Deep beneath the western Kazakhstan steppe is a giant reservoir known as the Tengiz Field, where the oil column measures an incredible 1 mile (1.6 km) across. With a surface area more than four times that of Paris, France, Tengiz ranks as the world’s deepest producing supergiant oil field and the largest single-trap producing reservoir in existence. Nearby is another world-class reservoir called the Korolev Field. Chevron holds a 50 percent interest in Tengizchevroil (TCO), which operates the two fields.

Today, the fields' yearly output could satisfy the annual oil demand of entire nations. Net daily production in 2019 (Chevron share) averaged 290,000 barrels of crude oil, 419 million cubic feet of natural gas and 21,000 barrels of natural gas liquids.

综合未来增长项目 - 井口压力管理项目(FGP-WPMP)旨在进一步从Tengiz水库中进一步增加每日产量,并最大限度地提高资源的最终恢复。


In parallel, the WPMP maximizes the value of existing TCO facilities by extending the production plateau and keeping existing plants producing at full capacity. First oil is planned for 2022.

Tengiz and Korolev are located about 6 miles (10 km) east of the Caspian Sea.



Since the start of the FGP-WPMP, we've worked to identify and develop viable, sustainable opportunities to maximize the use of Kazakhstani goods and services. One way we're doing this is through the TCO Small and Medium Business Loan Program. Since the start of this TCO program, we've provided $9 million in interest-free loans to entrepreneurs and small businesses, like MontazhSpetsStroy JSC (MSS), Kazakhstan.






“Energy development has been critical in generating Kazakhstan’s growth and prosperity. At Chevron, we are very proud to play a supporting role in generating Kazakhstan’s success and its goal to become a nation of global prominence.”

FGP-WPMP can be described as the third generation in a two-decade-long process that has steadily increased production from Tengiz. FGP-WPMP will reinject all of the naturally occurring hydrogen sulfide, or “sour gas,” produced by oil processing, maintaining pressure in the reservoir. TCO is developing FGP-WPMP with a demonstrated commitment to local (Kazakhstani) content, worker safety, environmental and social performance.

The project’s approach to construction of the FGP-WPMP facilities is to use large, fabricated equipment blocks called modules. The main FGP-WPMP equipment will be fabricated in South Korea, Kazakhstan and Italy, and pre-assembled for transportation to Tengiz for final assembly and hook-up.

Did you know? TCO is the leading energy producer in Kazakhstan, contributing about 30 percent of Kazakhstan’s total oil and gas output.

“The Tengizchevroil joint venture was founded in 1993 with the objectives of delivering stable, reliable production from the Tengiz oil field while steadily increasing our national workforce and our use of Kazakhstani goods and services.”

当TCO成立于1993年的Tengiz领域的运营商时,该领域的持续运营包括相关天然气的常规燃烧(天然存在的气体,不用于商业销售)。金沙博彩从那时起,TCO已经开始了一系列主要资本项目,最终消除了常规燃烧。此类投资使TCO能够以自2000年以来减少85%的全天然气燃烧量;将气体利用率提高到98%以上;并减少每吨油产生的总空气排放量为73% - 均为每年提高159%的原油量。

Since 2000, TCO has invested more than $3 billion on projects that have reduced its environmental impact.
