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 (TCO) participated in the 3rd Annual Conference “KazDrilling: Upstream of Kazakhstan 2026,” which brought together representatives of government agencies, national companies, international investors, operators, oilfield service organizations, and industry experts to discuss key issues shaping the future of Kazakhstan’s oil and gas sector.
During the plenary session, TCO General Director William Lacobie emphasized that the future competitiveness of the oil and gas industry will depend not only on advanced technologies and operational excellence, but also on the ability of operators to develop local companies, strengthen the country’s industrial base, and create opportunities for Kazakhstani professionals.

“We are seeing tangible results from our efforts to advance Kazakhstani Content in drilling operations. The localization of chemical products, expanded collaboration with local manufacturers, and their successful qualification to provide highly specialized services demonstrate the growing capabilities of Kazakhstan’s industrial sector and its ability to meet the demanding requirements of the oil and gas industry,” said William Lacobie.
Since its founding, TCO’s cumulative spend with Kazakhstani suppliers has reached US$52.6 billion. In 2025 alone, the company procured approximately US$1.8 billion worth of goods and services from local suppliers. As a result, the share of Kazakhstani Content reached 71%, driven by increased procurement from domestic manufacturers.
Significant progress has also been achieved in the goods category. While the actual share of Kazakhstani Content in this category stood at 7% in 2024, it increased to 15% in 2025.
