Chevron CRUSH is an experimental ''in situ'' shale oil extraction technology to convert kerogen in oil shale to shale oil. The name stands for Chevron's Technology for the Recovery and Upgrading of Oil from Shale. It is developed jointly by Chevron Corporation and the Los Alamos National Laboratory.〔 〕 ==History== The Chevron CRUSH technology bases on the earlier ''in situ'' efforts. Sinclair Oil Corporation conducted an experiment using both natural and induced fractures to establish communication between wells and developing an ''in situ'' combustion process.〔〔 〕 Geokinetics, the Sandia National Laboratories, and the Laramie Energy Technology Center of the U.S. Department of Energy conducted field tests fracturing oil-shale formation by explosives and hydraulic fracturing technology.〔 Equity Oil Company, Continental Oil Company and the University of Akron studied the benefit of carbon dioxide as a carrier gas to facilitate a higher yield of shale oil.〔 Based on these works, Chevron Corporation and the Los Alamos National Laboratory started a cooperation in 2006 to improve the recovery of hydrocarbons from oil shale.〔 In 2006, the United States Department of the Interior issued a research, development and demonstration lease for Chevron's demonstration project on public lands in Colorado’s Piceance Basin.〔 〕 In February 2012, Chevron notified the Bureau of Land Management and the Department of Reclamation, Mining and Safety that it intends to divest this lease.〔 〕〔 〕 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「Chevron CRUSH」の詳細全文を読む スポンサード リンク
