,000 B/D. The approved work program includes drilling three development wells (two on Ichalkil and one on Pokoch), upgrading three production platforms, and performing seismic reprocessing and petrophysical studies.

TotalEnergies Discovers Large Oil Field off Namibia TotalEnergies has made a significant discovery of light oil with associated gas on the Venus prospect, located in block 2913B in the Orange Basin, offshore southern Namibia. The Venus 1-X well encountered approximately 84 m of net oil pay in a good-quality Lower Cretaceous reservoir. The find’s potential reserves are estimated at 2 billion bbl of oil. “This discovery offshore Namibia and the very promising initial results prove the potential of this play in the Orange Basin, on which TotalEnergies owns an important position both in Namibia and South Africa,” said Kevin McLachlan, senior vice president exploration at TotalEnergies. “A comprehensive coring and logging program has been completed. This will enable the preparation of appraisal operations designed to assess the commerciality of this discovery.” Block 2913B covers approximately 8215 km2 in deep offshore Namibia. TotalEnergies is the operator with a 40% working interest, alongside QatarEnergy (30%), Impact Oil and Gas (20%), and NAMCOR (10%). CNPC Scoops Ishpingo Drilling Contract The first drilling contract at the Ishpingo oil field near Ecuador’s Yasuni National Park has been awarded to China National Petroleum Corp. (CNPC), Energy Minister Juan Carlos Bermeo told Reuters. Following the approval of a new hydrocarbon law and legislation, Ecuador plans to move forward with auctions and competitive processes for securing foreign and domestic capital for oil and gas exploration, production, transportation, and refining projects. The first drilling campaign to start after an environmental license was granted for the sensitive area will involve 40 wells over the next 18 months. It will focus on the field’s allowed zone without touching an area protected by a court ruling that has prevented extending drilling. Ishpingo is the latest part of the ITT-43 oil field in Ecuador’s Amazonia region to start drilling after Tambococha and Tiputini. It is expected to produce heavy oil to be added to the nation’s output of flagship Napo crude, Bermeo said. BP Brings Hershel Expansion Project On Line in US GOM BP has successfully started production from the Herschel Expansion project in the Gulf of Mexico—the first of four major projects scheduled to be delivered globally in 2022. Phase 1 comprises development of a new subsea production system and the first of up to three wells tied to the Na Kika platform in the Mississippi Canyon area. At its peak, this first well is expected to increase platform annual gross production by an estimated 10,600 BOE/D. The BP-operated well was drilled to a depth of approximately 19,000 ft and is located southeast of the Na Kika platform, approximately 140 miles off the coast of New Orleans. The project provides infrastructure for future well tie-in opportunities. BP and Shell each hold a 50% working interest in the development. Petrobras Kicks off Gulf of Mexico Asset Sales Petrobras has begun an asset sale program in the Gulf of Mexico, in line with the company’s strategy of debt reduction and pivot toward Brazilian deepwater production. The package for sale includes the company’s 20% stake in MP Gulf of Mexico (MPGoM) which holds ownership stakes in 15 fields in partnership with Murphy Oil. In addition to partnership-operated fields, MPGoM owns nonoperated interests in Occidental’s Lucius, Kosmos’ Kodiak, Shell’s Habanero, and Chevron’s St. Malo fields. During the first half of 2021, Petrobras’ share of production was 11,300 BOE/D. ExxonMobil Liza Phase 2 Underway off Guyana ExxonMobil started production of Liza Phase 2, Guyana’s second offshore oil development on the Stabroek Block; total production capacity is now more than 340,000 B/D in the 7 years since the country’s first discovery. Production at the Liza Unity FPSO is expected to reach its target of 220,000 bbl of oil later this year. The Stabroek Block’s recoverable resource base is estimated at more than 10 billion BOE. The current resource has the potential to support up to 10 projects. ExxonMobil anticipates that four FPSOs with a capacity of more than 800,000 B/D will be in operation on the block by year-end 2025. Payara, the third project in the block, is expected to produce approximately 220,000 BOPD using the Prosperity FPSO vessel, currently under construction. The field development plan and application for environmental authorization for the Yellowtail project, the fourth project in the block, have been submitted for government and regulatory approvals. The Liza Unity arrived in Guyana in October 2021. It is moored in water depth of about 1650 m and will store around 2 million bbl of crude. ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. is the operator and holds 45% interest. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Petroleum Guyana Ltd. holds 25%. Dragon Finds Oil in Gulf of Suez UAE’s Dragon Oil has discovered oil in the Gulf of Suez, according to a statement from the Egyptian Minister of Petroleum and Mineral Resources. The field contains potential reserves of around 100 million bbl inside the northeastern region of Ramadan. That estimate makes it one of the largest oil finds in the region over the past 2 decades. Development plans were not reported but reserve numbers could expand, the ministry said. The oil field is the first discovery by Dragon Oil since it acquired 100% of BP’s Gulf of Suez Petroleum assets in 2019. Dragon Oil, wholly owned by Emirates National Oil Co., holds 100% interest in East Zeit Bay off the southern Gulf of Suez region. The 93-km2 block lies in shallow waters of 10 to 40 m.

ABSTRACT The equipment under study is an innovative boom arrangement consisting of a ramp boom and three other conventional booms of different drafts. To optimize the design, an advanced volume of fluid (VOF) algorithm is developed to calculate oil-water flows in the complex geometry. The effects of the gravity, current velocity, and depth; spans between the conventional booms; the ramp boom's draft and inclination angle; oil viscosity; and density are considered in the present numerical modeling. A comparison was made between the computational simulation and the laboratory experiment of the boom arrangement and satisfactory results were obtained. From the numerical investigations, it is found that the oil slick flowing behind the ramp boom is similar to that of a solid object traveling under the influence of gravity. To achieve a high performance, the ramp slope should be as small as possible and the span of the boom system should cover the oil's “landing distance.” Under the current tide conditions, the simulations show that the small amplitude tide may improve the system's performance, while the large amplitude tide significantly deteriorates it. The smaller angular-frequency tide is more harmful to the system, especially if the tide's amplitude is large at the same time.

In recent years, Aker BP has explored and developed a number of digital improvements to optimize production. The underlying business drivers are meant to improve efficiency, increase production and reserves, decrease costs, and reduce the carbon footprint from operations. The example described in this article has innovative elements of digitalization and automation of workflows which provide a new approach for better handling of slugging in subsea developments with long tiebacks. The new solution has a potential for optimizing production and limiting the amount of flaring. Flow Instabilities in the Vilje Field The Aker BP-operated Vilje field in the Norwegian Continental Shelf has occasionally experienced production-flow instabilities in the production pipelines and risers due to slugging. The company worked with Turbulent Flux to develop a software solution, the FLUX Stability Adviser, to continuously and precisely monitor production in real time. Field Description and Outline of Problem The Vilje field is a subsea development with three horizontal producers tied back to the Alvheim floating production, storage, and offloading (FPSO) facility through a production line longer than 20 km. The inlet separator at Alvheim is shared with other third-party developments. After an initial period of dry-oil production at the field, which started production in 2008, the oil rate has gradually decreased as a result of increased water cuts (WC) over time. Gas lift has been used to sustain production. The occasional slugging at the inlet separator had been controlled by increasing the backpressure to the production line and/or shutting in one of the producers. However, this practice affects production potential and may lead to production losses or deferral. Explanation of the Solution The two companies developed a Stability Adviser application to advise operators of the settings to optimize production in real time while lowering the risks related to slugging at any point in time. The developed solution runs on a cloud infrastructure with an interactive web-user interface. The main user interface contains a 3D heat map which is based on output from a series of pre-run transient simulations and a statistical analysis of the associated slugging severity. The model quality of the pre-run simulations was benchmarked with field data, and a similarity index was introduced to evaluate the degree of matching. Transient multiphase flow simulations represent the state of the art in the prediction and analysis of slugging behavior in multiphase transport pipelines (both terrain-induced and hydrodynamic slugging). These simulators capture and follow slugs as they are forming along the pipeline. That said, these simulations are time consuming, which limits their usefulness in a real-time operational context.

