Summary In May 1990, the Norwegian Oil Industry Assn., Oljeindustriens Landsforening (OLF), commissioned a survey of chemical use in E&P activities in the North Sea. Ten operating companies and six chemical suppliers provided data on the specific types and quantities of chemicals used in their ...
Abstract The word ""integrity??, is defined as: ""the state of being whole, complete and entire, in an undiminished or unbroken condition??. Well Integrity Remediation, therefore, is maintenance of well quality to insure such totality and undiminished condition. Well integrity has received a significant ...
This paper (SPE 50981) was revised for publication from paper SPE 37748, first presented at the 1997 SPE Middle East Oil Show held in Bahrain, 15-18 March. Original manuscript received for review 19 March 1997. Revised manuscript received 19 May 1998. Paper peer approved 26 May 1998. Summary The Athel ...
Abstract The United States Department of Energy (DOE) seeks to validate the feasibility of injecting, storing and monitoring CO2 in the subsurface (geologic storage) as an approach to mitigate atmospheric emissions of CO2. In an effort to promote the development of a framework and the infrastructure ...
Summary Drilling ultradeep (UD) wells places significant requirements on the drillstring. Lengthy drillstrings lead to high tensile loads, which can lead to slip crushing of the drillstring; hoisting capacity issues; and drillpipe collapse capacity concerns at the blowout preventer (BOP). BOP shear ...
Summary The objectives of this investigation were to document the physicochemicaland aquatic toxicological quality of a physicochemical and aquatictoxicological quality of a ""beneficial-use"" produced-water dischargeand its effect on a receiving stream in Wyoming. Fish and water-flea survival,growth, ...
Original SPE manuscript received for review June 10, 1995. Revised manuscript received July 24, 1995. Paper peer approved July 26, 1995. Paper (SPE 29370) first presented at the 1995 SPE/IADC Drilling Conference held in Amsterdam, Feb. 28-March 2. Journal of Petroleum Technology, October 1995. Summary Far ...
Summary The Eunice Monument South Unit (EMSU) waterflood project is a large-scale (354 wells) example of implementing a waterflood in a highly depleted reservoir. Because of the maturity of this field ( greater than 50 years), several problems were encountered, such as drilling depleted intervals, ...
Summary Placing properly balanced cement plugs in wells has been a serious problem to the drilling industry for decades. The cement plug is rarely found at the desired depth. Because of the fact that the cement slurry usually is more dense than the well fluid, the cement plugs are found deeper than ...
Summary The national oil company of Trinidad and Tobago (Petrotrin) has more than 5,000 idle wells. The company initiated a procedure for leasing these idle wells to small independent operators in July 1989 through a program known as the ""lease operatorship"" program. This paper reviews the status ...
Summary The reuse of existing well bores is a cost-saving technique used by oil and gas producers in mature fields. This process usually requires the removal of tubing and packers to allow the well to be deepened or sidetracked. The tubing removal process is often made difficult when the tubing is ...
Summary This paper chronicles the design analysis performed to drill the Gulf of Mexico's deepest well. With small-diameter casing cemented in the hole, slimhole drilling plans for the record depth well were generated. The short fuse project required an atypical slimhole drillstring design to select ...
Summary This paper discusses the evolution of the global and regional Regulatory Regime for the decommissioning of disused oil and gas production platforms and other installations. The last part of this paper puts the regulatory aspects of the issue discussed into context. Introduction In June ...
Summary Low-dosage hydrate inhibitors (LDHIs) have been actively investigated for more than a decade in both academia and the petroleum industry. The promise of LDHIs has been to provide a viable alternative to thermodynamic inhibitors, such as methanol and glycol. Inevitably, the journey of LDHIs ...
Summary An oil field in central Saudi Arabia produces super-light crude from a sandstone reservoir. The formation contains up to 7.0 wt% authigenic clays dominated by kaolinite and illite/montmorillonite mixed layer clays. To mitigate sand production and improve well productivity, a frac pack stimulation ...
Summary Mercury has been known to be a trace contaminant in natural gas and condensate produced from Unocal Thailand's operations in the Gulf of Thailand since 1985. It has been detected in well streams, produced formation water, and also in solid waste. Mercury is recovered from process vessels, ...
Summary. Recently developed horizontal-drilling techniques have been applied in the Spraberry trend area in Midland County, TX. The desired application includes drilling horizontally at a right angle to the naturally occurring vertical fractures in one of three Spraberry zones. The result was 1,180 ...
Summary This paper discusses current water quality assessment methods and some of the parameters that can affect the suitability of North Sea water as an injection fluid. Also included are general comments on the North Sea and its biomass. Examples are drawn from tests carried out during the commissioning ...
Summary A new liquid thickening agent has been developed for controlling fluid loss of clear brines. This control is of critical concern during the completion or workover of an oil, gas, or service well. Many clear brines are expensive (up to $800/bbl for some concentrations). The loss of these fluids ...
Overview Every day in the oil and gas industry, cutting-edge technology is driven—sometimes inch by inch and occasionally in great leaps forward. Commitments are taken to make the seemingly impossible, possible, to provide solutions to the challenges of tomorrow. Advanced technology is used, not for ...
