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.

Sour Gas Injection – SGI

SGI re-injects one third of produced sour gas back into the Tengiz reservoir at very high pressures to maintain reservoir pressure. The injection compressor is like no other compressor in the world and represents the state of the art in sour gas injection technology. SGI enables about 25% of total TCO oil production as well as pressure maintenance to reservoir.

Tengizchevroil aims to expand its cooperation with local producers in Kazakhstan

Feb 14, 2025, 12:56 PM by Nurtay Nudiyev
At the meeting of the Committee on Ecology and Natural Resources of the Majilis of the Parliament of the Republic of Kazakhstan, held on February 13, the management of Tengizchevroil (TCO) presented a report on the procurement of domestic goods in 2024 and shared their plans for 2025.

At the meeting of the Committee on Ecology and Natural Resources of the Majilis of the Parliament of the Republic of Kazakhstan, held on February 13, the management of Tengizchevroil (TCO) presented a report on the procurement of domestic goods in 2024 and shared their plans for 2025.

Kevin Lyon, General Director of the company, said that the sum of purchases of goods, works and services for the last year amounted to about 3 billion US dollars. At the same time, TCO's cooperation covered not only Atyrau Oblast, but also other regions of the country. He emphasized that the company actively works with local manufacturers and seeks to maximize the involvement of Kazakh enterprises in the supply chain.

“In July 2024, TCO entered nine memorandums of understanding with Kazakhstani manufacturers, including Sigma Solutions, Honeywell Automation Controls System, and FAD Kazakhstan. These companies have already been successfully qualified, and six more are currently undergoing technical evaluation. Special attention is being paid to the development of local production of overhaul equipment,” said the TCO General Director.

The company also announced plans to increase the share of Kazakhstani content in its purchases. In 2024, this figure reached 69%, and over the next decade, it is expected to grow to 75%.

In his presentation, Kevin Lyon also shared data on nationalization. Currently, about 96% of TCO employees are Kazakhstani nationals. Additionally, hundreds of Kazakhstani employees have taken key and critical technical and management positions, replacing foreign specialists. The company continues to focus on nationalization processes and plans to increase this figure to 98% in the coming years.

TCO’s financial contribution to the country’s economy remains significant. We note that the company paid more than $11 billion in taxes in calendar year 2024 alone, and total payments to Kazakhstan since TCO was founded in 1993 have exceeded $201 billion.

In addition, Kevin Lyon reminded that last month TCO successfully launched oil production at the Third Generation Plant (3GP) in the Tengiz field. The company plans to ramp up production in the coming months, and once the facility reaches full capacity, it will increase TCO’s annual production by 12 million tons of oil. This will provide significant additional revenue for Kazakhstan through direct financial payments to the republican budget.