Dugong Reserve Estimate Tightens on New Well Results Neptune Energy redefined the estimated reserves at its Dugong discovery in the Norwegian sector of the North Sea to between 40–108 million BOE based on the results of appraisal well 34/4-16 S. Prior to this appraisal, the operator believed the prospect could hold as much as 120 million BOE. The main objective of the well was achieved by establishing the oil/water contact. Neptune Energy said the new range will be subject to further detailed analysis and review, and a drillstem test on the well is planned at a later stage. The appraisal well was drilled using the Odjfell-operated semisubmersible Deepsea Yantai in about 330 m of water. The Dugong discovery will either be linked to nearby infrastructure or developed as a standalone development. Dugong is located 158 km west of Florø, Norway, and is close to the existing production facilities of the Snorre and Statfjord fields. The Dugong license partners are Neptune Energy (operator and 45%), Petrolia NOCO (20%), Idemitsu Petroleum Norge (20%), and Concedo (15%). Oselvar P&A Work Underway Decommissioning of the DNO Norge-operated Oselvar field has kicked off with the operator contracting semisubmersible Borgland Dolphin for plug-and-abandonment work. Oselvar is in the southern part of the Norwegian sector in the North Sea, 20 km southwest of the Ula field. The water depth is 70 m. Oselvar was discovered in 1991, and the plan for development and operation was approved in 2009. The field was developed via a trio of subsea wells tied to Ula. Production started in 2012 and ended in 2018. The Borgland Dolphin was moved to the field on 20 March. The rig recently went through a series of upgrades including the installation of new shale shakers, new standpipe manifold, an upgraded drilling control system, and an upgraded helideck. Decommissioning must be completed by the end of 2022. Equinor Green Lights FPSO for Brazil’s BM-C-33 Development Equinor, together with license partners Repsol Sinopec Brasil and Petrobras, have approved an FPSO-based development concept for BM-C-33, a gas/condensate field located in the Campos Basin pre-salt in Brazil. Subsea wells will be tied back to the FPSO located at the field. Gas and oil/condensate will be processed at the floater to sales specifications and exported. Crude will be offloaded by shuttle tankers and shipped to the international market after ship-to-ship transfer. A newbuild hull has been selected to accommodate the field’s planned 30-year lifetime. “BM-C-33 holds substantial volumes of gas,” said Veronica Coelho, Equinor’s country manager in Brazil. “A completion of the ongoing liberalization of the natural gas market in Brazil in line with the current plan, is key for the further development of the project. BM-C-33 is an asset that can generate value for the society, both through the creation of direct and indirect jobs, ripple effects, and through a gas supply that can induce industrial growth, as has happened in other countries.” Gas export capacity is planned for 16 million cubic meters per day with average exports expected to be 14 million cubic meters per day. Daily oil processing capacity is of 20,000 cubic meters per day. The gas-export solution is based on an integrated offshore gas pipe-line from the FPSO to a new dedicated onshore gas-receiving facility inside the Petrobras TECAB site at Cabiúnas, before connecting to the domestic gas-transmission network. Lundin Makes Small Discovery Near Edvard Grieg Lundin Energy Norway encountered a 10-m oil column with its wildcat well 16/4-13 S about 15 km south of the Edvard Grieg field in the central part of the North Sea. The operator added that about 7 m of the encountered column was of moderate to poor reservoir quality. The oil/water contact was encountered 1950 m below the sea surface. The entire reservoir, including the water zone, comprises conglomeratic sandstones in a thickness of about 380 m. Preliminary estimates place the size of the discovery between 0.5 and 1.4 million cubic meters of recoverable oil equivalent. The licensees will assess the discovery regarding a possible tie-in to the Solveig field. The well was drilled by Seadrill semisubmersible West Bollsta and will be permanently plugged and abandoned. The rig will now move to drill the 16/4-BA-1H production well on the Solveig field. Wintershall Gets Permit for Bergknapp Appraisal The Norwegian Petroleum Directorate granted Wintershall Dea Norge a drilling permit for well 6406/3-10 A to spud a follow-up probe to a discovery made in April 2020. The Bergknapp appraisal will be drilled from the Odjfell semisubmersible Deepsea Aberdeen once the rig has concluded the drilling of wildcat well 6507/4-2 S for Wintershall in production license 211. The Bergknapp appraisal will be drilled about 8 km west of the Maria field in the Norwegian Sea. The discovery well 6406/3-10 intersected an oil column of at least 60 m in the Garn formation and an oil column of at least 120 m in the Tilje formation. Preliminary estimates of the Bergknapp discovery indicate it could hold between 26–97 million BOE. The find is in production license 836 S where Wintershall is the operator and holds a 40% stake. The other licensees are DNO Norge (30%) and Spirit Energy Norway AS (30%). The area in this license comprises parts of Blocks 6406/2 and 6406/3. Guyana Says Liza Hits First-Phase Capacity Guyana’s President Irfaan Ali announced that the first phase of the Liza offshore crude project had achieved its intended full-production capacity of around 130,000 B/D. Ali told virtual attendees at the Guyana Basin Summit that he expected an additional 10 exploration and appraisal wells to be drilled off Guyana this year. He said the second phase of the Liza project, operated by ExxonMobil, would begin in 2022. The consortium led by Exxon, which includes partners Hess and CNOOC Ltd., has made 18 discoveries containing more than 8 billion bbl of recoverable oil and gas in Guyana’s Stabroek block. Equinor and Partners in Barents Bounty Equinor and partners Vår Energi and Petoro have struck oil in exploration well 7220/7-4 in production license 532 in the Barents Sea. Recoverable resources are so far estimated at between 31–50 million BOE. The well was drilled about 10 km southwest from the well 7220/8-1 on the Johan Castberg field. “Succeeding in the Barents Sea requires perseverance and a long-term perspective,” says Nick Ashton, Equinor’s senior vice president for exploration in Norway. “This discovery strengthens our belief in the opportunities that exist, not least around the Castberg, Wisting, Snøhvit, and Goliat areas.” The well, drilled by semisubmersible Transocean Enabler, struck 109 m of oil in the Stø and Nordmela formations. The top reservoir was encountered at a vertical depth of 1788 m below sea level. The expected gas cap was not encountered in the well. The well was not formation tested, but extensive data acquisition and sampling took place. Equinor said further development of the discovery toward the planned infrastructure for the Johan Castberg field will be considered at a later stage. Exploration well 7220/7-4 is the first of four planned exploration wells for Equinor in the Barents Sea this year. Eni Strikes Light Oil at Cuica Eni has made a new light-oil discovery in Block 15/06 at its Cuica prospect in the deep waters offshore Angola. The prospect is located inside the Cabaça Development Area and close to the Armada Olombendo FPSO (East Hub). Eni estimates Cuica could hold between 200 and 250 million bbl of oil in place. The Cuica-1 NFW was drilled as a deviated well by Seadrill-operated drillship Sonagol Libongos in 500 m of water and reached a total vertical depth of 4100 m, encountering an 80-m total column of reservoir of light oil (38 °API) in sandstones of Miocene age with good petrophysical properties. The discovery well is going to be sidetracked up-dip to be placed in an optimal position as a producer well. According to Eni, data collection from the well indicates an expected production capacity of around 10,000 BOPD. Cuica is the second significant oil discovery inside the existing Cabaça Development Area. The well location, intentionally placed close to East Hub’s subsea network, will allow a fast-track tie-in of the exploration well and relevant production. Eni expects the well could be on line within 6 months. Following the discoveries of Kalimba, Afoxé, Ndungu, Agidigbo, Agogo and appraisals achieved between 2018 and 2020, Cuica represents the first commercial discovery in Block 15/06 after the relaunch of the exploration campaign post-2020 COVID-19 pandemic. The discovery confirms the exploration potential of the block. A 3-year extension of the exploration period of Block 15/06 was recently granted until November 2023. The Block 15/06 joint venture comprises Eni (operator, 36.8421%), Sonangol P&P (36.8421%), and SSI Fifteen Ltd. (26.3158%). No Injuries Reported in West Mira Incident An equipment failure onboard Northern Ocean semisubmersible West Mira resulted in production equipment descending to the seabed. The rig owner said no one was injured and the well at the location was secured “with three barriers in place.” The unit was in the process of lowering the equipment on the Wintershall-operated Nova field. “While lowering a x-mas tree from West Mira, the winch wire snapped when the tree was five meters below the sea surface. The x-mas tree sunk to the seafloor 368 meters below water level. Eight people were working in the area of the rig where the incident occurred in safe distance from moving equipment,” said Wintershall. The rig manager, Seadrill Europe Management AS, and Wintershall are conducting investigations into the incident and have agreed to a plan to secure the production equipment. “A remote operated vehicle (ROV) was sent to the seafloor to assess the situation,” added the oil company. “The ROV survey showed no risk of discharge of well fluids or hydrocarbons and the x-mas tree has been localized on the template.”

