23 January 2007 - Upstream onLine - Oil production at Kazakhstan's Tengiz oilfield fell to 13.3 million tonnes in 2006 from 13.6 million tonnes a year earlier, the field's operator said today. The Chevron-led Tengizchevroil (TCO) consortium gave no reason for the drop in output, which fell short of a target of 13.5 million tonnes. The company gave no forecast for 2007. Production is expected to nearly double after 2008 when the consortium has completed "second generation" improvements to its infrastructure and a gas re-injection project, Reuters reported. Chevron holds 50% in TCO, while national oil company KazMunaiGas has a 20% stake, ExxonMobil has 25% and Russia's Lukoil has 5%.
