Tengizchevroil is a joint venture between Chevron (50 % share in the consortium), ExxonMobil (25 % share), KazMunayGas (20 % share) and LukArco (5 % share). The joint venture was formed in April 1993, when the Kazakh government granted an exclusive 40-year right to Tengizchevroil (TCO) to develop the Tengiz and Korolevskoye oil fields located in the north-eastern reaches of the Caspian Sea in Kazakhstan.

From a two-company joint venture in 1993 (between Kazakh state oil company Kazakhoil, now KazMunayGas, and the US company Chevron) Tengizchevroil expanded in 1996-97 into a four company consortium: ExxonMobil Kazakhstan Ventures, an ExxonMobil subsidiary, and LukArco, a joint venture between Lukoil of Russia and Atlantic Richfield (Arco) of the USA, acquired 25 % and 5% respectively. Since 2000 has also the British BP a part in it, since BP merged with Arco and took its share in LukArco.
