Abstract:
In recent years, China has made certain achievements in shallow sea petroleum geological exploration and development, but the exploration of deep water areas is still in the initial stage, and the water depth in the South China Sea is generally 500 to 2000 meters, which is a deep water operation area. Although China has made some progress in the field of deep-water development of petroleum technology research, but compared with the international advanced countries in marine science and technology, there is a large gap, in the international competition is at a disadvantage, marine research technology and equipment is relatively backward, deep-sea resources exploration and development capacity is insufficient, high-end technology to foreign dependence. In order to better develop China's deep-sea oil and gas resources, it is necessary to strengthen the development of drilling and completion technology in the oil industry drilling engineering. This paper briefly describes the research overview, technical difficulties, design principles and main contents of the completion technology in deepwater drilling and completion engineering. It is expected to have some significance for the development of deepwater oil and gas fields in China.

Abstract:
Magnetic materials in the drilling fluid used for drilling a petroleum well can significantly shield the Earth’s magnetic field as measured by magnetic sensors inside the drilling pipe. This has been shown to sometimes cause significant errors in the accuracy of borehole positioning using magnetic surveying. In this paper we present a physical approach for correcting the measured magnetic fields for such shielding. An explicit solution of the shielding problem is derived for the simplest case of a magnetic sensor on the axis of the borehole.

Abstract:
Record-high oil prices along with on-going development of infrastructure, increasing domestic demand and international LNG sales continued to drive significant investment in exploration in onshore and offshore Australia during 2007. These trends are reflected nationally by strong uptake of acreage and continued high levels of drilling activity and seismic acquisition. Overall, drilling and discovery trends were similar to 2006 which showed significant exploration activity focussed on proven hydrocarbon basins (Carnarvon, Browse, Perth and Cooper basins). Most petroleum discoveries made in 2007 were located within 10 to 15 km of existing fields. In terms of number of exploration wells, the offshore Carnarvon continued to dominate with over 20 new field wildcats drilled. Discoveries include a major deep-water gas find for BHP-Billiton at Thebe-1 on the outer Exmouth Plateau, Apache’s gas finds at Brunello–1, Julimar–1 and Julimar East–1, oil for Santos at Fletcher–1 and gas at Lady Nora–1 for Woodside. The Browse Basin saw a significant increase in drilling activity with some success. Exploration in the offshore southwest margin received a major boost with a series of shallow-water discoveries for ROC Oil in the Perth Basin with gas at Frankland–1 395and Perseverance–1 and gas and oil at Dunsborough–1. Onshore, the Cooper/Eromanga basins continued to experience the highest level of drilling activity and seismic acquisition. This activity resulted in numerous small to moderate oil discoveries for Santos, Beach Petroleum, Eagle Bay Resources, Stuart Petroleum and Victoria Petroleum. There were a few notable exceptions to near-field exploration in 2007 with several wildcats drilled in frontier regions including PetroHunter Energy and Sweetpea Petroleum’s Shanendoah–1 in the Georgina/Betaloo basins, Austin’s Gravestock–1 in the onshore Stansbury Basin and the onshore drilling campaign by ARC Energy in the Canning Basin. In Queensland, CSM exploration and discovery continued to experience strong positive growth underpinned by delivery to local markets.

Full text
Abstract:
The Timor Sea is the most remote and under-explored oil province in Australia. In order to compensate for the high exploration costs which result in frontier areas, new technology has been introduced by BHP Petroleum in order to increase drilling efficiency, assist in well evaluation and enhance the reliability of production technology. Examples of innovation and the importation of advanced techniques into the Timor Sea region are discussed. Advanced mud systems and PDC bit designs have been developed to aid the drilling of wells. Measurement While Drilling tools and tritium tracers have been used to enhance correlation and evaluation techniques. Equipment and procedures which emphasise the philosophy of reliability and longevity have been developed for sub-sea completions. These innovations have not only assisted with cost reduction, but have also enhanced BHP Petroleum's exploration and production success in the Timor Sea.

