Tengizchevroil is a leading company that produces oil, gas and associated products that fuels the modern economy. Our history is closely interlinked with the rise of an independent Kazakhstan.
TCO maintains a leading position in the field of industrial safety in terms of such standard indicators as lost working days incidents and the rate of reported incidents.
TCO continues to achieve industry-leading safety results in standard industrial safety measurements such as Serious Incidents and Total Recordable Incidents.
The Contractor Health, Environment and Safety Management Process establishes clear accountabilities, ensures active engagement of contractors, and provides a consistent CHESM program to eliminate health, safety and environment (HSE) incidents and injuries involving contractors.
The requirements and activities included in CHESM process are focused on defining TCO expectations regarding contractor HSE performance, the qualification of contractors and the monitoring of contractor performance against expectations.
Contractors involved in activities presenting risks to workforce and process safety are subject to CHESM Qualification to evaluate HSE Management Systems and ensure adequate safeguards are in place and functioning before starting work at TCO Facilities.
TCO's work is guided by two key principles: do it safely or not at all and there is always time to do it right. Every employee of TCO and its Business Partner companies is responsible for making sure that work can be safely started. Each person has the right to temporarily suspend or completely stop any work if unsafe behavior or conditions are observed. The TCO Safe Work Practices Management Group, together with other teams, ensure that Occupational Safety and Health (OSH) guidelines and procedures are continuously implemented and maintained.
Tengizchevroil LLP (TCO) today announced its business performance results for 2025, highlighting the direct financial payments to Republic of Kazakhstan of $10.6 billion.
In January 2025, TCO reached a significant milestone at Future Growth Project - Wellhead Pressure Management Project (FGP-WPMP), by safely initiating production of crude oil at its new Third-Generation Plant (3GP), which was expected to expand Tengiz's crude oil output by an additional 12 million tons per annum. While TCO increased production of crude oil in 2025 to 39 million metric tonnes (311.3 million barrels).
Since 2000 total air emissions intensity has decreased by 78%.
Also, in 2025 TCO completed the phased implementation of automatic emissions monitoring systems (AEMS) and began real-time data transmission from TCO facilities to the relevant state authorities.
“We successfully and safely concluded 2025 with strong environmental and production results. These achievements are the outcome of the collective and coordinated efforts of the One TCO workforce. I would like to acknowledge not only the TCO and contractor organizations’ employees, but also to extend my sincere appreciation to our Partners, government authorities, and the public for their continued and unwavering support of the company’s operations for the benefits of the Republic of Kazakhstan”, - TCO General Director Billy Lacobie said.
Since 1993, TCO has made direct financial payments to Kazakhstan of about $212 billion, including taxes and royalties paid to the government, tariffs and fees paid to state-owned companies, profit distributions to the Kazakhstani shareholder, purchases of Kazakhstani goods and services and local employees’ salaries.
In 2025 company set a new record by achieving 71% of Kazakhstani Content (KC) spend performance driven by active engagement with domestic suppliers. Since 1993 TCO has invested about $52.3 billion on Kazakhstani goods and services. It is also worth mentioning that the Kazakhstani citizens now held 96% of positions in TCO compared to 50% in 1993.
TCO Deputy General Director, Kuanyshkerey Mukhtarov said: “TCO’s share of procurement in goods with Kazakhstani registered companies increased significantly from the previous year, reaching 15 per cent. And I would like to highlight the success stories of two local companies, PSI Energy and Karassay Machine-Building Plant, which successfully and safely completed the fabrication of two modular substations, each 38 meters long with modules weighing up to 92 tons. The project was delivered with a total of over 800,000 work hours and without a single lost-time incident. This is a great testament to the potential capabilities of our Kazakhstani companies.”