Shell Signs Concession for Oman Block 10 Shell, along with its partners OQ and Marsa Liquefied Natural Gas LLC (a joint venture between TotalEnergies and OQ), have signed a concession agreement with the Ministry of Energy and Minerals on behalf of the government of the Sultanate of Oman to develop and produce natural gas from Block 10. The parties also signed a separate gas sales agreement for gas produced from the block. The two agreements follow an interim upstream agreement signed in February 2019. The concession agreement establishes Shell as the operator of Block 10, holding a 53.45% working interest, with OQ and Marsa LNG holding 13.36% and 33.19%, respectively. For the initial phase, Petroleum Development Oman (PDO) is building the infrastructure for the project, including the main pipeline to the Saih Rawl gas processing facility, on behalf of the Block 10 venture partners. The venture will drill and hook up wells to maintain the production beyond the initial phase. The block is expected to reach production of 0.5 Bcf/D. Startup is expected within the next 2 years. In addition, Shell and Energy Development Oman (EDO) signed an agreement to process the natural gas from Block 10 in EDO’s Saih Rawl facility. Shell and the government have agreed that, in parallel to the development of Block 10, Shell will develop options for a separate downstream gas project in which Shell could produce and sell low-carbon products and support the development of hydrogen in Oman. Equinor Encounters Oil at Toppand Equinor has discovered oil in the Troll and Fram area in exploration wells 35/10-7 S and 35/10-7 A in the Toppand prospect. Preliminary calculations indicate between 21 million and 33 million BOE of recoverable reserves. Well 35/10-7 S encountered an oil column of around 75 m in the lower part of the Ness formation and in the Etive formation. There were also traces of hydrocarbons in the shale- and coal-dominated upper part of the Brent Group. A total of around 68 m of effective sandstone reservoir of good to very good reservoir quality was encountered in the Ness and Etive formations combined. Exploration well 35/10-7 A encountered a 60-m oil-filled sandstone-dominated interval in the lower part of the Ness formation and in the Etive formation. A total of around 67 m of effective sandstone reservoir of good to moderate quality were encountered in the Ness and Etive formations combined. Geir Sørtveit, senior vice president for exploration and production west operations for Equinor, said, “We are pleased to see that our success in the Troll- and Fram area continues. We also regard this discovery to be commercially viable and will consider tying it to the Troll B or Troll C platform. Such discoveries close to existing infrastructure are characterized by high profitability, a short payback period, and low CO2 emissions.” These wells are the second and third exploration wells in Production License 630. The license was awarded in the 2011 Award in Predefined Areas. The wells were drilled around 8 km west of the Fram field and 140 km northwest of Bergen. Equinor holds a 50% stake and operates Toppand. Partner Wellesley holds the remaining 50% interest. Petrobras Sells Polo Carmópolis Stake to Carmo Petrobras has signed a deal to sell its stake in the onshore Polo Carmópolis area to Carmo Energy for $1.1 billion. The operator said $275 million would be paid up front, another $550 million when the deal closes, and a further $275 million 1 year after closure of the deal, which still needs regulatory approval. The Polo Carmópolis area comprises 11 onshore concessions in the state of Sergipe. Petrobras said in a statement that it is increasingly concentrating its resources on deep and ultradeepwater assets, where it has shown a competitive edge over the years, producing better-quality oil and with lower greenhouse-gas emissions. The Carmópolis Cluster recorded an average production of 7,600 BOPD and 43,000 m3/D of gas from January to November 2021. Eni, EGPC in $1-Billion Pact To Explore Gulf of Suez, Niger Delta Egyptian General Petroleum Corp. (EGPC) has signed an agreement with Italian energy group Eni for oil exploration in the Gulf of Suez and Nile Delta regions. The deal is valued at no less than $1 billion of investments, the petroleum ministry said in late December. The agreement also included a commitment from Eni to additionally spend “not less than $20 million” to drill four wells, the ministry added in a statement. The deal comes as part of the ministry’s strategy to increase production rates and to attempt to offset the natural decline of wells by using the latest technologies in oil-producing areas. Last October, Eni announced three new discoveries in the Meleiha and South West Meleiha concessions in the Western Desert. Eni has been operating in Egypt since 1954 with a current production of about 360,000 BOED. Chevron Transfers Stake in Suriname Block 5 to Shell Chevron has transferred one-third of its 60% equity interest in an offshore Suriname block for which it has a production-sharing agreement to a unit of Royal Dutch Shell, Suriname’s state oil company confirmed. Paradise Oil Company, a subsidiary of Suriname’s state-run Staatsolie, retains its 40% stake in the Block 5 venture as a nonexecutive partner, according to the farmout contract. Staatsolie and Chevron signed a production-sharing contract last October for Block 5, which covers an area of 2235 km2. The deal marked the first time that Staatsolie will participate as a partner in offshore activities. Equinor Increases Ownership in the Statfjord Field Equinor has entered into an agreement to acquire all of Spirit Energy’s production licenses in the Statfjord area which spreads across the Norwegian and UK continental shelves and are developed by three integrated production platforms (Statfjord A, B, C). All licenses are operated by Equinor. Equinor will pay $50 million, plus a contingent payment linked to commodity prices for the period between October 2021 to December 2022. The transaction has a commercial effective date from 1 January 2021, which is expected to result in a net payment to Equinor at closing. Spirit Energy’s daily production from the Statfjord area in the third quarter of 2021 was around 21,000 BOED. The transaction is part of a larger deal including Spirit Energy’s shareholders, Centrica Plc and Stadtwerke München, who are exiting their portfolio in Norway and selling their assets to Sval Energi. The sale to Sval Energi includes all assets with the exclusion of Statfjord. Statfjord marked its 40th year of production in 2019. One of the earliest oil fields on the Norwegian Continental Shelf, it has produced 5.1 billion BOE. Equinor has recently launched a plan to extend the life of the field toward 2040. The closing of the transaction is subject to certain conditions, including customary government approval, and is expected to be completed by the first half of 2022. Shell Hits Oil at Blacktip North in US GOM Shell has struck oil at the Blacktip North prospect located in the Alaminos Canyon block 336 in the deepwater US Gulf of Mexico. The Blacktip North well encountered about 300 ft net oil pay at multiple levels. The well was drilled to a total depth of 27,770 ft by Transocean drillship Deepwater Poseidon. Blacktip North is about 30 miles northeast of the Whale discovery, 4.5 miles northeast of the 2019 Blacktip discovery, and 42 miles from the Perdido spar hub platform. Shell operates the Blacktip North prospect with an 89.49% interest. Spain’s Repsol holds the remaining 10.51% stake. Petrobras Plans Equatorial Margin Drilling Program Petrobras is preparing to drill the first of 14 planned wells at South America’s new deepwater frontier, the Equatorial Margin at its Northern maritime border, a company executive told the World Petroleum Congress in December. Petrobras plans to invest $2 billion in exploration at the Equatorial Margin through 2026, Reservoir Executive Manager Tiago Homem said. The company estimates an overall investment of $2.5 billion in seismic activities over the same period. CLOV Tieback Goes Onstream Offshore Angola TotalEnergies, operator of Block 17 in Angola, has begun production from the CLOV Phase 2 project, connecting to the existing CLOV FPSO. The tieback project is expected to reach a production of 40,000 BOED in mid-2022. Located about 140 km from the Angolan coast, in water depths from 1100 to 1400 m, the CLOV Phase 2 resources are estimated at around 55 million BOE. Block 17 is operated by TotalEnergies with a 38% stake, Equinor (22.16%), ExxonMobil (19%), BP Exploration Angola Ltd. (15.84%), and Sonangol P&P (5%). The contractor group operates four FPSOs in the main production areas of the block: Girassol, Dalia, Pazflor, and CLOV. Canacol Strikes Gas With Siku-1 in Colombia Canacol Energy’s Siku-1 exploration well encountered 33 ft true vertical depth of net gas pay with an average porosity of 20% within the primary Cienaga de Oro sandstone reservoir target. The company has completed casing the well and will return with a workover rig in early 2022 to complete and tie the well into permanent production. The well was drilled to a total depth of 8,825 ft. The rig was mobilized to drill the Clarinete-6 development well, which reached a total depth of 7,478 ft measured depth and encountered 174 ft true vertical depth of net gas pay. The well was tied into the Clarinete production manifold and has been placed on permanent production. Next up for the rig is the Toronja-2 development well, which is targeting gas-bearing sandstones within the Porquero sandstone reservoir. Following the completion of that well, the rig will be mobilized to spud the Carambolo-1 exploration well, expected in the second half of February. The well is expected to take 5 weeks to drill and complete.

