Abstract In order to obtain the necessary Federal Government environmental clearance for exploration drilling in the Southern Davis Strait area the primary permit holders of this offshore region have in consultation with the Department of Indian and Northern Affairs undertaken a substantial environmental ...
Summary Culture-based methods of traditional microbiology applied to the microbiological processes involved in souring of oil fields and microbiologically influenced corrosion (MIC) pose a risk of yielding inadequate and contradictory results. Any cultivation step will almost certainly alter the population ...
Summary Laboratory and field research have developed better drilling and fracturig fluids for extremely water-sensitive gas-producing formations in western Canada. Other improved techniques include perforating in dry hole, stage fracturing using baffles and balls, higher rates, higher sand concentrations, ...
Summary Today's high operating costs demand a critical and thorough review of workover procedures and equipment. High-pressure gas leaks in both wellhead and tubing connections prompted an extensive workover program in the Arun field, North Sumatra. Mobil Oil Indonesia (MOI), contractor to Pertamina, ...
Summary. This paper deals with the planning, special equipment considerations, and operations necessary to convert 165 water injection wells to CO2 injectors that will function through at least the end of the century. The paper is divided into two parts: planning and engineering (wellhead, packer, and ...
Summary ConocoPhillips is developing the Magnolia field with a tension leg platform (TLP) in 4,674 ft of water at Garden Banks Block 783 in the Gulf of Mexico. The wells produce primarily from thick, fine-grained, Pleistocene reservoirs. Because of the long lengths of the producing reservoirs and large ...
Abstract The onshore Seria oil field, located in Brunei and operated by Brunei Shell Petroleum Co. (BSP), was discovered in 1929 and has produced over 1.1 billion barrels of oil. The field still has a large Near Field Exploration (NFE) portfolio of undeveloped hydrocarbon resources in reservoir blocks ...
Summary A drilling or a fishing jar is used in the bottomhole assembly (BHA) of a drillstring to free the string should it become stuck during the drilling operation. Because many expensive sensors are now incorporated in downhole tools, it is necessary to predict the damaging effect of jarring on ...
Abstract We analyzed moose tissue samples for extractable petroleum hydrocarbons (EPH), heavy metals and polycyclic hydrocarbons (PAH) and compared levels of concentration in tissues between two areas with noticeably different levels of oil and gas activity. Our treatment area (extensive oil and gas ...

Our treatment are (extensive oil and gas ...
Abstract We introduce an integrated technology for testing and controlling of high efficiency sub-divided zonal water injection in Daqing oilfield. The Oilfield is a heterogeneous multi-layer giant continental sandstone oilfield. After long-terms of water flooding, 95% of main pay zones have been ...
Summary Tropical wetlands and the presence of indigenous people with an ancient culture and a strong economic dependence on natural resources made the Pedernales field an environmental and socially sensitive location. BP's challenge was to work in this area without disrupting the lives of nearby settlements ...
Summary Since the passage of the Natl. Environmental Protection Act in 1970, the oil and gas industry has made tremendous progress in developing techniques, procedures, and less toxic materials for the protection of human health and the environment. The toxicity of drilling fluids and their disposal ...
Summary. This paper discusses the constructive use of resonant power transmission down the axial length of a stuck oilfield tubular for the purpose of extracting the tubular from inadvertent (e.g., stuck drillpipe or tubing) or purposeful (e.g., gravel-packed liners) confinement. Resonant and nonresonant ...
Drillstring failures can be prevented by drilling a straight, useful hole free of severe doglegs with larger-than-normal drillstring components. The maximum drill-collar diameters shown in the Lubinski tables in the IADC Drilling Manual, Sec. P1,1 for straight-hole drilling are essential for drilling ...
Summary Norman Augustine, CEO of Martin Marietta, in his book Augustine's Laws,1 observed that, ""Cost estimating is the first professional activity to make practical use of the mathematics of a complex number. It is easy to see the imaginary component in these estimations. The difficulty is in finding ...
Summary Concurrent drilling and production operations on offshore platforms increase the potential for blowouts and subsequent fires. platforms increase the potential for blowouts and subsequent fires. Present wellhead and Christmas tree designs address the potential Present wellhead and Christmas ...
Summary This paper describes a real-time, fiber-optic downhole video (DHV) system and its use as a diagnostic tool in solving production problems in Prudhoe Bay wells. Recent developments in lens preparation technology and advancements in the application of electro-fiber-optic cable have proved the ...
Abstract Proposals to construct multiple offshore liquefied natural gas terminals (LNG) in the United States that planned to use seawater as a heat source for vaporization of LNG have prompted assessments of the potential for entrainment of marine organisms in seawater intakes to impact fisheries. ...
Summary Maintaining well integrity for field life-cycle operations is a major factor that must be taken into account in the planning and execution of all well-engineering activities. Some legacy wells are not properly abandoned to prevent the contamination of secondary reservoirs or groundwater from ...
