Streszczenie:

The essential oils from two members of the Asteraceae ( Acanthospermum hispidum DC. aerial parts, and leaves of Tithonia diversifolia (Hemsley) A. Gray), growing wild in Osun State, Nigeria, have been characterised by combined gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses. Twenty-nine components have been fully identified and grouped into monoterpene hydrocarbons (22.2%), oxygenated monoterpenes (4.6%), sesquiterpenes hydrocarbons (58.2%) and oxygenated sesquiterpenes (10.8%) in A. hispidum. The main constituents of the oil were β-caryophyllene (28.0%), α-pinene (15.9%) and bicyclogermacrene (11.0%) among the hydrocarbon compounds, and bisabolol (8.9%) and carvacrol methyl ether (4.1%) among the oxygenated components. Tithonia diversifolia essential oil comprised seventeen components and was characterised by a predominant content of monoterpene hydrocarbons (87.9%), cis-β-ocimene (43.7%), α-pinene (28.6%) and limonene (12.0%) being the main compounds. Sesquiterpenes represented ca. 10% oil, as sum of hydrocarbons and oxygenated components. A new chemotype is established for T. diversifolia, while the Nigerian A. hispidum is being reported for the first time as a new source of essential oil with some distinction in composition from those of other sources.

The volatile constituents and insecticidal activity of the essential oil obtained by hydrodistillation of pulverized air-dried leaves of Dehinbollia pinnata Schum. & Thonn (Sapindaceae) growing in Nigeria were studied. The constituents of the oil were analyzed by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). The percentage yield of the oil was 0.04% (v/w). Fourteen compounds were characterized, representing 94.0% of the total volatile component of the oil. The major constituents of the oil were hexahydrofarnesyl acetone (37.5%), farnesyl acetone (17.2%) and geranyl acetone (14.6%). The essential oil, at a concentration of 120 mg/mL, displayed 100% mortality against Sitophilus zeamais at 72 h with a LC50 > 40.00 mg/mL air.

Introduction: Safety leadership is the process of interaction between leaders and followers, through which leaders exert their influence on followers to achieve organizational safety goals under the circumstances of organizational and individual factors. Objective: This study was aimed to assess leadership style and safety in oil and gas servicing firms in Portharcourt, Nigeria. Methods: A cross-sectional study was conducted among the junior-staff of the oil servicing firms. The Taro Yamane equation was used to generate appropriate sample size of 389 respondents from 16240 workers. Data analyses was done using analysis of variance (ANOVA). Results: It was established that 230 (59%) respondents agreed that, leaders checked staff work on a regular basis to assess their progress and learning. Many respondents (62%) averred that leaders didn’t gave any incentives for extra work. Also, 338 (87%) respondents adduced that changes in policies were discussed with workers before they were carried out but, the input of the workers were not required, neither staff were expected to be innovative as opined by 76% respondents and leadership emphasis on the importance of quality was sustained. Albeit, workers weren’t allowed to contribute to control standards based on perception of problems. The characteristics of leadership displayed in the companies imply the transactional type. This was because the rapport between workers and leaders wasn’t cordial. Conclusion: The study therefore strongly recommends a review of the leadership style adopted for oil and gas workers in the area, while improving on the worker/leader relationships.

The essential oil from the stem bark and leaves of Dennettia tripetala Bak. f. (Annonaceae) growing wild in Ondo State, Nigeria, has been characterized by combined gas chromatography (GC) and gas chromatography-mass spectrometry (GC- MS) analyses. Overall, thirty-six components have been fully identified, thirty-two in the stem-bark oil, and only seven in the leaf oil. In both oils, 2-phenylnitroethane was the main component, ranging between 70 – 76% of the total oils. The profile of the stem bark oil was characterized by a large number of sesquiterpenes, whereas among the few components in the leaf oil, linalool reaches over 17%. When both oils were assayed for antimicrobial activity, only Staphylococcus aureus was susceptible to the stem-bark oil which was more active than leaf oil. For protective effects against UV radiation–induced peroxidation in phosphatidylcholine (PC) liposomes, stem-bark oil also showed greater effectiveness. Activity of the leaf oil against Trichomonas gallinae, was also remarkable.

