... available data for even the most visible of these giant fields to even make an educated guess at this important statistic. There is ample data showing that giant oilfields do ultimately peak and then begin to decline. All the giant fields of Texas are classic illustrations of this. Prudhoe Bay, Cusiana...

... at Prudhoe Bay, where CT drillingtechnology is considered to be a very valuable tool. Many of the existing wells at Prudhoe Bay could potentially benefit if replaced with horizontal completions. CT drilling offers the potential of achieving horizontal sidetracks without pulling the existing tubing...

... successful application in Prudhoe Bay. The authors will discuss field history and provide details and insights on operational procedures, applications and system limitations. INTRODUCTION The pursuit of technology to reduce production costs has changed traditional methods of well workover, maintenance...

... ABSTRACT During August 1982, a marine resistivity/induced polarization (IP) survey was undertaken in Prudhoe Bay, Alaska. Multi-electrode arrays with inter-electrode spacings of 10 metres and 25 metres were used to survey a total of 34 line kilometers. Apparent resistivity values were...

... operator in the Prudhoe Bay field and offshore rigs can be usedonshore, the Company suffers lost opportunity costs of up to $75,000 per day during the four to six weeks the rig sits idle offshore. A freight vehicle capable of providing reliable access to offshore drilling locations during the shoulder...

... Abstract In the Arctic ice is abundant and cheap, and therefore has long been considered as structural material for offshore drilling platforms. In February 1979 Exxon constructed an ice island 400 m in diameter and 10 m thick, in water 3.5 m deep, about 6 km north o£ Prudhoe Bay, Alaska...

... (manmade) gravel islands off the Sagavanirktok River delta in ten-feet and 18 feet water depths, 3) two sheet pile enclosed drill sites on natural barrier islands approximately 60 miles east of Prudhoe Bay, and 4) the development of two upland gravel sources, one near Prudhoe Bay and one near Pt. Thomson...

.... From 1980 to 1981, the AST-001 was tested at marshy areas several times. The AST-002 was brought to Prudhoe Bay in spring of 1981, and tested there until the end, of 1981 by sale running in as various ice conditions as possible, towing loaded sleds on ice road and snow-covered ice of sea area...

... season available in the Vicinity of Prudhoe Bay, the time consumptive nature of sand bag armoring becomes increasingly problematical as larger islands in deeper water depths are contemplated. An additional construction-related problem associated with individually-placed armor units is the difficulty...

... Abstract Sohio Petroleum Company constructed two artificial drilling islands in the Alaskan Beaufort Sea during the summer of 1980. Located northeast of Prudhoe Bay, Sag Delta No. 7 and No. 8 are situated in water depths of 11 and 7½ feet, respectively. Noteworthy aspects of theislands include...

... appear to be restricted to the area north and west of Prudhoe Bay. To the east and farther offshore, the gravel is covered by overconso1idated clay and silt or is ice-bonded. The hole north of Flaxman Island encountered very little sand and gravel for its entire depth of 300 feet. Soft organic silt...

... ABSTRACT The occurrence and properties of subsea permafrost near Prudhoe Bay, Alaska, were investigated by drilling and probing. Nine holes were drilled and 27 sites were probed with a cone penetrometer. The deepest drill hole was 65.1 m below the seabed, while a depth of 14.1 m was reached...

... hypotheses as to the origin: glacial deposits, grounding of sea ice and icebergs, sea ice melt deposits, surface permafrost features and mass movement. In 1968, a large ice island grounded and broke up of Prudhoe Bay and scattered remnants over a distance of 100 miles along the 15 fathom...

... ABSTRACT The underwater geometry of an ice island grounded off Prudhoe Bay, Alaska was mapped using a narrow beam sonar. Vertical section profiles of the submerged portion of the ice island were obtained by lowering a sonar transducer through the pack ice at eleven sites surrounding the ice...
