この研究は水蒸気攻法で, オイルサンドからビチューメンを回収した後, さらにビチューメンを回収する方法として, 水蒸気にヘキサンや石油ベンジンのような軽質炭化水素を利用する方法について研究したものである。ここに報告したのは温度250°Cおよび300°Cの水蒸気に上記の溶剤を加え, その回収実験を行ったもので, 16の実験結果について, 水蒸気のみで10時間回収を行った場合, 始めの5時間は水蒸気で回収を行い, その回収がほぼ完了したと見られる5時間後から, ヘキサン, 石油ベンジンを水蒸気のほぼ2%程度混入した場合の回収率について検討した。この結果, 石油ベンジンを混入した場合はヘキサン混入の場合より大量のビチューメンを生産し, 300°Cの場合, その回収率は最大で56.6%となった。

The ACG Oil Field is situated offshore Azerbaijan, about 100-140 kilometers ESE of Baku, in water depth between 150 and 450 meters.The ACG megastructure is comprised of three culminations, namely the Deep Water Gunashli, Chirag and Azeri field. On 12 December 1994, the Azeri Government awarded the Production Sharing Agreement (“PSA”) to the Azerbaijan International Operating Company (“AIOC”). AIOC consists of nine international oil companies, including ITOCHU. The ACG PSA is for a period of thirty years and will expire in December, 2024.The ACG area is estimated to contain in excess of 5 billion barrels of recoverable reserves. The first production from Chirag platform started in November 1997. The start-up of production in Central Azeri, East and West Azeri and Deep Water Gunashli will be phased in from the beginning of Q1 2005 to 2008 across 4 producing platforms, 3 in Azeri (Phase 1 and Phase 2), and 1 in Deep Water Gunashli (Phase 3).The structure of the giant ACG Oil Field is a WNW to ESE trending, steep-dipping thrusted anticline. The main ACG reservoir is composed of Pliocene large river dominated lacustrine delta sandstone named as Pereriv and Balakhany sandstones.Currently, AIOC has drilled 18 wells on the Chirag 1 platform, of which 14 are producing wells and 4 are water injection wells. The production from the Pereriv sandstone is over 140,000 b/d crude oil.Phase 1 and 2 developments have been in the execution stages since September 2001 and September 2002, respectively. Phase 3 development starts in September 2004 and the total ACG field peak production rate is expected to exceed 1 million barrels a day. One of the export routes for such production will be the Baku-Tbilisi-Ceyhan (“BTC”) pipeline that is 1,768 kilometers in length and will be completed in early 2005.
