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.

SGI

Tengizchevroil produces liquefied petroleum gas (LPG), dry gas and sulfur in addition to crude oil.

Tengizchevroil (TCO) took part in Digital Almaty Forum, which brought together not only Government officials of the SCO and EAEU countries, representatives of Governmental agencies and ministries of the Republic of Kazakhstan, but also large taxpayers of the country, leading experts and entrepreneurs to exchange experience and ideas aimed at shaping a new era of the digital industry in Kazakhstan.

Tengizchevroil (TCO) took part in Digital Almaty Forum, which brought together not only Government officials of the SCO and EAEU countries, representatives of Governmental agencies and ministries of the Republic of Kazakhstan, but also large taxpayers of the country, leading experts and entrepreneurs to exchange experience and ideas aimed at shaping a new era of the digital industry in Kazakhstan.

- «Digital Almaty» is a unique platform where business representatives, international experts and the IT community get together. The ideas that have been developed in this forum find real solutions, - said Bagdat Mussin, the RoK Minister of Digital Development, Innovation and Aerospace Industry at the opening ceremony of the forum.

Throughout its 30-year history, TCO as an operator of Tengiz field which is technologically complex, has continued to actively introduce advanced technologies, contributing to development of digitalization in petroleum industry.

- At TCO, safety has always been and remains a top priority, and this principle applies, among other areas, to our approach to Digital transformation. In our program, we pay special attention to promoting safety culture focusing on solutions that improve safety of our employees and initiatives that help reduce the carbon footprint of the company, - Konilkosh Suyessinov, TCO Deputy General Director highlighted during his speech.

One of the innovations is launching of an electronic permit to work system (ePTW). This significantly reduced scope of paperwork and allowed the company to focus directly on the work, ensuring an understanding of safety requirements, availability and observance of protective

measures before the start of work. The electronic system has proven its effectiveness during the last turnaround. TCO Safely Completes 2023 Turnaround Ahead of Schedule (tengizchevroil.com)

- Being at our production sites, we are able to provide instant access to the available data via telephones or tablets. During the last turnaround of the Complex Technological Line-5 (KTL-5), we issued over 33,000 electronic work permits, which contributed to safe and timely completion of the scope, - noted Konilkosh Suyessinov.

The Digital Module of the Integrated Operations Control Center (IOCC) attracted special attention from the forum participants. The IOCC uses the latest digital technologies and is the only facility of its kind in oil and gas industry of Kazakhstan. It combines management of all TCO plants into a single operating model, thus creating conditions for operational data exchange between groups for faster and more effective decision-making.

- The IOCC digital module of TCO transition to an integrated production operation model, increasing efficiency and prompt of decision-making throughout the value chain. This digital module is equipped with functionality for integrated planning and performance control, allowing us to choose optimal production solutions, improve transparency and communication, thereby providing final value by increasing economic performance, - shared Konilkosh Suyessinov.

Digital transformation at TCO, is being developed with a constant focus on safe production, workforce and process safety and environmental protection. One of the first digital products implemented at TCO was Intelligent Vehicle Safety project. As part of it, every vehicle operated by the company and contractors has been equipped with a fatigue recognition system. The system sends signals in case of detected fatigue or drowsiness. This has helped to drastically reduce the number of incidents.

During the forum, Konilkosh Suyessinov noted that people are the main component of TCO’s digital transformation. Every year, TCO organizes a “Digital Yurt”, in which employees not only learn, but also develop skills and apply them during an internal Hackathon designed to solve real business problems. Various hackathons are also held among the workforce.