Abstract The Sail River flows through the Pekanbaru City area which functions as a hydrological reservoir and main drainage channel. This river is affected by tides. Development along the Sail River Basin may affects the aquatic ecosystems. The research was conducted to determine the quality of the Sail River water and how it relates to the tides. Sampling was carried out two times during June-July 2021 in high and low tide conditions. The water quality parameters measured were temperature, TSS, pH, dissolved oxygen, BOD, COD, oil and fat, and Pb metal. Results showed that the temperature, COD, and Pb were significantly different at high tide and low tide conditions. On the other hand, during low and high tides condition, the value of TSS, pH, dissolved oxygen, BOD, oil, and fat were not significantly different. Dissolved oxygen levels during high and low tide ranged from 2.00 -3.00 mg/l and 1.00 -1.70 mg/l respectively. The Pb content during high and low tides ranged from 0.12-0.16 mg/l. In the present study, the values of dissolved oxygen and Pb content does not meet the water quality standards of Government Regulation No. 22/2021 (Class III).

ExxonMobil, Partners Tout New Angola Block 15 Discovery ExxonMobil has made a new oil discovery with the Bavuca South-1 exploration well in Block 15 offshore Angola. The well is part of the Angola Block 15 redevelopment project targeting to deliver around 40,000 B/D of new oil production. According to ExxonMobil, the well encountered 30 m of hydrocarbon-bearing sandstone. The probe is located approximately 365 km northwest of Luanda and was drilled in 1100 m of water by the Valaris DS-9 rig. As the block’s operator, ExxonMobil is leading the installation of new technology and a multiyear drilling program aimed at adding new production volumes to help offset natural production declines. There have been 17 previous discoveries on Block 15: Hungo, Kissanje, Marimba, and Dikanza in 1998; Chocalho and Xikomba in 1999; Mondo, Saxi, and Batuque in 2000; Mbulumbumba, Vicango, and Mavacola in 2001; Reco Reco in 2002; and Clochas, Kakocha, Tchihumba, and Bavuca in 2003.

The drilling program comprises a main bore (6407/8-8 A) with an optional sidetrack (6407/8-8 S) based on the outcome of the exploration well. Neptune Energy operates the well with a 30% working interest. Partners include OKEA ASA, 30%; Pandion Energy AS, 20%; and Vår Energi ASA, 20%. Petrobras Strikes Oil Near Sepia Field Petrobras has a new oil find at its 4-BRSA-1386D-RJS (Pedunculo) well in the extreme northwest of the Sépia field in Brazil’s Santos Basin. The well spud in late July in a water depth of 2200 m, and the oil-bearing interval was verified by logs and fluid samples. According to Petrobras, the effective thickness of the oil column is one of the largest ever recorded in Brazil. The discovery is in the Sepia coparticipation area and comprises the Sepia block acquired by Petrobras (100%), and the Sépia-ECO block, which was acquired in December 2021 in the ANP’s second bidding round of surplus volumes. Petrobras (operator) was awarded Sépia-ECO along with partners TotalEnergies, QatarEnergy, and Petronas Petróleo Brasil Ltda., with Pré-Sal Petróleo SA as manager. The Sépia shared reservoir is currently producing 170,000 B/D. Petrobras also successfully completed the test at the pioneer well 1-BRSA-1381-SPS (Curaçao) in the pre-salt of the southwestern part of the Santos Basin. The new discovery is located 240 km from the city of Santos-SP, at a depth of 1905 m, in the Aram Block. The test evaluated a thick range of pre-salt carbonate reservoirs, in which it was possible to know its productivity through dynamic production data, according to Petrobras. During the test, oil samples were collected that will be characterized by laboratory analyses. The consortium will continue its activities in the Aram Block, aiming to evaluate the dimensions and commerciality of the new accumulation. The block was acquired in March 2020, in the sixth bidding round of the ANP, under the production-sharing regime, with Pré-Sal Petróleo SA as manager. Petrobras is the operator of the block (80% interest) in partnership with CNPC 20%. Shell, Murphy Eye Fresh Mexican Gulf Wildcats Shell is preparing to drill an exploration test in the Salina basin in offshore Mexico. According to Mexican hydrocarbons regulator CNH, the supermajor intends to spud the Jokol-1EXP wildcat in Block 28 starting in January 2023. The operator plans to use drillship Maersk Voyager for the work. The rig has been drilling the Zanderij-1 probe in Block 42 offshore Suriname and is expected to depart for Mexico soon. The Jokol-1EXP well is set to test a prospective light-oil reservoir at final depth of around 5586 m. The wellsite is roughly 40 km southwest of the Tamha-1EXP well. Meanwhile, Murphy Oil is drilling ahead on the deepwater Tulum-1EXP, where it hopes to tap 150 million BOE in reserves off the coast of Tabasco. The operator’s Mexican subsidiary, Murphy Sur, received authorization from CNH earlier this year. Murphy will use the Valaris DPS-5 semisubmersible to target lower Miocene and Oligocene formations and is drilling Tulum-1EXP as a deviated well to a depth of 5569 m. Tulum-1EXP is the second exploratory well of the Block 5 consortium led by Murphy Sur (40%), with partners PC Carigali Mexico Operations, Petronas’ Mexican subsidiary, and Wintershall Dea holding 30% each. Block 5 is in the center of the highly touted Salina Basin, a deepwater area in Mexico with significant hydrocarbon potential. CNOOC Has Certified Gas Find With Baodao 21-1 The proved gas-in-place of CNOOC’s Baodao 21-1 gas field has been certified at 50 billion m3 by the Chinese government. Baodao 21-1 gas field is in Baodao Sag, Qiongdongnan Basin, Western South China Sea in water depths ranging from 660 to 1570 m. The main gas-bearing zone is the Paleogene Lingshui formation, and the discovery is in condensate gas reservoirs. The discovery well Baodao 21-1 completed at a total depth of 5188 m, encountering 113 m of gas pay. The well is tested to produce an average of 587,000 m3 of natural gas per day. Baodao 21-1 is the first deepwater, deep-stratum large gas field in the South China Sea, realizing the biggest discovery in more than half a century in Songnan-Baodao Sag, according to CNOOC. ADNOC Sets Well-Length Record Abu Dhabi National Oil Company (ADNOC) said it set a new world record for the longest oil and gas well at its Upper Zakum Concession. Stretching 50,000 ft, the well is around 800 ft longer than the previous world record set in 2017. ADNOC Drilling drilled the well from Umm Al Anbar, one of ADNOC Offshore’s artificial islands. The extended-reach wells will tap into an undeveloped part of the giant Upper Zakum reservoir with the potential to increase the field’s production capacity by 15,000 B/D. Umm Al Anbar is one of Upper Zakum’s four artificial islands, serving as a hub for offshore drilling and operations. The producer added that its use of the artificial island concept has resulted in cost savings and environmental benefits compared to conventional approaches that traditionally require more offshore installations and infrastructure. New Tampen Area Wells Planned The Norwegian Petroleum Directorate issued to Equinor, Aker BP, and Var Energi a pair of drilling permits for exploration wells in the Tampen area of the Norwegian North Sea. The partnership has applied to drill the 34/6-6A wildcat in PL-554 using drilling rig Transocean Spitsbergen. The well is located to the northeast of the Visund field. Equinor will operate the well with a 40% working interest. Aker BP and Var Energi each hold a 30% stake. The second probe, 34/6-6S, was also permitted by the same partnership in the same license.