Purpose The purpose of this qualitative case study is to explore strategies for the de-escalation of kleptocracy in Nigeria’s oil and gas industry. Design/methodology/approach The author used a qualitative case study to facilitate the generation of data from eight research participants in semi-structured open-ended interviews. Findings The themes that emerged from analysis of interview transcriptions were high self-control, traditional African oath of office, whistleblowing, stiffer penalties for corrupt officials, education and training, self-regulation and sonic therapeutic intervention. Research limitations/implications Interviewees might withhold information regarding their insights on strategies for de-escalating kleptocracy. That was beyond my control. Practical implications The study results provided leaders with insightful comprehension of anti-kleptocracy policy in the oil and gas industry. Therefore, leaders would benefit and advance their decision-making process on the development and implementation of an anti-kleptocracy strategy to revamp the financial value of the oil and gas industry in Nigeria. Social implications The results of the study have the potential to contribute to positive social change by enlightening government leaders and anti-corruption agencies on strategies to de-escalate kleptocracy in the oil and gas industry. Originality/value The study’s uniqueness enabled filling the gap in financial crime literature as well as an added value to the applied management and decision sciences domain.

The stem bark and leaves of Daniellia oliveri were obtained from two sites, Batsari and Zurmi, in Nigeria. Leaves of Leptoderris micrantha were obtained from Agbagi, Nigeria. Essential oils of these plants were obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The major components in the bark essential oil of D. oliveri were δ-cadinene (12.8%), α-muurolene (6.7%), α-calacorene (5.9%), and caryophyllene oxide (5.5%). The major components in the leaf essential oils from Batsari and Zurmi, respectively, were humulene epoxide II (8.0% and 16.3%), caryophyllene oxide (7.4% and 12.4%), pentadecanal (8.9% and 6.0%), phytone (6.5% and 2.2%), δ-cadinene (5.3% and 3.0%), and α-muurolene (5.3% and 2.6%). The major components in the leaf essential oil of L. micrantha were incensole (16.2%), phytone (15.4%), pentadecanal (13.7%), α-pinene (7.7%), and iso-phytol (5.2%). The essential oils were screened for antibacterial activity against Bacillus cereus, Cutibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Pseudomonas aeruginosa, and Serratia marcescens, and for antifungal activity against Aspergillus fumigatus, Aspergillus niger, Cryptococcus neoformans, Microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes, Trichophyton rubrum, and Candida albicans, using the microbroth dilution method. The leaf essential oils of D. oliveri and L. micrantha showed only marginal activity against the panel of microorganisms. However, D. oliveri bark essential oil showed notable antifungal activity against Aspergillus niger and Trichophyton rubrum with a minimum inhibitory concentration of 78.1 µg/mL for each. This is the first report on the essential oil compositions of D. oliveri and L. micrantha from Nigeria and their antimicrobial activities.

Lannea egregia (Anacardiaceae) and Emilia sonchifolia (Asteraceae) are plants used in traditional medicine in southwestern Nigeria. The essential oils from the leaves of L. egregia and E. sonchifolia were obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry. Both essential oils were dominated by sesquiterpenoids. The major components in L. egregia leaf essential oil were α-panasinsen (34.90%), (E)-caryophyllene (12.25%), α-copaene (11.39%), and selina-4,11-diene (9.29%), while E. sonchifolia essential oil was rich in γ-himachalene (25.16%), (E)-caryophyllene (15.72%), and γ-gurjunene (8.58%). The essential oils were screened for antimicrobial activity against a panel of bacteria and fungi and displayed minimum inhibitory concentrations ranging from 156 μg/mL to 625 μg/mL. Based on these results, either L. egregia or E. sonchifolia essential oil may be recommended for exploration as complementary antibacterial or antifungal agents.

