Complex Technology Line – KTL

Tengizchevroil inherited an oil and gas separation plant when it took over operations at Tengiz in 1993. This first generation of the Tengiz plant is called the KTLs (Russian for Complex Technology Lines). TCO has invested in expanding and improving the KTLs over the life of the operation. Today, the KTLs consist of five oil and gas processing trains and are now significantly more efficient and environmentally friendly. Started up in 1991, KTL-1 consists of two trains and has the capacity of around 7,000 tons per day per train. KTL-2, which also has two trains with the same capacity was successfully completed and started up in 1996. Last KTL train 5 was put on production in 2001 along with first oil from Korolev field. The capacity of train 5 is around 11-12,000 tons, per day.

Second Generation Plant – SGP

TCO's production capacity has risen with the commissioning of the Second-Generation Expansion Project in 2008, which includes the Second Generation Plant (SGP) and Sour Gas Injection (SGI) facilities. This expansion allowed TCO not only to double oil production in Tengiz, but also to improve the environmental performance and increase production efficiency. TCO completed the expansion in the third quarter of 2008, which brought daily capacity to 75,000 metric tons (600,000 barrels) of crude oil and 22 million cubic meters (750 million standard cubic feet) of gas. SGP stabilizes and sweetens crude oil, as well as separates and processes natural gas into gas products and elemental sulfur. SGP is the largest single sour crude processing train in the world.

TCO encouraged contractors to promote personnel nationalization

The “Roadmap on subsequent replacement of foreign employees through routine training of Kazakhstani specialists” was presented to contractors and subcontractors implementing their activities at Tengiz field. The working meeting was attended by representatives of Employment Coordination and Social Programs department of Atyrau Oblast, TCO and more than 100 private contracting companies.

The “Roadmap on subsequent replacement of foreign employees through routine training of Kazakhstani specialists” was presented to contractors and subcontractors implementing their activities at Tengiz field. The working meeting was attended by representatives of Employment Coordination and Social Programs department of Atyrau Oblast, TCO and more than 100 private contracting companies.

Azamat Mambetov, Head of Employment Coordination and Social Programs Department noted that: “During the meeting with representatives of major businesses in 2022, the RoK President mentioned about the necessity to invite foreign experts, where there is a shortage in organizations. In this direction, a Roadmap has been developed in the regions by the RoK Ministry of Labor and Social Protection, providing for measures for planned training of Kazakhstani personnel for subsequent replacement of foreign colleagues. In general, the number of expat employees decreased by 3.6 times compared to 2019”.

The implementation of the “Roadmap” is planned for two years. Its main focus is the training and re-qualification of citizens in relevant specialities for further replacement of foreign labour, holding job fairs, creation of new jobs for persons with disabilities, as well as organization of mentoring for Kazakhstani workers by foreign specialists. The role of short-term training and retraining courses for labor professions being implemented by TCO, was emphasized. According to Mr. Mambetov, 80% of those who completed training in the period from 2019 to 2023 were employed.

Tengizchevroil continues to support the state policy of developing potential of Kazakhstani personnel and recommends its business partners follow the example. More than 95 percent of TCO employees are now Kazakhstani nationals. As a result of the various programs, more and more Kazakhstani citizens are taking up leadership positions. Thus, the share of Kazakhstani nationals among top and middle managers in TCO’s base business is close to 88 percent. Overall, since 2007, more than 460 national employees have replaced foreign colleagues in key leadership and technical positions,” said TCO Deputy General Director, Konilkosh Suyessinov.  

People are the main asset of the company. The safety and well-being of employees, and the development of high potential, are at the core of TCO’s human resources strategy. To date, TCO has invested over $100 million to develop and expand the knowledge and skills of local employees. To attract and retain talented professionals, TCO offers significant benefits and social packages, implements talent management and well-being strategies, and promotes an organizational culture that supports diversity and inclusion, and fosters an environment of integrity trust, and teamwork.

Also, TCO provides promising Kazakhstani employees with opportunity to gain domestic and international experience working for TCO shareholders and helps them develop unique qualifications, knowledge of international standards, technologies and best practices so that they can go on to senior management and technical positions. Since 1999, more than 470 TCO national employees have been assigned temporarily to work in TCO's international and Kazakhstani representative offices.

Skilled specialists not only successfully occupy key positions in the company, but also bring their knowledge and experience to other sectors of the economy, which in turn stimulates the creation of new jobs, improving labour productivity and increasing the country's competitiveness in the international arena.
