Chevron's activities in Central Asia are the responsibility of its Eurasia Business Unit (EBU) headquartered in Almaty, Kazakhstan.

Chevron EBU's principal asset is the 50% shareholding in Tengizchevroil. Tengizchevroil, formed in April 1993 as a partnership between Chevron and Tengizmunaigas, owns and operates the Tengiz oil field in western Kazakhstan. Tengiz crude is blended with relatively small quantities of other grades and exported via the CPC pipeline as CPC Blend.

Chevron acts as Tengizchevroil's agent in marketing CPC Blend crude oil in international markets.