Abstract:
During drilling of petroleum or geothermal wells, unforeseen circumstances occasionally happen that require suspension of the operation. When the drilling fluid is left in a static condition, solid material like barite may settle out of the fluid. Consequently, the induced hydrostatic pressure that the fluid exerts onto the formation will be reduced, possibly leading to collapse of the borehole or influx of liquid or gas. A possible mitigation action is placement of a gel pill. This gel pill should preferably be able to let settled barite rest on top of it and still transmit the hydrostatic pressure to the well bottom. A bentonite-based gel pill is developed, preventing flow of higher density drilling fluid placed above it to bypass the gel pill. Its rheological behavior was characterized prior to functional testing. The designed gel pill develops sufficient gel structure to accommodate the settled barite. The performance of the gel was tested at vertical and 40° inclination from vertical. Both conventional settling and the Boycott effect were observed. The gel pill provided its intended functionality while barite was settling out of the drilling fluid on top of this gel pill. The barite was then resting on top of the gel pill. It is demonstrated that a purely viscous pill should not be used for separating a high density fluid from a lighter fluid underneath. However, a bentonite or laponite gel pill can be placed into a well for temporary prevention of such intermixing.

Abstract:
The Austin Chalk and Buda Limestone are commercial oil reservoirs along a 250-mile trend extending from Dimmit to Burleson counties, Texas. This south Texas Cretaceous hydrocarbon trend has been the focus during the past six decades of several ‘drilling booms’ which have delimited numerous large oil fields in fractured carbonate reservoirs adjacent to major faults. Data from wells drilled near two newly mapped faults in Caldwell County, Texas, indicate that, despite its maturely drilled status, the Austin-Buda trend has some future exploratory potential. Representative well histories reveal drilling and completion problems and economic risks that characterize the Austin-Buda trend.

Abstract:
In recent years, with the booming of petroleum industry and the continual reserve urgency of fossil oil, petroleum exploration technology in China is required to be a higher level. At present, with the improvement and development of computing technology and other technology, China's fossil oil exploration technology have been greatly improved, the oil field work has a stage improvement, petroleum exploration technology has also improved, Shaanxi Changqing Oilfield has also made remarkable progress, and it is worth mentioning that the three main techniques, the exploration technology of well logging technology, drilling technology and exploration technology, have made great progress on innovation through using new technologies. But it does not mean that the petroleum exploration technology has met the requirements of petroleum development. Petroleum exploration technology is insufficient and needs to be unremittingly combined with other techniques for its improvement and innovation. Based on this, this paper studies and analyzes the innovation of geological exploration technology in petroleum development process

Full text
Abstract:
Robert M. Kleinpell (1905-1986) brought new concepts into oil exploration in California in the late 1920s that enhanced oil recovery. He used basic biostratigraphic principles developed by Albert Oppel (1831-1865) in a study of the ammonite-bearing Jurassic successions in Europe to solve a challenge that faced California's petroleum industry in the 1920s. That challenge was how to recognize a specific stratigraphic position in a sequence of unseen and seemingly unfossiliferous, homogenous California Tertiary strata being perforated by oil-well drilling equipment and how to identify oil-bearing strata from well to well. Kleinpell's insightful use of relevant biostratigraphic principles led to recovery of many millions of barrels of petroleum from California's Tertiary stratigraphic succession. Despite considerable economic success, rarely have geologists outside California's petroleum industry recognized the significance of Kleinpell's economically rewarding application of scientific principle. Furthermore, rarely have American geologists noted the similarity between biostratigraphic practice of most Europeans and that of Kleinpell.

The generalization of the results of drilling, regional seismic exploration, core studies, well logging and well tests lead to identification of potential productive formations in the Jurassic-Cretaceous platform complex and in the Paleozoic basement. Some recommendations for further direction of exploration are proposed.

Abstract:
This is the first academic study of well costs and drilling times for Australia???s petroleum producing basins, both onshore and offshore. I analyse a substantial database of well times and costs sourced from government databases, industry and over 400 recent well completion reports. Three well phases are studied - Pre-Spud, Drilling and Completion. Relationships between well cost factors are considered, including phase time, phase cost, daily cost, rig day rate, well depth, basin, rig type, water depth, well direction, well objective (e.g. exploration), and type of completion (P&A or producer). Times and costs are analysed using scatter plots, frequency distributions, correlation and regression analyses. Drilling times are analysed for the period 1980 to 2004. Well time and variability in well time tend to increase exponentially with well depth. Technical Limits are defined for both onshore and offshore drilling times to indicate best performance. Well costs are analysed for the period 1996 to 2004. Well costs were relatively stable for this period. Long term increases in daily costs were offset to some extent by reductions in drilling times. Onshore regions studied include the Cooper/Eromanga, Surat/Bowen, Otway and Perth Basins. Offshore regions studied include the Carnarvon Basin shallow and deepwater, the Timor Sea and Victorian Basins. Correlations between regional well cost and well depth are usually high. Well costs are estimated based on well location, well depth, daily costs and type of completion. In 2003, the cost of exploration wells in Australia ranged from A$100,000 for shallow coal seam gas wells in the Surat/Bowen Basins to over A$50 million for the deepwater well Gnarlyknots-1 in the Great Australian Bight. Future well costs are expected to be substantially higher for some regions. This study proposes methods to index historical daily costs to future rig day rates as a means for estimating future well costs. Regional well cost models are particularly useful for the economic evaluation of CO2 storage sites which will require substantial numbers of petroleum-type wells.

