The Sakhalin-I ((ロシア語:Сахалин-1)) project, a sister project to Sakhalin-II, is a consortium to locate and produce oil and gas on Sakhalin Island and immediately offshore, in the Okhotsk Sea, from three fields: Chayvo, Odoptu, and Arkutun-Dagi.〔("Sakhalin-1: A New Frontier" ) - PennWell Custom Publishing (c/o of ExxonMobil)〕 In 1996, the consortium completed a production-sharing agreement between the Sakhalin-I consortium, the Russian Federation, and the Sakhalin government. The consortium is managed and operated by Exxon Neftegas Limited (ENL).〔 Since 2003, when the first Sakhalin-1 well was drilled, six of the world's 10 record-setting extended reach drilling wells have been drilled at the fields of the project, using the Yastreb rig. It has set multiple industry records for depth, rate of penetration and directional drilling. On 27 August 2012, Exxon Neftegas Ltd beat its previous record by completing Z-44 Chayvo well. This ERD well reached a measured total depth of , making it the longest well in the world.〔 ==Fields: Chayvo, Odoptu and Arkutun-Dagi== The three fields will be developed in this order: Chayvo, Odoptu, and Arkutun-Dagi. The total project is estimated to cost US$10–12 billion, making it the largest direct investment in Russia from foreign sources. It is also estimated that nearly 13,000 jobs will be created either directly or indirectly. Approximately $2.8 billion has already been spent, which helped lower unemployment and improved the tax base of the regional government. The fields are projected to yield of oil and of natural gas.〔 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「Sakhalin-I」の詳細全文を読む スポンサード リンク
