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) participated in the XIII Kazakhstan Machinery Forum, one of the country’s key industry platforms bringing together representatives of government authorities, industrial companies, and the machinery sector.
During an IMBC panel session, TCO shared its progress in advancing Kazakhstani Content in oil and gas machinery manufacturing and highlighted the role of local producers within the company’s supply chain.
According to the results of last year, output in the manufacturing sector amounted to KZT 30.6 trillion, exceeding the performance of the extractive industry for the third consecutive year. Acting on the President’s instructions, the Government is pursuing a balanced industrial policy with a focus on localization and support for companies establishing production facilities in the Republic of Kazakhstan, said Prime Minister of the Republic of Kazakhstan Olzhas Bektenov. 
As part of the business program, Kuanyshkerey Mukhtarov, Deputy General Director of TCO, spoke about the company’s approaches to advancing Kazakhstani Content, enhancing the competitiveness of local manufacturers, and integrating international quality standards across the supply chain. Particular attention was given to the role of the International Center for Development of Oil and Gas Machinery (IMBC) as one of the key partners in qualifying Kazakhstani enterprises and expanding their participation in oil and gas projects.
“Advancing Kazakhstani Content is one of our key priorities. We consistently expand the participation of domestic manufacturers in TCO’s supply chain, with a strong focus on enhancing their production and technological capabilities, as well as ensuring compliance with international requirements and standards of the oil and gas industry. In this process, IMBC plays an important role as a platform supporting supplier qualification and strengthening the capacity of local manufacturers,” said Kuanyshkerey Mukhtarov.
Over the past three decades, TCO has created hundreds of thousands of jobs and actively procured Kazakhstani goods and services, stimulating economic activity not only in the Atyrau Region but across the country. In 2025 alone, TCO purchased goods and services from Kazakhstani suppliers totaling approximately USD 1.8 billion. These funds were directed toward products and services delivered in Kazakhstan and meeting international quality standards. This approach supports technology localization, the development of production capacities, and the continuous enhancement of workforce skills. Since its establishment in 1993, TCO’s total procurement from domestic suppliers has reached USD 52.3 billion.
In 2025, TCO achieved a highlevel of Kazakhstani Content, reaching 71% due to increased volumes of goods procured from domestic manufacturers.
The company continues to expand opportunities for Kazakhstani enterprises. As part of its sustainability strategy, TCO plans further localization of production, the introduction of innovative technologies, and the ongoing development of Kazakhstani specialists. Particular emphasis is placed on building long-term partnerships that ensure stability and international competitiveness for local businesses.
TCO consistently supports the activities of the International Center for Development of Oil and Gas Machinery (IMBC). As part of this work, the company has signed a number of memoranda and agreements that are currently at various stages of implementation. Since 2024, TCO has conducted qualification assessments of 16 Kazakhstani manufacturers and included them in the company’s Approved Manufacturers List.
At the previous Kazakhstan Machinery Forum, TCO signed four contracts with three Kazakhstani companies for the supply of equipment totaling more than USD 10.5 million. In addition, during the Oil and Gas Machinery Forum held in Aktau, contracts worth USD 150 million were signed. These agreements are aimed at ensuring safe and reliable operations at the Tengiz field.
Participation in the XIII Kazakhstan Machinery Forum enabled TCO to exchange experience with industry partners, discuss current challenges and future prospects for the machinery sector, and underscore the importance of long-term partnerships among oil and gas operators, government institutions, and Kazakhstani manufacturers.