Resumo: Os problemas na perfuração de poços de petróleo são responsáveis pela maior parte dos tempos não produtivos, elevando assim os custos diários das operações. Portanto, o estudo e o entendimento destes problemas contribuirá para a otimização da perfuração, melhorando assim as práticas ou mitigando os efeitos severos das anormalidades. O presente trabalho apresenta três procedimentos para identificação das causas dos problemas que poderão auxiliar o jovem profissional a caracterizar os mais variados problemas que ocorrem durante a perfuração de um poço. Neste escopo são abordadas apenas as ocorrências pré-classificadas como dificuldade de manobra, dificuldade de avanço, e prisão. O estudo usa dados dos boletins diários de perfuração dos poços, dados de mudlogging, dados obtidos por ferramentas de monitoramento contínuo da perfuração e outros dados como o fluido utilizado, a configuração da composição de fundo, o desgaste de broca, o gráfico do caliper, litologia e trajetória do poço. A caracterização dos problemas é feita mediante a identificação e associação de eventos que levam a formular hipóteses das prováveis causas dos problemas. Dois grupos de pesquisa (Unicamp e Genesis do Brasil) em engenharia de poço implementaram separadamente os procedimentos propostos. Os resultados foram coincidentes para a maioria trechos de poços marítimos de desenvolvimento analisados, o que atesta a eficácia dos procedimentos diagnósticos. Este estudo é importante para indústria, pois pode maximizar a eficiência na perfuração, através da minimização e/ou eliminação dos tempos não produtivos, responsáveis por avultadas perdas econômicas, além de permitir tornar mais robustas as ferramentas de acompanhamento, em tempo real, das operações de perfuração, na tomada de decisões e na melhoria do processo de planejamento de poço
Abstract: Drilling problems are accountable for the majority of the non productive times in the industry raising the daily operations costs. Therefore, the study and understanding of the problems will contribute to the drilling optimization, improving the practices or by mitigating their severe effects. The present work presents three procedures for identification of causes of drilling problems which can help the young professionals to characterize a wide range of problems that occur while drilling an oil well. In this scope they are studied only the problems pre-classified by occurrence as: problems in tripping, problem in drilling ahead and stuck pipe. The study uses data from the daily drilling reports, mudlogging data, on time monitoring tools data and mud data, Bottom Hole Assembly composition, bit wear report, caliper data, litology and well trajectory. The characterization of the problems is made by identification and association of the events that lead to formulate the hypotheses of the probable causes of the problems. Two research groups (Unicamp and Genesis do Brasil) in well engineering implemented separately the three proposed procedures. The results were coincident for the majority of the analyzed intervals of offshore development wells, demonstrating the efficacy of the proposed procedures. This work is important to the industry since it leads to the drilling efficiency maximization by minimization and/or elimination non productive times that are the main responsible for economic losses, beside the fact that these findings can be used to boost the capacity of the monitoring and logging tools as well as to support the on time decision making and to improve well planning process

Resumo: Na área de petróleo & gás, devido aos altos custos das sondas utilizados nas atividades de perfuração no mar, o aumento da velocidade de execução das operações torna-se imprescindível. A necessidade de se reduzir esses altos custos tem feito com que empresas de perfuração busquem métodos que permitam alcançar o objetivo almejado. Uma dessas formas é o aumento da taxa de penetração (ROP) da broca. Contudo, segundo pesquisas, os efeitos obtidos através dessa prática nem sempre tem resultado na redução dos custos operacionais. Embora pertinente essa constatação, não foram desenvolvidos estudos que pudessem dizer a real influência da taxa de penetração da broca sobre os custos de construção de poços. Essa deficiência motivou o desenvolvimento desta dissertação, que possui como objetivo estudar a influência da taxa de penetração da broca sobre os custos de construção de poços utilizando informações obtidas através da análise da análise de Boletins Diário de Perfuração, dados de mudlogging, entre outros. Para facilitar a avaliação desenvolveu-se um novo parâmetro de análise baseado no tradicional e difundido custo métrico da broca
Abstract: In the field of oil and gas, due to the high costs of rigs used in drilling activities, increasing the speed of operations execution becomes essential. The need to reduce these costs has made drilling companies seek methods to achieve the desired objective. One of those ways is to increase the rate of penetration (ROP) of the bit. However, according to surveys, the outcomes achieved through this practice have not always result in lower operating costs. Although relevant, studies that could tell the real influence of bit's penetration on the costs of well construction were not developed. This deficiency has motivated the development of this dissertation, which has as objective to study the influence of penetration rates on the well construction costs by using information obtained from daily drilling reports analysis, mudlogging data, among others. To facilitate the evaluation influence of bit's penetration on the costs of well construction has developed a new parameter of analysis based on the traditional and popular cost per foot