The rice weevil (Sitophilus oryzae) is a pest of stored grain products such as rice, wheat, and corn. Essential oils represent a green environmentally-friendly alternative to synthetic pesticides for controlling stored-product insect pests. Launaea taraxacifolia is a leafy vegetable plant found in several parts of Nigeria. The leaves are eaten either fresh as a salad or cooked as a sauce. The essential oil obtained from fresh leaves of L. taraxacifolia was obtained by hydrodistillation and analyzed by gas chromatography/mass spectrometry (GC-MS). Twenty-nine compounds were identified, accounting for 100% of the oil composition. The major component classes were monoterpene hydrocarbons (78.1%), followed by oxygenated monoterpenoids (16.2%), sesquiterpene hydrocarbons (2.1%), oxygenated sesquiterpenoids (0.3%), and non-terpenoid derivatives (3.3%). The leaf essential oil was dominated by monoterpene hydrocarbons including limonene (48.8%), sabinene (18.8%), and (E)-β-ocimene (4.6%), along with the monoterpenoid aldehyde citronellal (11.0%). The contact insecticidal activity of L. taraxacifolia essential oil against Sitophilus oryzae was carried out; median lethal concentration (LC50) values of topical exposure of L. taraxacifolia essential oil were assessed over a 120-h period. The LC50 values ranged from 54.38 μL/mL (24 h) to 10.10 µL/mL (120 h). The insecticidal activity of the L. taraxacifolia essential oil can be attributed to major components limonene (48.8%), sabinene (18.8%), and citronellal (11.0%), as well as potential synergistic action of the essential oil components. This result showed L. taraxacifolia essential oil may be considered as a useful alternative to synthetic insecticides.

This study examines the potentials of film in managing conflict in the oil rich Niger Delta region of Nigeria. This is against the backdrop that since the commencement of oil production in the region in the 1960s to date, it has continued to experience one form of armed conflict or the other. These manifest in several ways such as kidnapping of foreign oil workers, vandalization of oil facilities and confrontation with security operatives by militants, leaving adverse effects on the Nigerian economy which depends on crude oil as the major source of income. The paradox of plenty or resource curse that has come to characterize the region and how it can be addressed, therefore, is what prompts the current study. Using the Nollywood film- Black November, the study demonstrates that film is an instrument that can be used effectively to manage conflicts in the region. From the viewpoint of Singhal and Rogers’ Entertainment-Education approach, the study adopts thematic analysis to identify and discuss the various themes embedded in the film. Findings indicate that several forces are behind the intractable conflict in the region as contained in the film, such as exploitation of resident communities by multinational oil companies, environmental degradation occasioned by oil spillage and gas flaring, and gross injustice, insincerity and human rights abuse by security operatives that make the people lose faith and confidence in both them and the government which they represent. Other causes include betrayal and corruption on the part of community leaders and the burning fire of patriotism in the youth who are determined to fight for their rights. Given the rich thematic embodiment of the film, the study concludes that film has potentials which, if effectively harnessed, will go a long way in managing conflicts in the society.

"Through case studies of three emerging economies - Ecuador, Nigeria and Russia - this thesis analyses the factors present to a greater or lesser degree in emerging economies, such as severe foreign indebtedness and the absence of the rule of law, that undermine the effectiveness of the legal system in protecting indigenous peoples from oil exploitation. Having identified these factors, I propose that a dual approach to the protection of indigenous peoples' traditional lands and their environment be adopted, whereby international laws that set out the rights of indigenous peoples and place duties on states in this regard, are reinforced and translated into practice through the self-regulation of the international oil industry through a voluntary code of conduct for oil companies seeking to operate on indigenous peoples' traditional lands."

Oil and gas is a major source of energy worldwide. Therefore its significance for Nigeria as a major producer cannot be understated. Notwithstanding the huge revenue derived from oil and gas, its contribution to the Gross Domestic Product (GDP) is minimal. This can be ascribed to the fact that there has been minimal indigenous participation in oil and gas projects as this has often been undertaken by the International Oil Companies (IOCs). To address this, the Federal Government awarded marginal fields and oil blocks to independent indigenous oil companies and enacted the Nigerian Oil and Gas Industry Content Development Act in 2010. This has been of great benefit to indigenous participation. However, these indigenous companies often encounter a major problem in accessing finance for their projects. This dissertation examines the challenges to financing faced by the independent indigenous oil companies and how project financing will be the best means of financing a project by these companies.

