The Heidrun oil field is an oil and gas field discovered in 1985 in the Norwegian sector of the Norwegian Sea, named after the goat Heiðrún from Norse mythology. The field lies West of Kristiansund. It has produced oil and gas since October 1995. In 2013, it produced 65,000 bbl of oil per day and 760 million cubic meters of natural gas.〔(Offshore Technology )〕 The crude oil is characterized as being naphthenic with 25.0 API (0.9043 g/cm3), 0.52% sulfur, and a high TAN (Total Acid Number) of 2.90. The Heidrun field is located on Haltenbanken in the Norwegian Sea at a depth of . The field has been developed with gas and water injection, using a floating concrete tension leg platform, installed over a subsea template with 58 well slots.〔Whitley, P.K., The Geology of Heidrun, 1992, in ''Giant Oil and Gas Fields of the Decade, 1978-1988'', AAPG Memoir 54, Halbouty, M.T., editor, Tulsa: American Association of Petroleum Geologists, ISBN 0891813330, pp. 383-406〕 The northern part of the field is developed with subsea facilities. ==Geology== The Cimmerian structure is a southwest-plunging horst block on the southwest flank of the Nordland ridge formed in the Late Jurassic-Early Cretaceous.〔Whitley, P.K., The Geology of Heidrun, 1992, in ''Giant Oil and Gas Fields of the Decade, 1978-1988'', AAPG Memoir 54, Halbouty, M.T., editor, Tulsa: American Association of Petroleum Geologists, ISBN 0891813330, pp. 383-406〕 Production is from Jurassic Fangst Group sandstones with the Upper Jurassic Spekk Formation shales being the petroleum source and Cretaceous shales forming the seal.〔Whitley, P.K., The Geology of Heidrun, 1992, in ''Giant Oil and Gas Fields of the Decade, 1978-1988'', AAPG Memoir 54, Halbouty, M.T., editor, Tulsa: American Association of Petroleum Geologists, ISBN 0891813330, pp. 383-406〕 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「Heidrun oil field」の詳細全文を読む スポンサード リンク
