Abstract A super deep well was drilled in 1999-2000 to test the Pre- Khuff and Jurassic formations of Unayzah, Marrat and Najmah-Sargelu. The Unayzah formation had never been tested in North Kuwait before, therefore meticulous planning was required to successfully test this unknown HP-HT formation. ...
Abstract Kazakhstan based oil & gas companies recover approximately 2,000 to 3,000 metric tons per day of elemental sulfur from their product streams (approximately 500 tons of elemental sulfur is recovered for every 100,000 barrels of extracted petroleum in Kazakhstan). The bulk of the sulfur is recovered ...
Abstract This paper describes a material derived from natural sources that can be used to crosslink a variety of 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. For ...
Abstract Optimising is a term implying accomplishment of a desired objective at lowest cost through use of the most effective procedures. When optimizing drilling procedures, engineers ordinarily think in terms of factors affecting rate of penetration. These factors are bit weight and rotary speed, ...
Abstract This paper describes the development, design, lab and field testing of a new generation rotary shouldered connection for BHA components.Originally pursued to enable data transmission through the BHA, this new connection further provides a dramatic increase in fatigue resistance to cyclic loads.Additional ...
This paper was prepared for presentation at the 1999 SPE Asia Pacific Oil and Gas Conference and Exhibition held in Jakarta, Indonesia, 20-22 April 1999.
Abstract Produced waters from oil and gas drilling operations are typically very saline, and may cause acute toxicity to marine organisms due to osmotic imbalances as well as to an excess or deficiency of specific common ions. In order to better understand the relationship between toxicity and ion ...
Abstract In 1998, Schlumberger and Shell jointly launched a project to prove theconcept and economic viability of Dynamic Reservoir Drainage Imaging. The goalwas to provide a time-lapse monitoring of water saturation, allowing anevaluation of drainage efficiency in oil and gas reservoirs. To achieve ...
Abstract Worldwide demand for energy has forced the energy services industry to increase process efficiency and create innovative new methods of fracture stimulation optimization. Pinpoint fracturing methods represent a divergence from conventional fracture stimulation methods, which provide minimal ...
Abstract Traditional rigless plug-and-abandonment (P&A) operations involve time-consuming methods that can potentially be detrimental to personnel, assets, and the environment. Rising costs, the heightened level of safety required in the Gulf of Mexico (GOM) and beyond, and the unpredictability ...
Introduction Located in the Emirate of Sharjah, United Arab Emirates, the Sajaa onshore gas field is a Thamama limestone reservoir ranging from 11,000 to 13,000 feet true vertical depth (3350 to 3960 meters true vertical depth). The bottomhole temperature is in the 260 to 310 degrees Farenheight (126 ...
Abstract A major concern in the process of drilling is the high incidence and economic impact of lost time problems. In one study, it was shown that 75% of lost time incidents were associated with drilling mechanics problems. Obvious costs of poor drilling mechanics include lost rig time and damaged ...
Abstract This paper presents the first offshore applications, both in platform and subsea wells, of a multiple fracture creation process in openhole horizontal wells, previously applied in onshore scenarios. The applications had to overcome many challenges typical of workovers on mature field offshore ...
Abstract This paper will identify the increasingly stringent requirements of bit and mill design associated with small holes (particularly 2"") drilling what are considered large holes (>31/2""). This paper will focus to a greater extent on the bit requirements when drilling smaller holes, usually ...
Abstract Esso/Shell were awarded 4 exploration blocks in June 1993 in the North Irish Sea. This is an environmentally sensitive, nearshore area where several environmental groups were opposed to exploration taking place. The area is of ecological importance with a diverse wildlife and supports several ...
Abstract The Intermountain West Oil and Gas BMP Project (BMP Project) is a collaborative effort of the Natural Resources Law Center and its partners, including the Environmentally Friendly Drilling Program. The BMP Project has developed a comprehensive, free-access, searchable, web-based database of ...
Abstract Gel is considered to have an interesting potential for water shut off applications, especially in fields having natural shale barriers and large permeability variations and/or where reduction in tubing/casing diameter is not wanted. This paper describes a case study from the Statfjord Field ...
Abstract Subsea leakages from underwater production facilities may have significant environmental and economical consequences. There are a wide range of different technologies available for detection of subsea leakages, depending on the type of application and approach to leak detection. The two most ...
Abstract Traditional hydrate inhibitors such as methanol and glycols have been in use for many years, but at today's oil prices the demand for cheaper methods of inhibition will be required. The development of alternative, cost-effective and environmentally acceptable hydrate inhibitors is a technological ...
Abstract The Upper Cretaceous is a challenging drilling environment in Santos Basin, offshore Brazil. The lithology consists of highly intercalated layers of sandstone, siltstone and conglomerate from Santos and Jureia Formations. These formations are drilled vertically in 17 ½?? intermediate hole and ...
