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.
On April 23–24, 2026, AtyrauGeo‑2026 VI International Scientific and Practical Geological Conference, organized by the Kazakhstan Society of Petroleum Geologists (KSPG), was held in Atyrau. The event brought together around 250 specialists from more than six countries, as well as representatives of the Atyrau Oblast Akimat, the Ministry of Energy of the Republic of Kazakhstan, KazMunayGas National Company JSC, the KAZENERGY Association, relevant industry organizations, and the scientific community.
Tengizchevroil LLP (TCO) served as one of the key participants and a gold sponsor of the conference, supporting industry dialog and professional collaboration.
Vice-Minister of Energy of the Republic of Kazakhstan Yerlan Akbarov noted that “the oil and gas industry has entered a new phase, in which oil and gas professionals are faced with the challenge of exploring for and producing hydrocarbons at ultra‑deep horizons. This, in turn, requires the development and application of advanced technologies.”
The Tengiz field is known as one of the deepest and most technologically complex oil fields under development worldwide. As a result of the implementation of new technologies and the commissioning of the Third Generation Plant in 2025, TCO’s crude oil production reached 39 million tons.
As part of the conference, a book about Kazakh geologist and petroleum engineer Baltabek Kuandykov, the founder of KSPG, was also presented. TCO provided sponsorship support for the publication of the book, thereby supporting an initiative to preserve the professional heritage of the geological industry.
As noted by Alexey Vysotskiy, TCO Reservoir Management Manager:
“Baltabek Mukhanovich’s contribution to the development of Kazakhstan’s geological exploration industry and the advancement of the modern Tengiz field is of particular significance. We were sincerely pleased to support the preservation of his scientific and professional legacy, including through the publication of this book.”
During the conference, Baltabek Kuandykov’s contribution to the development of Kazakhstani professionals was also recognized. His work, knowledge, and professional principles played an important role in the development of local specialists, many of whom now hold key positions within the company. It should be noted that as of the end of 2025, 96% of TCO employees were Kazakhstani nationals.