Resumo: Neste trabalho discute-se os desafios associados à atividade de perfuração de poços de petróleo através de formações afetadas pela presença de domos salinos. Domos salinos podem induzir grandes tensões nas formações subjacentes e adjacentes, impondo a necessidade de um planejamento específico para a perfuração e manutenção de poços de petróleo. Durante a perfuração, em frente à zonda de sal, há relatos de problemas de aprisionamento de coluna, dissolução de sal no fluido de perfuração, ocasionando a formação de batentes mecânicos e cavernas. Há ainda, nas formações que rodeiam um domo salino, devido à alterações no campo de tensões, problemas de instabilidade nas paredes do poço aberto e formação de zonas anormalmente prossurizadas. Após o revestimento do poço, há casos de colapso do revestimento. Para prever e mitigar os riscos associados à essa atividade é de fundamental importância o entendimento dos fenômenos físicos que o ocasionam. Com essa finalidade, foi feito um estudo à respeito de tais mecanismo físicos como fluência e instabilidade hidrodinâmica, mais especificamente a instabilidade de Rayleigh-Taylor. Desenvolveu-se, a partir de tal estudo, um modelo analítico para prever o desenvolvimento de um domo salino e discutiu-se a forma como este pode interferir em parâmetros importantes para a atividade de perfuração como, por exemplo, o campo de tensões nas formações adjacentes às camadas de sal
Abstract: In this present work are discussed the challenges associated with the drilling activities in oil wells through formations affected by the presence of salt domes. This geological structures can induce large stresses in the underlaying and adjacent formations, imposing the necessity of specific planning for drilling and maintenance of such oil wells. During drilling, facing the salt, there are reports of problems of stuck pipe, salt dissolution, forming mechanical stops and caves. There are still, in formations around a salt dome, due changes in the stress field, problems of well instability and abnormally pressure zones. After casing, there are cases of case collapse. To prevent and mitigate risks associated to this activity, is crucial understand the physical phenomena behind it. With such finality, was made an study related with such physical mechanisms, such hydrodynamic instability, specifically the Rayleigh-Taylor instability. Was developed, from this study, an analytical model to predict the salt dome development and was discussed the way such it can interfer in important paramenters related to the drilling activity as, for exemple, the tension field in the formation around the salt dome

