Prudhoe Bay is the largest oil field in North America with reserves of over 13 billion barrels of oil and condensate, one billion barrels of NGLs, and an expected 23 tcf of gas. However, Alaska lands in third place as the top oil producer in the nation, trailing behind Texas and North Dakota. The seeds for the conflict in 1965 with the firs t Prudhoe Bay lease sale, the separate oil and gas ownership came about mainly because of the complex geology of the Prudhoe Ba y field. See more » Alaska North Slope The Alaska North Slope is the region of the U.S. state of Alaska located on the northern slope of the Brooks Range along the coast of two marginal seas of the Arctic Ocean, the Chukchi Sea being on the western side of Point Barrow, and the Beaufort Sea on the eastern. The Prudhoe Bay field is located on the North Slope of Alaska, 400 kilometres north of the Arctic Circle. [1][2][3][4][5] The main Permo-Triassic reservoir is a thick deltaic high-quality sandstone deposit about 500 ft thick with porosities of 15 to 30% BV and permeabilities ranging from 50 to 3,000 md. Raven produces from the Ivishak and Sag River Formations and began production in 2005. This area produces significant amounts of conventional oil that are transported by pipeline to southern Alaska. It is located approximately 400km north of the Arctic Circle and approximately 1,046km away from Anchorage. Geoscience Training Center Cefoga Basic Geology for Oil Exploration Basic Geology for Oil Exploration 2. Geochemical data indicate the most important source rocks known at present are Cretaceous and Jurassic shales. Popular ... Stratigraphic oil and gas fields: classification, exploration methods, and case histories 1972 - American Association of Petroleum Geologists - Tulsa, Okla. Prudhoe Bay oil and gas field details. The 24/sup 0/ API crude is similar in type to that in the Permo-Triassic reservoirs in the Prudhoe Bay field; however, it is from the Lower Cretaceous Kuparuk Formation. The Prudhoe Bay field is located 650 miles north of Anchorage and 400 miles north of Fairbanks. This analysis suggests that most North Slope oil and gas was generated during Cretaceous time. The Prudhoe Bay area mainly contains crude oil from the middle to upper Triassic Shublik Formation, approximately 59% (MASTERSON, 2001). 41 Alaskan North Slope Geology, Volumes I and II, 1987 The Prudhoe Bay oil field is spread over approximately 213,543 acres on the Beaufort Sea coast, in the North Slope, Alaska. Statistics for the Greater Prudhoe Bay Field: Discovery well: Prudhoe Bay State #1; Discovery date: March 12, 1968; Production start: June 20, 1977; Total field area: 213,543 acres (864.18 km2) Oil production wells: 1114; Total capacity: 25 billion barrels (4.0×109 m3) Produced: 12 billion barrels (1.9×109 m3) as of March 28, 2013 The Raven oil pool lies beneath Niakuk and is also included in this analysis. The Kuparuk oil field is located on the Alaskan Arctic plain in the Colville-Prudhoe basin, 10 to 30 mi (16 to 48 km) west of the Prudhoe Bay field. The North Slope of Alaska is the location of the famous Prudhoe Bay Oil Field. Prudhoe Bay Oil Field is a large oil field on Alaska's North Slope. Prudhoe Bay oil field is a large oil field on Alaska's North Slope.It is the largest oil field in both the United States and in North America, covering 213,543 acres (86,418 ha) and originally containing approximately 25 billion barrels (4.0 × 10 9 m 3) of oil. INTRODUCTIONAs with all oil fields, development practices at Prudhoe Bay field on Alaska's North Slope ( Figure 1) have evolved as the field has matured. The field is situated less than two kilometres offshore in the Beaufort Sea, between the Prudhoe Bay and Endicott fields. Pump Station 1, the beginning of the Trans Alaska Pipeline, is located with in the perimeter of the Prudhoe Bay field. Dozens of development wells were drilled, topped with Christmas trees, and awaited the completion of the Trans-Alaska Pipeline in 1977. The Prudhoe Bay oil field: The largest oil discovery in the USA. Both fields are satellites of Prudhoe Bay. While not a household name to many Americans, the Prudhoe Bay Oil Field is integral to both the American economy and its energy independence. The Shublik Formation is a The oil and gas fields discovered in the PET-4 program and the presence of the supergiant Prudhoe Bay field certify its qualification as a major petro liferous basin. It is 1200 miles from the North Pole and 250 miles north of the Arctic Circle. The supergiant Prudhoe Bay field is the result of rich, thermally mature Cretaceous source beds spperposed on the truncated edges of a series of good reservoir beds. Additionally, oil from the Hue Shale and the Kingak Shale were added to create a mixture of oil types in the Prudhoe Bay field (Bird, 1994). WithFn the Reserve the unconfonity accounting for this superposition is apparently1 present on- Significant infill development drilling and EOR programs have raised present reserves estimates to more than 13 BSTB.