This dissertation examines the challenges of domesticating oil and gas insurance in Nigeria. The methodology adopted is both quantitative and qualitative, using questionnaire and interview to generate required data for the research. The research identified some challenges preventing domestic insurers from insuring oil and gas risks to include inadequate capital, lack of expertise and technology, inconsistencies in government policies, poor regulation and lack of innovation. Other findings revealed that the industry is male-dominated, ages of the experienced personnel in oil and gas departments are between 40 and50 and all are well educated and also with knowledge in Local Content Act. The research contributes to knowledge by using primary data from practitioners in oil and gas, which is a departure from earlier studies. It also seeks the review of the Act to make it insurance-friendly, provides new methods of practice, and brings to the attention of the umbrella association, Nigeria Insurers Association (NIA), the need to foster cooperation among practitioners to merge or form pools to reduce capital challenges and avoid leakages in premium through connivance of practitioners with foreign firms. With this, more premiums will be retained to increase the needed capacity to domesticate more oil and gas insurance in Nigeria.

Streszczenie:

Oil extraction in Nigeria has caused extensive environmental degradation and health problems in many Nigerian communities, particularly in the ecologically sensitive Niger Delta where nearly all of the oil extraction takes place. The reasons for this are complex and have roots in Nigeria’s colonial past. The Nigerian economy is largely reliant on its petroleum resources which, in conjunction with governmental corruption and high international demand for Nigerian oil, has created a system where environmental externalities are largely ignored. Multinational oil companies with little stake in the development and environment of Nigeria are responsible for most of the extraction projects and subsequent environmental damage. However, the Nigerian federal government has failed to effectively regulate these projects. Communities in the Niger Delta bear nearly all of the environmental burden of oil extraction, but see very little of the economic benefits. The main environmental impacts of oil extraction are oil spills, land use change, and gas flaring. Oil spills are very common in the Niger Delta. Cleanup efforts are often inadequate, resulting in loss of delicate ecosystems as well as fisheries and farmland. Large tracts of rainforest and mangrove ecosystems have been cleared or degraded by the oil extraction process. Nigeria flares more gas per barrel of oil extracted than any other country in the world, contributing to global warming and creating serious health hazards for communities located near gas flares. Diversification of the Nigerian economy would help to alleviate many of the factors that lead to environmental degradation, including the dependence of the government on oil revenues, high unemployment, and rampant oil theft. Curbing government corruption is also vital to effective regulation of oil extraction. International consumers can help Nigeria head towards a less petroleum-driven future through an increased awareness of the origins of their oil and pressure on the Nigerian federal government and the multinational oil companies to extract oil more conscientiously or even to discontinue oil extraction. But most importantly, the solution to Nigeria’s economic concerns must ultimately come from Nigerians as international influence has been a major contributor to the environmental degradation in the first place.

Streszczenie:

research analyses the impact of oil and gas exploration in the UK and Nigeria on the environment and settlements from the sustainability perspective, using a case study of an oil producing community (Uzere) in the Niger Delta region of Nigeria. This region is affected by oil and gas exploration activities, in terms of socio-economic, environmental and economic impacts. This state of affairs raises issues of environmental justice among the stakeholders. The research had two case study areas and included a total of 13 focus group, 86 questionnaires and 7 interviews. Analysis of this data showed that the oil and gas exploration activities in Nigeria are different from that in the UK. The empirical evidence equally suggests that the lack of technological advancement, management, legislation and corruption are strongly related to incidence of environmental impact during oil and gas exploration. The research further discusses the need to strive towards a balance between environmental sustainability and economic growth. Highlighting the fact and fiction of sustainable development and sustainability in the Niger delta and Nigerian, how Sustainable environment and growth can only be achieved through the integration of policies that connect the environment, the economy and the society. The novelty or contribution to knowledge of the research, developed a framework based on qualitative and quantitative findings. The resulting framework highlighted or proposed ways the Nigerian government can achieve its sustainable energy obligations based on the findings and the review of relevant literature, as well findings from methodology adopted. The proposed framework can be applied both theoretical and practical, this will not only protect the environment and people from the impacts of oil and gas exploration, but will also protect Nigeria crude oil resource saving lives and livelihoods over the coming years. Furthermore the research analyses a number of strategic initiatives, which can be adopted in Nigeria, taking lesson from the UK to achieve the balance between environmental sustainability and growth through the integration of policies, management, technology that connect the environment, society and economy.