Block 2V was signed last year followed by Blocks 2W and X early this year. A total of four wells are expected to be drilled in these blocks in 2022 and 2023.

Huge quantity of produced water is salty water trapped in the oil wells rock and brought up along with oil or gas during production. It usually contains hydrocarbons as oil and suspended solids or turbidity. Therefore the aim of this study is to treat produced water before being discharge to surface water or re injected in oil wells. In this paper experimental results were investigated on treating produced water (which is obtained from Middle Oil Company-Iraq), through electrocoagulation (EC). The performance of EC was investigated for reduction of turbidity and oil content up to allowable limit. Effect of different parameters were studied; (pH, current density, distance between two electrodes, and electrolysis time). The experimental runs carried out by an electrocoagulation unit was assembled and installed in the lab and the reactor was made of a material Perspex, with a capacity of approximately 2.5 liters and dimensions were 20 cm in length, 14 cm in width and 16 cm height. The electrodes employed were made of commercial materials. The anode was a perforated aluminum rectangular plate with a thickness of 1.72 mm, a height of 60 mm and length of 140 mm and the cathode was a mesh iron. The current was used in the unit with different densities to test the turbidity removing efficiency (0.0025, 0.00633, 0.01266 and 0.0253 A/cm2).The experiment showed that the best turbidity removing was (10, 9.7, 9.2, 18 NTU) respectively. The distance between the electrodes of the unit was 3cm. The present turbidity removing was 92.33%. A slight improvement of turbidity removing was shown when the distance between the electrodes was changed from 0.5 to 3 cm with fixation of current density. The best turbidity removing was 93.5% , (7.79 NTU) when the distance between the electrodes were 1 cm. The experimental results found that concentration of oil had decreased to (10.7, 11.2, 11.7, 12.3) mg/l when different current densities (0.00253, 0.00633, 0.01266, 0.0253) A/cm2 were used, respectively with the distance between the electrodes was 3 cm. The best result of oil content decreasing was 10.7 mg/l with current density 0.0253 A/cm2. These results are within allowable limit to provide the possibility of reuse the water and can be injected in oil wells

Guyana Prepares for Offshore Licensing Round The Guyanese government is preparing to launch its first bidding round for offshore exploration and production of hydrocarbon blocks. New fiscal terms and conditions are being finalized which the country hopes will allow it to gain the maximum economic benefits. The 2022 bidding round, which according to the nation’s Department of Public Information, is expected to be officially launched soon and will be opened for several months to give interested companies sufficient time to prepare their competitive packages and bid to win the available acreages offshore. With the upcoming bidding round the government expects Guyana’s offshore areas to emerge as a potential super basin with over 11 billion BOE discovered to date. The process seeks to ensure the country gets a fairer share of revenues from oil and gas resources through improved fiscal arrangements, as well as safeguard the safety of people and the environment by following international best practices in offshore development. The new round also aims to be competitive with other global energy projects and assure investors of stability, predictability, and security of any investment. The government seeks to balance its developmental agenda with its climate change goals. Ault Drills Successful Smackover Well in Mississippi Ault Energy completed drilling the Harry O’Neal 20-9 No. 1 in Holmes County, Mississippi, and logged productive oil results across multiple pay zones in the Smackover formation. Completion work has begun on the well, and it is expected to be on stream soon. Ault was formed by parent BitNile this past summer to make strategic oil and gas acquisitions. The company obtained participation rights with for the O’Neal No. 1 well and future oil wells when it invested $12 million in Ecoark Holdings in June. Ault Energy exercised its participation right and acquired a 40% working interest in the well, which is the first project in an expected long-term partnership between Ecoark and Ault parent companies White River and BitNile, respectively, with the intention to drill approximately 100 oil wells over 5 years. White River’s next drilling project is expected to be a 14,000-ft-deep vertical oil well in the Wilcox, Austin Chalk, and Tuscaloosa Marine Shale formations in the Coochie oil field in Concordia Parish, Louisiana. White River also plans to drill three consecutive deep vertical drilling projects at approximately 13,000 ft in the Rodessa and Hosston sand formations on the Pisgah Field Lease in Rankin County, Mississippi. Hess Brings Another Llano Well On Stream Hess brought its Llano-6 well in the Gulf of Mexico (GOM) on stream. The new well, like the other Llano wells, is tied back to Shell’s Auger facility. Hess is planning increased activity in the Llano area based on the success of Llano-6, quality of the reservoir, and adjacent high-value prospects. Hess holds a 50% interest in the long-producing Llano field, located about 150 miles off the Louisiana coast in the Garden Banks area in an estimated 2,600 ft of water. Shell, the operator, holds a 27.5% interest, and ExxonMobil has the remaining 22.5%. The field was discovered in 1997 and achieved first oil in 2004. Recent seismic reprocessing and analysis confirmed additional development opportunities in the field. Hess expects more high-value opportunities at Llano with wells planned for 2023 and 2024 and is finalizing plans for a year-long drilling campaign starting in early 2023 that will focus on tieback and hub-class opportunities in the GOM. Mubadala Discovers Gas Field Off Malaysia Mubadala Energy and its partners have announced a new gas discovery offshore Malaysia via the Cengkih-1 exploration well in Block SK 320. The exploration well was drilled to a total depth of 1680 m and encountered a 110-m gas column in the Miocene Cycle IV/V pinnacle carbonate reservoirs.

The measures operation is an important component of borehole operation, and the operation effects directly affect the increase of oil and gas production. In perspective of the present reality of borehole operation company, the authors analyze the commonly used type of measures on the oil field, summarize six indicators to evaluate the measures operation effect, and give the quantitative calculation method for six evaluation indicators. Through the experts grading method, we can obtain all the weights of indicators and then establish the fuzzy comprehensive evaluation model of operation effect of measures. The evaluation model can be used to evaluate the operation effect of single well, oil block, or the branch company. Based on the actual data of measures operation of a branch company, using the fuzzy comprehensive evaluation approach to evaluate each block in the branch company, this paper obtained the same conclusion as the qualitative analysis.

Abstract At the fields of Rosneft Oil and Gas Company, effective technologies are used to increase oil production and oil recovery ratio. To this end, systematic work is carried out to extract hard-to-recover oil reserves. Side boreholes (BS) cutting, which helps to increase oil recovery and actually replaces well compaction. Piezometric and unprofitable wells, as well as wells with leaking production strings, are identified when selecting candidate wells for planning BS and horizontal wells (HW). Maps of residual oil-saturated thicknesses are also considered, according to which localization zones of oil reserves not involved in the development are determined, in order to select areas for drilling. For rational selection of measures, forecasting of drilling results should be carried out using a hydrodynamic model and full seismic studies. First of all, the proximity of the water injection front from the existing injection pool of wells is determined in order to avoid the risks of sharp watering.

ABSTRACT Laboratory studies were conducted to determine the fate of fertilizers proposed for application to the Alaska shoreline in support of the Alaskan Oil Spill EPA Bioremediation Project. Fertilizer application is thought to provide indigenous organisms with nutrients that appear to be limited on ocean beaches. The experiments were developed strictly to test the durability, release rates, and application procedures of a variety of fertilizer types. The effects of tidal movement on a beach were simulated by two separate conditions, static and dynamic. The static condition represented periods when the beach material was under water and turbulence was at a minimum. This condition was simulated in the laboratory by submerging the nutrient in a beaker of simulated seawater (with or without beach material, depending on the nutrients being tested). These experiments ran continuously over a three-month period, with water exchanges according to a planned schedule. Nutrient concentrations were measured in the exchanged water. Dynamic conditions represented the forces on beach material as the water moved from low to high tide and back to low tide. In the laboratory, the condition was simulated by applying the nutrients to beach material piled in one end of a long, narrow tray placed on a rocker table. When the rocker table was operating and enough seawater had been added to cover the beach material (in the rocker table's low position), a gentle sloshing of the water over the materials resulted. These experiments generally lasted one to two hours, during which time liquid samples were collected for nutrient analyses. Durability of the fertilizers was measured by visual observation and freeze/thaw determinations. The experimental setup was economical and performed well. The fertilizer most suited for field trial was found to be isobutyraldehyde diurea briquettes, which produced a slow, continuous release of nutrients.