Resumo: O cenário das perfurações de poços de petróleo vem mudando ao longo do tempo. Tanto pela necessidade do suprimento da demanda crescente por petróleo e gás quanto pela queda na produção de campos maduros, a perfuração de poços tem se deparado com ambientes mais agressivos a cada dia: maiores temperaturas, maiores pressões, maior afastamento em relação à costa e ambientes quimicamente mais hostis. A presença considerável de dióxido de carbono - CO2 - nos reservatórios aponta para uma maior preocupação na perfuração de poços em tais formações uma vez que, se esse componente adentra ao poço numa situação de kick, sua interação com a lama de perfuração pode alterar características importantes desse fluido, tais como: densidade, viscosidade e acidez. Este trabalho tem por objetivo investigar o comportamento PVT de sistemas contendo CO2 e líquidos com composição similar aos fluidos de perfuração à base de óleo: n-parafina pura e emulsão inversa. Foram realizados um estudo experimental de tais sistemas, uma simulação computacional, uma análise estatística dos dados obtidos para esse sistema com o intuito de avaliar as melhores correlações matemáticas para representação dos dados experimentais e aplicações de tais correlações em exemplos de controle de poço. Os resultados experimentais mostram que a simulação consegue reproduzir bem os dados experimentais (desvios de até 16%), apenas subestimando-os em frações molares de CO2 mais elevadas. Comparando os dados para o CO2, obtidos neste trabalho, com dados para o metano, obtidos da literatura, observa-se que o sistema contendo CO2 apresenta, dentre outras características, maior fator de formação de volume e solubilidade até 15 vezes maior que o sistema contendo metano. Por fim, ao examinar os exemplos de controle de poço, percebe-se que quanto maior é o teor de CO2 no sistema, maior é o valor do pit gain, tornando a presença de CO2 no sistema favorável à detecção do kick
Abstract: The scenario of oil and gas well drilling has been changing over the years. Not only because the need of supplying the increasing demand for petroleum and gas but also due to the decrease on the production of mature fields, well drilling has been constantly facing aggressive environments: higher temperatures, higher pressures, higher offshore distances and hazardous chemical environments. The presence of carbon dioxide - CO2 - on reservoirs leads to a concern on well drilling in these formations because the entrance of this gas into the well, in a kick situation, and its interaction with the drilling fluid can change important characteristics of this fluid such as: density, viscosity and acidity. This work aims to evaluate the PVT behavior of the systems containing CO2 and liquids similar to the ones used as base for oil-based drilling fluids: n-paraffin and inverse emulsion. An experimental study of these systems, a computational simulation, a statistical analysis of the data acquired aiming to evaluate the best mathematical correlations to represent these data and applications of these correlations were carried out. The experimental results show that the simulation can reproduce satisfactorily the experimental data (deviations up to 16%), only underestimating them at higher CO2 molar fractions. When comparing the data for CO2, obtained in this work, and the ones for methane, obtained from literature, it is possible to notice that the system containing CO2 has, among other characteristics, higher oil volume formation factor and solubility 15 times greater than the system containing methane. Finally, by examining well control examples, one can notice that the pit gain assumes higher values as the CO2 content increases making the presence of CO2 in the system favorable to kick detection

Abstract:
The need for energy and the associated economic benefits from the oil and gas deposits found mainly in the Niger Delta region of Nigeria necessitated the exploration and exploitation activities being carried out by the oil and gas Companies. However, these exploration and exploitation activities due to their unpredictable nature have a huge potential for environmental pollution as been experienced in the form of oil spills, gas flaring, irresponsible disposal of waste and several other activities that have resulted in the environmental degradation of the Niger Delta region. In the light of these, the Federal Government of Nigeria having experienced the consequences of pollution of the environment during the Koko Toxic Waste Dump incident in the then Bendel State in 1987 established a regulatory body tasked with the responsibility of harmonizing the economic interest from the oil and gas exploration and exploitation activities with the sustainability of the natural environment by developing well structured and articulated policies aimed at guiding the operations of the oil and gas operators, track their compliance and administer appropriate punitive measures for non compliance. However, this research work which is aimed at evaluating the impact of the environmental protection policies in upstream oil and gas activities in the Niger Delta region, involved the use of questionnaires and interviews. These questionnaires were completed by the management and staff of three major oil and gas companies operating within the area, the Department of Petroleum Resources and members of the Host communities. The interview was carried out to provide relevant feedback on their assessment of the impact made by the environmental protection policies on the upstream oil and gas activities in their operational areas/host communities. The study however concluded that “Although there is a regulatory body tasked with the responsibility to develop, implement and track compliance of the environmental protection policies in the upstream oil industry, the body is ineffective and as such the impact of the environmental protection policies is inadequate. Appropriate informed recommendations on the improvement strategies to the identified gaps that resulted in the unfavorable conditions were also provided.

Abstract:
Abstract X-Field is a mature offshore field located in the Sabah Basin, Malaysia. Two horizontal oil producers and one horizontal water injector was planned as part of the recent infill drilling campaign. As fields continue to mature, redevelopment projects often face both economical and technological challenges. Part of the redevelopment plan included the optimization of production and minimization of the residual/remaining attic oil in the reservoir. The horizontal well placement approach combined with drilling engineering concepts was synergized to handle the subsurface and drilling challenges. There are many key subsurface uncertainties when drilling horizontal wells, including but not limited to discontinuous sand bodies, lateral variations in sand thicknesses, multiple layering or sand/shale pockets, rapid structural changes, and fluid contact variation. In the planning stage, a systematic drilling engineering approach in managing drilling risks including complex anti-collision analysis contributed to successful drilling performance driven by "on-target" well placement execution. Selection of well placement technologies such as high definition multilayer-boundary mapping technology and wellbore imaging tool had enabled proactive geosteering to optimize the reservoir targets. This paper demonstrates the synergy of the drilling engineering and well placement technology selection, which was proven as a fit-for-purpose solution to deliver success to this horizontal well campaign in maximizing the production and injection potential.