Streszczenie:

The development of the offshore oil and gas industry has been going on for many decades with little thought of the consequences of its activities on the environment. However, in recent years, there has been a clamour by the international community to protect the marine environment from further degradation. Many global, regional and national laws have been made to that effect and some of these laws deal with the offshore oil and gas industry. One area that seems to be deficient in these laws is the management of wastes generated from operational activities of the offshore oil and gas industry especially during exploration and production. This is clearly illustrated by the inadequate regulation of offshore exploration and production (E&P) waste management in Nigeria

This thesis examined the efficacy of knowledge management based systems and best practices that could be used to address operational issues in Nigeria. The research focussed on the experiences of senior managers in Nigeria and the UK. The research employed both qualitative and quantitative methodologies to capture all the relevant experiences of senior managers. The findings revealed a number of knowledge management variables that either facilitated or limited the effectiveness of knowledge management based systems. These were synthesised into a framework capturing seven-well defined stages. All these steps emerged as being related; they are comprised of independent variables. These steps were found to comprise of knowledge management technology approaches, knowledge management people approaches, knowledge management strategies and value enhancing practices. The framework delineates the key variables that influence knowledge management based systems and highlights how value enhancing practices can be managed and implemented. The framework was developed from the key variables identified from the qualitative and quantitative analysis. Framework validation was by follow-up deliberations, which were conducted with managers in selected organisations in Nigeria and the UK. Reflecting on their experiences, the participants confirmed that the proposed knowledge management framework and its seven well-defined stages were central to the effectiveness of knowledge management in oil and gas projects. This thesis concludes by reiterating that the strategies proposed in this research cannot be expected to resolve all knowledge management operational issues in Nigeria. However, their use defines an approach that is superior to the traditional approaches typically adopted and consequently merits far wider application.

Streszczenie:

Environmental degradation and socioeconomic dilemma continue to stigmatize oil production in the Niger Delta of Nigeria. Sustainability programs of oil companies often determine the improvement of living conditions in the region. This explanatory qualitative case study, guided by systems thinking theory and sustainable value framework, explored practitioners' perceptions of sustainability programs to identify its impact on business and the host communities. The research question was designed to address how sustainability efforts of a single oil company in the Niger Delta contributed to the business performance and the livelihood of the local people. Research data were gathered from a sample of 20 experienced sustainability practitioners of the oil company, partnering nonprofit organizations, and community leaders through face-to-face semistructured interviews. Data were segmented and categorized. The data analysis process revealed several themes regarding the challenges and shortfalls of sustainability programs in the region. The oil company's understanding of sustainability as programs and projects focused on preserving resources for future generations was not evident in practice. Findings from the study suggested the need for improved inclusiveness of people in driving sustainability projects. Inclusive sustainability should enhance the oil company's contemplation mechanism to ensure eco-saving thinking and processes, which could result in improved quality of life and business performance in the region. The research findings underscore the need for oil multinational corporations (MNCs) to use a business lens in viewing sustainability to achieve sustainable value.