In this paper, the numerical hydrodynamic simulation has been carried out by using measured topographic data and related tidal information. The oil particle tracking module of MIKE21 is adopted to study the processes of drifting and turbulent diffusion of oil particles on the water surface, where four working conditions, namely, static wind, dominant wind direction, maximum wind direction and most unfavourable wind direction, are applied. Results show that Xiushan Island will be the apparent ‘victim’ in the cases of oil spill in all wind directions. Meanwhile, due to the existence of Changbai Island and Xiushan Island, the diffusion process of oil particles is obviously retarded to impact the protected marine areas.

ABSTRACT The oceans are a major source of food, livelihood, recreation, trade, and, in the case of many desert or semi-desert countries, a source of fresh water. In addition oceans serve as the primary carriers of another precious resource, petroleum. Saudi Aramco's environmental policy is to ensure that its operations do not create undue risk to the environment or public health. It also states that the company will conduct its operation with full concern for the protection of land, air, and water from harmful pollution. To carry out this policy, the company has taken several important precautionary and preparatory measures to ensure minimization of pollution from its operation at the various sectors. Saudi Aramco has adopted the age-old maxim that an ounce of prevention is better than a pound of cure. Since oil is a major potential source of marine pollution, the company has started with minimizing the accidental introduction of oil into the marine environment.

ABSTRACT Seven years after the spill of an estimated 140,000 gallons of a mixture of No. 6 and No. 2 fuel oils into the Patuxent River, a study was conducted to assess recovery at 24 oiled sites compared with 24 unoiled sites. Metrics included stem density, stem height, belowground biomass and polynuclear aromatic hydrocarbons (PAH) at depths of 0–10 cm and 10–20 cm, and soil toxicity of the 0–10 cm interval. Half of the soil samples contained the spilled oil; total PAHs varied by 1–2 orders of magnitude between the top and bottom intervals, reflecting high oil heterogeneity. The oil had lost 22–76% of its initial PAH content, although there had been little to no additional PAH weathering since Fall 2000 and Summer 2001. Stem density and height were significantly lower in oiled versus unoiled sites for Spartina alterniflora but not S. cynosuroides. In contrast, belowground biomass was significantly lower in S. cynosuroides but not S. alterniflora. Based on toxicity tests and sediment quality benchmarks, 25% of the soils were expected to be toxic to many organisms (ESB-TUFCV values > 3.0; PMax > 0.65). There are likely two factors limiting natural weathering processes in the marsh soils: slow physical removal processes and low oxygen availability. The interior marsh habitat is flooded by daily tides through many small channels. The marsh surface has a lot of micro-topography with low areas between dense clumps of stems that hold pools of water during low tide. The sediments in these low areas are very soft and water saturated. Obviously, during spring low tides, the marsh soils do drain as low as 30 cm, because the oil penetrated to these depths in some areas. The falling tide drains through dense vegetation. Tidal flushing may have been a mechanism for removal of bulk oil stranded on the surface initially; however, it would not be effective at mobilizing oil from below the marsh surface. There are few bioturbating benthic biota in these marshes. Photo-oxidation does not occur below ground. Therefore, the only other removal mechanism would be microbial degradation.

At present, oil spills are a potential threat to coastal states. In many sea areas of the sea, the phenomenon of "black tide" is common. There are many causes for this situation such as collisions, accidents of water transport vehicles (especially oil tankers), oilrig incident, oil spill incident due to geological changes, waste oil burglary on the sea. For Vietnam, about 200 million tons of oil are transported each year through the sea. In the process of transporting and exploiting offshore, there may be incidents leading to oil spills into the sea, polluting the marine environment. According to statistics, in the past 20 years, about 10 oil spills have been recorded annually, especially in 2012, there were 12 cases affecting the estuarine and coastal environment of Vietnam and coastal ecosystems as well as coastal resorts. This article presents a report on oil spills occurring in Vietnam and policies of the Vietnamese government to respond to oil spills.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 202246, “Wheatstone: What We Have Learned in Early Production Life,” by John Pescod, SPE, Paul Connell, SPE, and Zhi Xia, Chevron, et al., prepared for the 2020 SPE Asia Pacific Oil and Gas Conference and Exhibition, originally scheduled to be held in Perth, Australia, 20–22 October. The paper has not been peer reviewed. Wheatstone and Iago gas fields, part of the larger Wheatstone project, commenced production in June 2017. The foundation subsea system includes nine Wheatstone and Iago development wells tied back to a central Wheatstone platform (WP) for processing. Hydrocarbons then flow through an export pipeline to an onshore processing facility that includes two liquefied-natural-gas (LNG) trains and a domestic gas facility. The complete paper highlights some of the key learnings in well and reservoir surveillance analysis and optimization (SA&O) developed using data from early production. Asset Overview Chevron Australia’s Wheatstone project is in the North West Shelf region offshore Australia (Fig. 1). Two gas fields, Wheatstone and Iago (along with a field operated by a different company), currently tie into the WP in the Northern Carnarvon Basin. These two gas fields are in water depths between 150 and 400 m. The platform processes gas and condensate through dehydration and compression facilities before export by a 220-km, 44-in., trunkline to two 4.45-million-tonnes/year LNG trains and a 200 tera-joule/day domestic gas plant. A Wheatstone/Iago subsea system consisting of two main corridors delivers production from north and south of the Wheatstone and Iago fields to the WP. Currently, the subsea system consists of nine subsea foundation development wells, three subsea production manifolds, two subsea 24-in. production flowlines, and two subsea 14-in. utility lines. The nine foundation development wells feed the subsea manifolds at rates of up to 250 MMscf/D. These wells have openhole gravel-pack completions for active sand control and permanent downhole gauges situated approximately 1000-m true vertical depth above the top porosity of multi-Darcy reservoir intervals for pressure and temperature monitoring. All wells deviate between 45 and 60° through the reservoir with stepout lengths of up to 2.5 km. The two subsea 24-in. production flowlines carry production fluids from the subsea manifolds to two separation trains on the WP. Each platform inlet production separator can handle up to 800 MMscf/D. The two 14-in. utility flowlines installed to the subsea manifolds allow routing of a single well to the platform multiuse header, which can direct flow into the multiuse separator (MUS) or other production separators at a rate of 250 MMscf/D.

The purpose of this study is to clarify the effects of wave and tidal actions on the penetration of spilled oil stranded on tidal flats and to evaluate the influence of the penetrated oil on seawater infiltration using tidal flat simulator. A simulator used was composed of tidal flat, wave maker, tide controlling device, temperature controlling system and computer controlling system. The infiltrations of seawater and fuel oil C into tidal flats were visualized using transparent glass beads as tidal flat sediments. Penetration behaviour of the spilled oil into the sediments was significantly different from that of seawater. Seawater infiltrated into the sediments both by wave action and tidal fluctuation, while fuel oil C penetrated by tidal movement only. The infiltration of seawater was reduced by penetrated oil. This result indicates that the penetrated oil diminishes infiltration of seawater into the sediments and thus results in the reduction in the supply of oxygen, nutrients, and organic matterto the benthic organisms in tidal flat.

An investigation of the oil spill after the wreck of the tanker ‘Erika’ on 16 December 1999 showed that the maritime area around the town of Le Croisic (between the Vilaine and Loire river estuaries) was severely contaminated by the resulting black tide. Samples of sediment, oil and water were collected during several missions to the Le Croisic headland and analysed. The toxicity of the oil was tested on two organisms, the harpacticoid copepod Tigriopus brevicornis and the alga Enteromorpha intestinalis. The tests showed only slight degradation of the oil after three months. In laboratory conditions, the toxicity of the sediment contaminated by the oil was apparent on the copepod after four days of exposure. Seawater in contact with the oil also had an effect on the alga.

