Chevron Corporation announced today that its 50%-owned affiliate Tengizchevroil LLP (TCO) has started oil production at its Future Growth Project (FGP) located at the Tengiz oil field in Kazakhstan.FGP is the third processing plant in operation at the Tengiz oil field, which expands sour gas injection capability and is expected to ramp up output to one million barrels of oil equivalent per day.

This milestone follows the completion of the Wellhead Pressure Management Project (WPMP) in 2024, which is designed to optimize the field and processing plants.

The FGP expansion aims to increase crude oil production by 260,000 barrels per day at full capacity.

The Tengiz oil field, located in western Kazakhstan, ranks as the world’s deepest producing supergiant oil field and the largest single-trap producing reservoir in existence. The oil column measures 1 mile (1.6 km) in thickness and lies between 2.5–3.7 miles (4–6 km) in depth.

Estimated oil in place in the Tengiz Field is 3.2 billion tonnes (25.5 billion barrels), with 200 million tonnes (1.6 billion barrels) in the Korolev Field. Total recoverable crude oil between the two fields is estimated at 890 million to 1.3 billion tonnes (7.1 billion to 10.9 billion barrels).

The FGP and WPMP projects together installed power systems at Tengiz with five Frame 9 gas turbine generators, added four large compression trains with additional pumping capacity, installed a new centralized control center and enhanced sour gas handling and reinjection to the field for long-term pressure maintenance.

Tengizchevroil LLP is a Kazakhstani partnership owned by Chevron, 50%; KazMunayGas, 20%; ExxonMobil, 25%; and Lukoil, 5%.