Abstract The importance of HSE in oil and gas activities especially in drilling operations cannot be overemphasized. Over the years, many systems of how to reduce and eliminate HSE challenges in our operations have been implemented. These systems keep changing to meet goal zero target. Despite the implementation and the published advances in HSE approaches and tools, HSE performance continues to be at least one incident above target which is Goal Zero. This paper is focused on identifying if the Best Value Approach (BVA) can be modified into a HSE leadership model to help HSE leaders, frontline barrier leaders with delivering GOAL ZERO. This paper specifically focuses on identifying the unique practice of the BVA that has generated a significant amount of documented high-performance results in the procurement of services and project management. This paper will translate this proven performance to HSE leadership. The paper will match this theory with a current HSE leadership practice of Assist and Assure in Shell. The aim, match theory to practice and then to theory and then produce a concept that will help HSE leaders optimise the implementation of the Assist and Assure Process.

Abstract Regulations for decommissioning are bound by international and domestic regulations. There are numerous decommissioning concepts to choose from, such as complete or partial removal, structure severance options which leave behind shell mounds and drill cuttings. However, in several international regulations there appears to be little clarity and/or opposing ideologies. Malaysia and Thailand have accessible resources for decommissioning legislation or guidelines in South East Asia. Nevertheless, they are differences in the regulations of these countries regarding the legal framework, the technical, financial and environmental framework. In this study, the feasibility of existing framework in decommissioning process of offshore installations or structures in Malaysia was studied and compared with international practices. Decision matrix analysis was used to systematically identify, analyse, and rate the performance of relationships between sets of values and information. Moreover, the scale of decommissioning activities over the next years, the data and information obtained were analysed using descriptive statistics approach. The results indicated that Thailand had the best decommissioning regulations because they have strict regulation in decommissioning. Most of the regulations covering the technical section are similar within all countries studied. Finally, recommendations given are from the aspects of frameworks on in-situ full or partial decommissioning, clarity on liabilities and residual risk management, financial security, residual risk funds, workflow optimisation, information management system, and waste management.

ABSTRACT Domestic utilization of natural gas in Nigeria is being hampered by the poor developments in the natural gas sector over the years, with low level of electricity (generation) consumption per capital, weak legal, commercial and regulatory framework amidst poor infrastructural developments in natural gas as compared to that which exists for oil. Nigeria ranks the second in gas flaring and shows low volumes of domestic gas utilization, consuming only about 11% out of the 8.25 billion cubic feet produced per day in 2014 despite its natural gas resource endowment. This paper examines the determinants of domestic utilization of natural gas in Nigeria from 1990-2013. It investigates its relationship as a function of price of natural gas, price of alternative fuels, foreign direct investment, volumes of gas flared, electricity generated from natural gas sources and per capital real GDP. Going further, it forecasts its likely growth rate for a short-term period, using an econometric methodology of ordinary least squares and an ARIMA model, it estimates the relationship between the variables and uses the historical trend to forecast into the future. The result of the study showed that the determinants jointly explain the pattern of domestic gas utilization in Nigeria by 98%. Individually, per capital real GDP, electricity generated from natural gas sources and changes in the volume of domestic utilization of natural gas was found to have a positive and significant effect on domestic gas utilization. Further, the forecast values show evidence of a slow but gradual increase in utilization pattern in the near future from 2015-2020. A best-case scenario of an increase of 0.15% and a worst-case scenario of a decrease of 0.14% was presented. In conclusion, having identified significant influences on domestic gas utilization patterns in Nigeria it is imperative that the government uses economic instrument to enhance the utilization patterns in Nigeria by improving economic activities and developing the power sector which shows significant influence in domestic natural gas utilization patterns.

Abstract Often, the production of oil and gas from underground reservoirs is accompanied by produced water which generally increases with time for a matured field, attributable to natural water encroachment, bottom water ingress, coning effect due to higher production rates, channeling effects, etc. This trend poses a production challenge with respect to increased OPEX cost and environmental considerations of treatment/handling and disposal of the produced water considering the late life performance characterized by low reward margins. Hence, produced water management solutions that reduce OPEX cost is key to extending the field life whilst ensuring a positive cash flow for the asset. SK field is located in the Swamp Area of the Niger Delta, with a capacity of 1.1Bcf gas plant supplying gas to a nearby LNG plant. Oil and gas production from the field is evacuated via the liquid and gas trunk lines respectively. Due to the incessant tampering with oil delivery lines and environmental impact of spillage, the condensate is spiked through the gas trunk line to the LNG plant. Largely, the water/effluent contained in the tank is evacuated through the liquid line. Based on the availability of the liquid line (ca. 40%-60%), the produced water is a constraint to gas production with estimated tank endurance time (ca. 8 days at 500MMscfd). This leads to creaming of gas production and indeed gas deferments due to produced water management, making it difficult to meet the contractual supply obligation to the LNG plant. An interim solution adopted was to barge the produced water to the oil and gas export terminal, with an associated OPEX cost of ca. US$2Mln/month. Upon further review of an alternate barging option, this option was considered too expensive, inefficient and unsustainable with inherent HSSE exposure. Therefore, a produced water re-injection project was scoped and executed as a viable alternative to produced water management. This option was supported by the Regulators as a preferred option for produced water management for the industry.