Oil spills in estuaries are less studied and less understood than their oceanic counterparts. To address this gap, we present a detailed analysis of estuarine oil spill transport. We develop and analyse a range of simulations for the Humber Estuary, using a coupled hydrodynamic and oil spill model. The models were driven by river discharge at the river boundaries and tidal height data at the offshore boundary. Satisfactory model performance was obtained for both model calibration and validation. Some novel findings were made: (a) there is a statistically significant (p < 0.05) difference in the influence of hydrodynamic conditions (tidal range, stage and river discharge) on oil slick transport; and (b) because of seasonal variation in river discharge, winter slicks released at high water did not exhibit any upstream displacement over repeated tidal cycles, while summer slicks travelled upstream into the estuary over repeated tidal cycles. The implications of these findings for operational oil spill response are: (i) the need to take cognisance of time of oil release within a tidal cycle; and (ii) the need to understand how the interaction of river discharge and tidal range influences oil slick dynamics, as this will aid responders in assessing the likely oil trajectories.

The spreading of oil in an open ocean may cause serious damage to a marine environmental system. Thus, an accurate prediction of oil spill is very important to minimize coastal damage due to unexpected oil spill accident. The movement of oil may be represented with a numerical model that solves an advection-diffusion-reaction equation with a proper numerical scheme. In this study, the spilled oil dispersion model has been established in consideration of tide and tidal currents simultaneously. The velocity components in the advection-diffusion-reaction equation are obtained from the shallow-water equations. The accuracy of the model is verified by applying it to a simple but significant problem. The results produced by the model agree with corresponding analytical solutions and field-observed data. The model is then applied to predict the spreading of an oil spill in a real coastal environment.

After a short review of the usefulness of maritime structures, particularly vertical wall breakwaters, long term observations of hydrogeological breaking on the bottom of Italy's Seas, as caused by the subaqueous source of fresh water, are discussed. The correlation between hydrogeological breaking and wave motion perturbation produced by compressed air or by oil is presented. These considerations are related to the observations of Admiral Alessandro Cialdi on the morphological breaking of waves above sand banks, thus producing calmness in the upper water. Therefore, it appears possible to establish a very suggestive analogy between the atomic disintegration of the transformation of potential energy of the oscillatory tide wave into kinematic energy of its components (because of breaking), in accordance with the disintegration of the circular motion.

Dayun area is one of the centers of oil palm plantation in Siak Regency. State-owned company that develops oil palm plantation in Dayun is PT Perkebunan Nusantara V (PTPN V) which is the first company developing oil palm plantation in Siak Regency. The oil palm plantations cause various effects to the environment; one of them is the decreasing water availability for the water stakeholders.

ABSTRACT In April 2010, the explosion of the Deepwater Horizon (DWH) drilling platform led to the release of nearly 4.9 million barrels of crude oil into the Gulf of Mexico. The oil was brought to the supratidal zone of beaches (landward of the high tide line) by waves during storms, and was buried during subsequent storms. The objective of this paper is to investigate the biodegradation of subsurface oil in a tidally influenced sand beach located at Bon Secour National Wildlife Refuge and polluted by the DWH oil spill. Two transects were installed perpendicular to the shoreline within the supratidal zone of the beach. One transect had four galvanized steel piezometer wells to measure the water level. The other transect had four stainless steel multiport sampling wells that were used to collect pore water samples below the beach surface. The samples were analyzed for dissolved oxygen (DO), nitrogen, and redox conditions. Sediment samples were also collected at different depths to measure residual oil concentrations and microbial biomass. As the biodegradation of hydrocarbons was of interest, a biological model based on Monod kinetics was developed and coupled to the transport model MARUN, which is a two dimensional (vertical slice) finite element model for water flow and solute transport in tidally influenced beaches. The resulting coupled model, BIOMARUN, was used to simulate the biodegradation of total n-alkanes and polycyclic aromatic hydrocarbons (PAHs) trapped as residual oil in the unsaturated zone. Model parameter estimates were constrained by published Monod kinetics parameters. The field measurements, such as the concentrations of the oil, microbial biomass, nitrogen, and DO, were used as inputs for the simulations. The biodegradation of alkanes and PAHs was predicted in the simulation, and sensitivity analyses were conducted to assess the effect of the model parameters on the modeling results. Simulation results indicated that n-alkanes and PAHs would be biodegraded by 80% after 2 ± 0.5 years and 3.5 ± 0.5 years, respectively.

A tide-dominated estuarine reservoir is an important oil reservoir. However, due to the force of bidirectional water flow, its internal structure is complex, and the heterogeneity is serious. Accurately establishing the tide-dominated estuarine reservoir model is a great challenge. This paper takes the Mackay River oil sands reservoir in Canada as the research object to establish the elaborate geological model of a tide-dominated estuarine reservoir. Through the meticulous depiction of core data, 14 kinds of lithofacies and nine kinds of architectural elements are identified, and the lithological and electrical response in sedimentary architectural elements is established. On this basis, the plane and vertical distribution of architectural elements, as well as the spatial superimposition patterns, are depicted and characterized through well seismic combination and plane and section interaction, and the representative plane and section architecture maps are obtained as 2D training images (TIs) for multi-point statistical modeling. The 2D TI is scanned by 2D data template to obtain the multi-point statistical probability of the 2D spatial architectural pattern. Then, the 2D multi-point probability is fused to generate three-dimensional (3D) multi-point statistical probability by the probabilistic fusion. Finally, Monte Carlo sampling is used to predict the spatial distribution of architectures, and an elaborate geological model of a tide-dominated estuarine reservoir is established. Compared with the traditional sequential indication modeling method, the point-to-point error of the model section based on the 2D section reconstruction method is only 25.92%, while the sequential indication modeling method is as high as 58.52%. Even far from the TI, the point-to-point error of the 2D section model is 33.13%. From the cross-validation, the average error of the 2D section is 11%, while the sequential indicator modeling error is 23.1%, which indicates that the accuracy of 2D reconstruction of the estuarine reservoir model is high, and this method is suitable for the establishment of the tide-dominated estuarine reservoir model.

ABSTRACT The Oil Spill Prevention and Response Division of the Texas General Land Office has taken their oil spill prevention efforts to new heights. Beyond assessing penalties, beyond providing far-reaching educational programs, and beyond conducting extensive patrolling efforts, their most recent prevention initiative significantly decreases bilge oil spills in a non-threatening, alliance-building manner. This new prevention effort, known as the Texas General Land Office Bilge Water Reclamation Program, provides a convenient, environmentally responsible way to dispose of oily bilge water at no cost to the owners and operators of the vessels using the facilities. Strategically placed facilities collect oily bilge water from commercial or recreational fishing vessels and process it so effectively that the filtered water can be discharged directly into the adjacent waterway and the oily product can be recycled. To date, the facilities have cleaned more than 150,000 gallons of contaminated water and generated 20,000 gallons of used engine oil for use by a waste oil recycling company.

In this work, the combustion of heavy oil and its emulsions with water, in the cement kilns, was investigated in experiments on an industrial scale. The performance of the cement rotary kilns, used in Tartous Company for cement and construction materials, was studied when they were employed to be operated with heavy fuel oil (HFO) and with the water phase of emulsified heavy oil containing 8 vol. % water and 92 vol. % heavy fuel oil (HFO). The emulsified water/heavy fuel oil (W/HFO) with 8 vol. % of water content showed no separation and contained the smallest and most homogeneous water-in-HFO (W/HFO) droplets after stability tests. Four rotary kilns have been operated for 4 months with a regular heavy fuel oil HFO and W0.08/HFO0.092. It has been found that the micro-explosion, observed in W0.08/HFO0.092, improved the kiln efficiency and reduced the fuel consumption by 10.31% in the case of normal feeding while the fuel saving increases with decreasing the feeding rate and reaches 12.99 at low feeding rate. The effect of emulsified fuel on the composition of Portland cement clinker that produced in Tartous Company for cement and construction materials using these two types of fuels is investigated. It is found that the influence is practically negligible on the Alite and Ferrite phases of clinker composition while the influence on the other two phases is important.

