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.

Working safely is a TCO core value and everyone’s responsibility

In 2021, TCO employees and contractors worked over 123 million man-hours with 10 Days Away from Work incidents. While this is solid performance, TCO strives for zero workplace injuries and is continuously working to improve in this area. Living this commitment will ensure success in fatality prevention and process safety, the two cornerstones to incident-free construction and operations.

Occupational Health and Safety Management Process

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.

02

Process Scope

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.

03

Working with TCO as a Business Partner

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.

04

Protection of people

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.

How artificial intelligence is used in Tengizchevroil

Apr 6, 2024, 09:59 AM by Nurtay Nudiyev
Tengizchevroil LLP (TCO) continues to introduce new artificial intelligence tools that can effectively help address requests from company specialists. TCO experts spoke about this and how digitalization has become an important vector in the company’s development, during the 21st North Caspian Regional Exhibition “Atyrau Oil and Gas,” where the company is the main sponsor.

Tengizchevroil LLP (TCO) continues to introduce new artificial intelligence tools that can effectively help address requests from company specialists. TCO experts spoke about this and how digitalization has become an important vector in the company’s development, during the 21st North Caspian Regional Exhibition “Atyrau Oil and Gas,” where the company is the main sponsor.

At TCO, the creation of a digital culture began with training of all personnel in the necessary computer skills and knowledge. Digital transformation, like any other initiative at TCO, is being developed with a constant focus on safe production, employee safety, process safety and environmental protection. TCO places the highest priority on initiatives and digital products that improve the safety of people and production.TCO pays special attention to the safety of its people and production process safety.

During the panel session, TCO Digital Champion Marat Kuatov told participants and guests of the exhibition that the implementation of AI is a powerful tool that can transform not only operational processes, but also the outlook for the future.

- The use of AI allows us to leverage production, improve safety, as well as predict and adapt to changes in the industry. The introduction of AI is not just a technological step, it is a strategic decision that helps companies remain competitive and sustainable from a long term perspective, says Marat Kuatov.

Until 2020, the company focused on development of Digital Foundations. The field, wells, oil gathering system, plants, export facilities were digitalized, and complex IT systems were introduced. The development of cloud systems and the creation of an extensive database and platform were ongoing. Even during the coronavirus pandemic, TCO actively used digital platforms to ensure the safety of employees and coordinate work.

In 2020, the company implemented production process management systems, smart transport safety technologies, and pilot programs for drones and augmented reality glasses at the Future Growth Project - Wellhead Pressure Management Project.

In 2023, a “Digital Twin of the KTL plant” program was successfully completed at the Tengiz field. The virtual plant twin allows TCO experts to create scenarios for various situations, as well as test and optimize processes. Process optimization with the help of a virtual twin allows you to use resources more efficiently and reduce waste and impacts on the environment. Thus, the implementation of the virtual twin was not just an isolated example, but a step into the future, where digital solutions become key to the efficiency and sustainability of the operations.

Digitalization has positively impacted water resource management at the Tengiz field. The successful implementation of the water meter reading system has significantly improved the efficiency of the water resources department of Tengiz Facilities Management. The system allows to remotely collect data from water meters, eliminating the need for manual readings and increasing operational safety.

One of the company’s innovations is the transition to an electronic work permit system (ePTW). It significantly reduced the amount of paperwork and allowed the company to focus directly on work and safety measures. For example, during 2023 turnaround at the 5th process Line of KTL, more than 33 thousand electronic work permits were issued that contributed to the safe and timely completion of the works. The ability to obtain electronic signatures on documents has speeded up processes that previously took a long time. This technological shift not only upgraded TCO’s operation, but also significantly increased its efficiency and responsiveness.

At Tengiz field, the processing of large data allows to identify patterns and optimize processes, as machine learning algorithms are used to predict and adapt to changes in the industry.

— The safety of our people and production safety are our top priorities at TCO. And we use artificial intelligence for this purpose. Thanks to AI, we are making our work environment safer and more efficient. And we have more than 20 such AIs,” Marat Kuatov emphasized.

Kuatov also said that TCO is currently developing new AI tools that can respond to engineers’ requests. For this purpose, a repository of more than 300 technical specification documents is used to effectively assist in addressing requests from the company’s specialists.