Abstract In order to properly meet up with the ever-increasing demand for petroleum products worldwide, it has become increasingly necessary to produce oil and gas fields more economically and efficiently. Waterflooding is currently the most widely used secondary recovery method to improve oil recovery after primary depletion. A crucial component required to conduct an efficient waterflooding operation is an optimal production setting, most especially with respect to the amount of water involved. This research work has been carried out to develop a model that can be used to maximize oil recovery and minimize water production with the least amount and number of waterflood variables in order to minimize the secondary recovery investment cost. The gradient-based approach to optimize the production and net present value (NPV) from a waterflood reservoir using the flow rates or bottom hole pressures of the production wells as the controlling factors with the use of smart well technology was applied. In this approach, a variant of the optimal switching time technique was used in the optimization process to equalize the arrival times of the waterfront at multiple producers, thereby increasing the cumulative oil production. The optimization procedure involved maximizing the objective function (NPV) by adjusting a set of manipulated variables (flow rates). The optimal pressure profile of the waterflood scenario that gave the maximum NPV was obtained as the solution to the waterflood problem. The proposed optimization methodology was applied to a waterflood process carried out on a reservoir field developed by a five-spot recovery design in the Niger Delta area of Nigeria, which was used as a case study. The forward run was carried out with a commercial reservoir oil simulator. The results of the waterflood optimization revealed that an increase in the net present value of up to 9.7% and an increase in cumulative production of up to 30% from the base case could be achieved.

Abstract In the Oil and Gas Industry, price disparity between Premium Motor Spirit (PMS), Automotive Gas Oil (AGO), and Dual Purpose Kerosene (DPK), often leads to adulteration of these petroleum products by marketers for monetary gains. Adulteration is the illegal introduction of a foreign undesirable substance to a substrate which affects the quality of the substrate. Adulteration of petroleum products are difficult to detect at Point of Sale (POS) terminals. Current methods for adulteration detection are time-consuming, require specialized equipment and experienced technicians to operate them, and cannot be used at POS terminals. Gaseous Vapor Technique (GVE) is an innovative adulteration detection technique that can be employed at POS terminals and the PePVEAT device utilized in this study is the first portable electronic device that performs GVE on petroleum products. GVE testing was performed on pure 1 L samples of PMS, AGO, and DPK obtained from the Nigerian National Petroleum Corporation (NNPC) using PePVEAT. The results obtained from GVE analysis of AGO, PMS, and DPK showed that the three petroleum products exhibited unique and varying chemical characteristics during GVE. AGO gives off its peak emissions between 10-20 seconds from test onset, DPK gives off its peak emissions between 10-30 seconds from test onset, and PMS gives off its peak emissions between 50-70 seconds from test onset. AGO emits 17.52-46.58 ppm of methane, 5.35-11.93 ppm of LPG, 35.51-84.6 ppm of butane, and 10.38-69.86 ppm of toluene. PMS emits 92,063.67-152,168.18 ppm of methane, 301.035-573.61 ppm of LPG, 2210.89-3424.94 ppm of butane, and 1983.02-7187.29 ppm of toluene. DPK emits 27.13-62.14 ppm of methane, 20.2-74.1 ppm of LPG, 120.41-1635.85 ppm of butane, and 1159.75- 1633.09 ppm of toluene. These variations in timing and concentrations of emissions shows that GVE can be utilized to detect and distinguish between AGO, PMS and DPK. The results obtained from GVE analysis of AGO, PMS, and DPK showed that Since PMS, AGO and DPK, each have unique chemical emissions during GVE, as was demonstrated in this paper, it is possible that GVE can be utilized to detect the adulterations of PMS with AGO and the adulteration of AGO with DPK. Future work involves investigating the ability of GVE to detect AGO-adulterated PMS, DPK-adulterated AGO, DPK-adulterated PMS, AGO-adulterated DPK,and PMS-adulterated DPK. The degree and percentage of adulteration that can be detected using the GVE technique will also be examined.

