The Wilmington Oil Field is a prolific petroleum field in Los Angeles County in southern California in the United States. Discovered in 1932, it is the third largest oil field in the United States in terms of cumulative oil production.〔Otott, George E. Jr & Clarke, Donald D. (1996) ("History of the Wilmington Field – 1986–1996" ). In AAPG Pacific Section, ''Old Oil Fields and New Life: A Visit to the Giants of the Los Angeles Basin'', pp. 17–22.〕 The field runs roughly southeast to northwest through the Los Angeles Basin, stretching from the middle of San Pedro Bay through Long Beach and east of the Palos Verdes Peninsula. The field originally contained approximately of reserves. As of 2002, approximately 90% of its original reserves had been recovered, leaving approximately . In 2013, the USGS estimated future potential production from the combined Wilmington-Belmont oilfield could be around . The offshore portion of the oil field is developed largely through wells drilled directionally from THUMS Islands, four artificial islands in Long Beach Harbor. ==Data== All figures are . Estimations as of 2013 (based off reserve estimates in 2008 and extraction from succeeding years, estimated through July). cumulative production – estimated reserves – annual production – producing wells – 1,428 (in 2008) estimated year of depletion (based on current rates and reserve estimates) – 2031 A 2013 USGS report estimates that the Wilmington-Belmont oilfield had Original oil-in-place of between 7600 and 12,000 million barrels of oil (MMBO), of which an additional 200 to 1950 MMBO could be produced, with 910 MMBO their best estimate of future production potential. 〔(Remaining Recoverable Petroleum in Ten Giant Oil Fields of the Los Angeles Basin, Southern California ), USGS, revised 2-2013〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wilmington Oil Field」の詳細全文を読む スポンサード リンク
