ASTANA: Chevron-led venture Tengizchevroil's (TCO), Kazakhstan's largest oil producer, output is expected to total 26.7 million tonnes in 2015, unchanged from last year, Kazakh Energy Minister Vladimir Shkolnik said on Wednesday.

TCO, which develops the giant onshore Tengiz oilfield in western Kazakhstan, is expected to achieve a production volume of 38 million tonnes a year by 2021 owing to its current expansion programme, Shkolnik told a government meeting.
