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.

The results of the Community Investment Program in Tengizchevroil

Dec 22, 2023, 07:04 AM by Nurtay Nudiyev
An open final event was held in Atyrau, where the Partners of Tengizchevroil Community Investment Program (CIP), non-governmental organizations, spoke about the results of their work during 2023. It is worth noting that in 2023, the CIP budget was increased, which made it possible to implement 21 projects for a total amount of 2.5 million US dollars.

An open final event was held in Atyrau, where the Partners of Tengizchevroil Community Investment Program (CIP), non-governmental organizations, spoke about the results of their work during 2023. It is worth noting that in 2023, the CIP budget was increased, which made it possible to implement 21 projects for a total amount of 2.5 million US dollars.

“This year Tengizchevroil celebrated its 30th anniversary, and many social projects were implemented. Undoubtedly, each of them contributes to the development of Atyrau Oblast. I would like to note that in the future we are ready to support the implementation of such social projects,” said Deputy Akim of Atyrau city Nurzhan Yermukhanov.

Within the Program, NGOs propose their projects on their own and TCO only gives financial support. This year, social projects covered such areas as healthcare, education, environmental protection, the formation and development of civil society and preservation of Kazakh culture and historic heritage. The Kazakhstan Association of Family Physicians (KAFP) continued its work to improve the qualifications of medical personnel. One of the remarks of this year was a trip to Taraz, Zhambyl Oblast for sharing experience.

This year, “Biz de Adambyz” Public Foundation implemented 2 projects, one of which proposed an innovative solution to the problems of accessibility of social facilities in the city. Volunteers and residents of the project compiled and launched an electronic map of the accessibility of social facilities for low-mobility groups of the population, which includes not only people with disabilities, but also elderly people, pregnant women and mothers with children under 7 years old. During the monitoring, violations in space planning for people with disabilities were also identified. Many entrepreneurs took into account the recommendations and made changes to the appearance of small and medium-sized businesses, which was undoubtedly noted as one of the positive results of the project.

In his welcoming speech, Tengizchevroil General Manager for Policy, Government and Public Affairs, Darmen Aronov, also noted the growth of local NGOs. “This year, 16 NGO partners are implementing 21 projects in Atyrau region and Zhylyoi district in particular. In addition, their projects have directly impacted 11,000 people this year! Credits go to our partners, and we are happy to share the results of their work. TCO, as a socially responsible company, will continue its effort in the social sphere,” he said.

The Community Investment Program was launched in 2010. During this period, 129 social projects were implemented. More information about each of the projects can be found by the link CIP TownHall (tengizchevroil.com).

However, in addition to CIP, TCO also implements other projects in the field of social investment. Thus, within the framework of the voluntary social and infrastructure program “Egilik”, in this year only an additional school building for 350 seats was opened in Tushchykudyk village of Issatay

district, and a school named after Magzhan Zhumabaev No. 1 was opened in Atyrau city. On the New Year eve, the grand opening of the central regional hospital with 75 beds was held in Kulsary.

In addition, as part of the sponsorship provided to Atyrau Oblast, including Kulsary city, TCO donated 3 taxis for people with disabilities, 6 ambulances to Zhylyoi district and 4 special vehicles for uninterrupted operation of housing and public utilities, as well as equipment for therapeutic exercise classes at the Center for Special social services No. 3 and the Nursing home. A technology room for visually impaired students of boarding school No. 3 were fully equipped and much more. In addition, the second year in a row, TCO funds the treatment of 100 pensioners in our Oblast at the Atyrau sanatorium.
