25 September, 2008 - Upstream OnLine - The Chevron-led Tengizchevroil consortium is set to almost double output capacity at Tengiz after finishing work on a major expansion at the Kazakhstan field. The expansion brings Tengizchevroil’s crude production capacity to 540,000 barrels of oil per day. The first phase of expansion, finished earlier this year, boosted capacity from about 310,000 bpd to 400,000 bpd. Chevron said sour gas injection (SGI) operations and the crude processing portion of the second generation plant (SGP) have been in service for several months, while the natural gas and sulphur processing portions of SGP were being completed and commissioned. The SGP’s full facilities now stabilise and sweeten crude, as well as separate and process natural gas into gas products and elemental sulphur. One-third of the produced sour gas is reinjected into the reservoir at high pressures to help preserve reservoir pressure. Chevron has a 50% sytake in Tengizchevroil. Its partners are KazMunaiGaz (20%), ExxonMobil (25%) and LUKArco (5%).