ABSTRACT The movement of oil on the water surface is a result of meteorologic and oceanographic processes. Attempts to contain or divert surface oil using booms should factor these processes into the development of deployment tactics. Attempts to deploy booms, disregarding physical and environmental conditions often have met with failure. Differing physical parameters affect water circulation and the movement of oil in the nearshore environments of reef/lagoon and barrier inlet systems; generalized models identify the primary features of each of these two systems for selection of appropriate methods of boom deployment. Circulation patterns across reefs are dominated by wave-driven and tidal-driven forces that carry water across the reef crest into the low energy lagoonal environment. Within the lagoon, tidal and wind stress forces become important factors that drive the circulation systems. Barrier island inlets that form in meso-tidal environments have circulation patterns that are dominated by cyclical tidal forces. In the narrow inlet throats current velocities are frequently too great for booms to contain oil. In this situation diversion of surface oil to areas of low current speeds can be used to protect sensitive lagoonal environments. During the early stages of a flooding tide, current inflow through the inlet is in marginal channels and at this tidal stage oil could be diverted to the shoreline before it enters the inlet throat.

By the end of 2020, the company is expected to extract 3 billion cubic feet of natural gas per day.

The development of the waste minimization program for Amoco Oil Company's refineries is discussed, from its conception through its evolution and present-day status. Beginning with a commitment from top management, a corporate waste minimization mission was defined; goals and objectives were set; and a program was outlined. In 1987, a task force was formed to evaluate the current refining system waste minimization activities and to establish a program baseline. A waste minimization coordinator was tasked with defining a program to update current activities and to keep the refining system focused on meeting the established objectives. This includes educating the refining system on waste minimization definitions and issues; effectively communicating goals, ideas, and methods; and team building to maintain enthusiasm. The role of Amoco's R&D department in the waste minimization program is presented, including the development of software to track waste generation, processing, disposal, and costs. Finally, briefcase-studies of successfully implemented source control and resource recovery projects are presented.

Waterflood introduces in the oil field a couple of years ago. Several waterflood schemes have been implemented in the fields to get the best incremental oil, such as peripheral injection, pattern waterflood, and etcetera. Many waterflood schemes are not working properly to boost the oil recovery due to unpredicted and unexpected water tide array. Then, the tracer practice started to be used for getting a better picture of the transmissibility reservoir as well as the direction of water pathway. This practice honors the parameters, such pressure, water cut, GOR, and rates. The streamline modeling is used to map the tracer, and it concludes that the selection of location of the injector should be based on the highest oil recovery achieved. Subsequently, the cyclic water injection method is one alternative. Apparently, this approach yields a quantify incremental recovery. This research utilizes the pressure different approach to figure out the route of water in the formation. The inter-well tracer technique in this modeling study is a tool to review communication between injectors and producers in the existing pattern. Many scenario should be tried to find the best options for the new pattern opportunities. In parallel, a innovative scheme of waterflood technique should be implemented too for escalating oil recovery. The stream pathway observes a new potential of the waterflood scheme. It is called "cyclic injection" scheme. The novelty of this approach is the ability to solve the poor sweep efficiency due to improper pathway of water influx in the oil bearing".

Quality Control procedures were developed and implemented on behalf of a UK water company for the procurement of a suite of numerical models of advection and dispersion from effluent outfalls. The paper explains the need for quality control and describes the methods employed. These were a set of technical audits and performance trials. Some interesting technical issues arose from this work. These examined: the sensitivity of shoreline solutions to variations in parameter values; showed that simulations must be of sufficient duration to reach convergence; showed that the surface wind creates a shear dispersion effect which has an important effect on an effluent plume; and investigated the choice of diffusion coefficients with reference to along and across tide diffusivities and the need for consistency between nested models.

To compensate for the research defects of strong subjectivity in determining oil spill amount, insufficient consideration of wharf distribution, and incomplete indexes for reflecting the influence degree of oil spill accidents on water sources, and to enhance the supervision efficiency of the supervision department, this paper constructs a risk assessment system of water sources under the influence of the wharf group. The system includes a wharf group division method considering the wharf distribution situation; the calculation method of oil spill amount at wharves considering the oil tank capacity of main ship types and the production supervision risk at the wharves; the calculation method of the oil spill amount at the wharf group considering the wharf number, distribution density, production supervision risk and wharf oil spillage; the determination method for the influence degree of oil spill at the wharf group on the water sources and judgment method of supervision level at the wharf group, which takes the arrival time of oil slicks, the duration of over-standard petroleum concentration and the maximum over-standard multiple of petroleum concentration at the water intake as indexes; the method of determining the risk of oil spill accidents at the water source considering the cumulative effect of oil spill at the wharf group on the risk of the water sources; and the environmental risk assessment method of water sources considering oil spill accident risk and the anti-risk ability. Applying this system to the environmental risk assessment of the Zhengrunzhou water source in Zhenjiang City, we discovered that the flow field, wind field, oil spill location and oil spill amount were correlated with the influence degree of oil spill accidents on water sources, for which the flow field demonstrated the strongest correlation, while the wind field presented the weakest. The supervision level of the wharf group is mainly sub-key or non-key levels, but the level of the wharf group SD07 is approximate to the key supervision level during rising tide. Due to the strong anti-risk ability of the Zhengrunzhou water source, the environmental risks of the Zhengrunzhou water source under different working conditions are scarcely different and belong to the medium-risk level.

Access to clean water is a basic right for the community, but the fulfillment of this basic right is often constrained by difficult geographical conditions. The existence of community development programs through CSR can be an entry point in fulfilling access to clean water, especially in remote locations. This research is a comparative case study between the practice of implementing the CSR Program in providing access to clean water which is carried out by 2 companies located in the same location, namely between company X which is engaged in oil and gas exploration, and company Y which is engaged in oil processing. The study was conducted using a qualitative descriptive method with data collection carried out through in-depth observation by researchers and direct interviews in the period from March to November 2021. As a result, the community-based development approach carried out by company Y was more successful and was able to increase community participation in program management. In addition, community participation is also able to increase the involvement of local communities with their customs in managing the sustainability of the program.

This case study was conducted in a manufacturing company that experienced a breakdown in a power generator set. A standard investigation was carried out by opening the crankcase cover and checking the dipstick. The results of the visual inspection showed that the engine oil was contaminated with water. Therefore, this study was conducted to further analyze the causes of oil contaminated with water in the unit being handled using fault tree analysis (FTA). As a result, cracks were found in the cylinder liner due to pitting on the outer liner with a pitting depth of more than 2 mm. In our analysis, pitting is formed due to the presence of air bubbles in the cooling system. Based on FTA, the formation of air bubbles is caused by the quality of the coolant. We also found that the coolant used was not added with any additives.

Purpose – The purpose of this paper is to explore influences of green advertising and social activism during one of the worst adverse public relations episodes in history: the British Petroleum (BP) Deep Water Horizon oil spill. Design/methodology/approach – The study uses self-congruency theory and perception of fit to explore the influence of green advertising and social activism on attitudes toward BP’s advertising, commitment to the environment, brand, and company. The survey data cover periods before, during, and after the spill. Findings – Mean ratings for the BP brand were lower during the oil spill for respondents who viewed an environmental ad as compared to those viewing an ad lacking environmental content. Comparison of attitudes toward BP’s environmental commitment, advertising, company, and brand reveal differences between activist and non-activist respondents across all four attitudinal scales during the oil spill. Practical implications – The study finds that lack of fit between corporate social responsibility communications and social responsibility performance raises the potential for a significant backlash against BP. Originality/value – The paper utilizes unique data that include survey responses before during and after the BP Deep Water Horizon oil spill. Empirical analyses of attitudes toward advertising, company, and brand over the life cycle of an adverse public relations event are among the first of their kind. Similarly, analyses of differences in activist and non-activist attitudes toward a company operating in a high-environmental risk industry are also among the first ever.
