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 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, ...
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 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, ...
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 ...
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 ...
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 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 ...
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 ...
Summary What is the most economical way to drill a well? It may be by using air, drilling fluids (other than air or gas), or a combination of both as the circulating medium. This decision requires a thorough study of an area before drilling. Regardless of the circulating medium used, crooked holes ...
Abstract Gas production from Alberta's Leduc-age reservoirs, which originally contained more than 400 ??109m3 OGIP, has and will continue to be significant. Estimating recoveries from these bottom- water drive pools has been difficult. Recoverable reserves are dependent upon both the trapped gas ...
Abstract This paper outlines the basic requirements for Environmental, Health and Safety (EH&S) Guidelines in field operations, and how they relate to the overall E,H&S management plan for an organization. The paper addresses the delivery of specific guidance to field personnel. The main segments of ...
Summary This paper focuses on prevention of well completion damage through proper choice of working fluids, pressure balance, and lost circulation material. Field pressure balance, and lost circulation material. Field applications are described, and damage prevention is advocated wherever possible. ...
Summary Sound well planning and carefully chosen drilling systems have proved successful in completing two high-angle holes through troublesome formations in the Gippsland basin offshore Victoria, Australia. Located about 60 miles [97 km] out in the Bass Strait, Mackerel Wells A-14 and A-16 set new ...
Summary This article describes a crosslinking material derived from natural sourcesthat can be used with a variety of polymers over a broad temperature range toproduce gels for conformance applications. Delayed crosslinked polymer systemshave been used for many years in conformance applications.For ...
Summary Wells with small liners occasionally require unique methods of drilling, completion, and reworking, especially deep-hole wells and wells with severe doglegs. Innovative drilling procedures were used successfully on two wells with those downhole conditions. On the first well, cement was drilled ...
Introduction This paper originally was in the form of an address to the Mining Society of Nova Scotia, 19th Annual Fall Meeting, Sydney, Nova Scotia, November 20, 1982. In this presentation, the paper was entitled “ Some North Sea Experiences With Offshore Hydrocarbon Developments ”. History The ...
A water surface acts not only as an optic mirror but also as an acoustic mirror. Echolocation calls emitted by bats at low heights above water are reflected away from the bat, and hence the background clutter is reduced. Moreover, targets on the surface create an enhanced echo. Here, we formally quantified ...
Abstract Operating Platong field in the Gulf of Thailand (GoT) is challenging because of the small compartmentalized reservoirs in the fluvial deposition environment. As the completion strategy has to be low cost in order to achieve the economic hurdle rate and the initial strategy is to develop to ...
Summary This paper describes a material derived from natural sources that can be used to crosslink a variety of acrylamide-based polymers over a broad temperature range to produce gels for conformance applications. Delayed crosslinked polymer systems have been used for many years in conformance applications. ...
