JACOS is a subsidiary of JAPEX (Japan Petroleum Exploration Company Limited), which owns 86% share in the company. Minor shareholders are Inpex (5%), Mitsui (4%), and Japanese financial institutions (3%).〔 〕 ==History== JACOS started oil sands activities in the Athabasca area in 1978 on leases held by Petro-Canada, Canadian Occidental (Nexen) and Imperial Oil to form the PCEJ group.〔 〕 It was the first Asian-owned oil company to exploit the Athabasca oil sands.〔 JACOS and its partners experimented with a cyclic steam stimulation (CSS) pilot project on the Hangingstone Lease from 1984 to 1994.〔 〕 In 1992, JACOS parent company JAPEX participated in the Alberta Oil Sands Technology and Research Authority (AOSTRA) steam-assisted gravity drainage (SAGD) pilot experiments at the underground test facility (UTF) site.〔 〕 With the positive results from the UTF project, JACOS decided to further pursue SAGD technology at the Hangingstone site. A 3-phase demonstration project was designed and constructed with the first phase becoming operational in 1999.〔 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「JACOS」の詳細全文を読む スポンサード リンク