Abstract Life-saving rules (LSRs) are a set of defined rules that support and complement general site-specific safety rules and procedures (SRPs). LSRs are popular in the oil & gas (O&G) industry and are part of the safety management system framework designed to prevent incidents in the workplace. Complying with LSRs ensures its intent of incident prevention, drives the goal of creating decent work, economic growth and sustainable development. With the continuum of incidents in the industry, total compliance with LSRs and SRPs still remains a mirage. Even though the introduction of LSRs in the O&G caused a paradigm shift from fair to better safety performance, incident investigations continue to unveil cases of violations/non-compliance. In the space of continuous improvement, it becomes expedient to determine possible causes of these LSRs and SRPs non-compliance, with a view to nipping the causal factors in the bud. A descriptive cross-sectional study was conducted to determine the factors affecting the level of workers compliance with IOGP LSRs in selected O&G companies operating in Delta State, Nigeria. The research recruited 317 sharp end workers and selected leaders, through a multistage sampling technique. A semi-structured, self-administered questionnaire was used as instrument for data collection. The study in its findings was able to elicit numerous compliance determinants arising from socio-demography, occupational and organisational factors. These factors are barriers to strengthen if the goal of total compliance and zero incident must be achieved in the workplace. The study recommends that management should comply with Thomas Legge's aphorisms 1 & 4 on SRPs and design training programmes for employees to be imparted with requisite knowledge needed for compliance, commit to safety and lead a positive safety culture to drive continuous improvement. Furthermore, there is the need to pursue total compliance with LSRs, SRPs and any site-specific safety rules to achieve zero incidents in the O&G industry.

Abstract Sustained Annulus Pressure (SAP) is a common production constraint in the oil and gas industry, it is usually caused by impaired seal Integrity within the wellbore system resulting in barrier failures. In peculiar scenarios the thermal expansion creates pressure build-up in the annulus as well which can equally impair the integrity of the wellbore. In this paper the results of downhole and surface pressure monitoring surveys are presented, the objectives aim at determination of both downhole leaks and verification the influence of thermal expansion into a wellbore system integrity in a field located onshore Niger Delta. SAP in a producing well was earlier recorded during routine annular pressure monitoring in 2017 during the production rate increase by changing the bean size from 18/64" to 24/64". Initial diagnostics observed pointed towards SAP resulting from a possible downhole seal integrity issue leading to a leak to the surface. While putting the well on stream with current bean size and the pressure regime for both THP and CHP was observed. Pressure with time analysis showed annulus pressure builds up rapidly while flowing and bleeds off within 30 min from 700 psi to 0 psi when well shut in. Downhole logging and sensitive passive acoustic monitoring was conducted, the survey aimed to detect barrier failures by capturing its acoustic leak patterns under shut-in and bleeding off condition. Considering the suspected leak behaviour, the data acquisition included the procedure to build up the annulus pressure by flowing the well and monitoring the annulus discharge. Integrity logs survey and passive acoustic monitoring confirmed there were no downhole failures and after several bleed-offs when Tubing choke was beaned down to 18/64" no annulus pressure build-up was observed from the Well head gauge on the Casing head confirming the source of the sustained annulus pressure is driven by the temperature expansion of the annulus fluid. Remedial action and recommendation after Simulation were to de-risk the well at a controlled bean size to mitigate SAP and optimally flow the well.
