KazMunayGas CEO Askhat Khassenov has instructed the company to continue implementing technological and digital solutions, with a focus on its production efficiency and further scaling. This was announced by the press service of KazMunayGas (KMG), following CEO Khassenov’s visit to the production facilities of Ozenmunaigas (OMG), where new technologies are being introduced, and a meeting was held on their further application to enhance the development of the Uzen and Karamandybas fields. "Hydraulic fracturing remains a key technology for increasing oil production.
It is carried out annually at around 400 wells, generating more than 500,000 tons of oil per year. The company continues to improve the technology in line with global best practices. In 2025, Ozenmunaigas successfully conducted foam-nitrogen hydraulic fracturing and hydraulic fracturing using synthetic fluids, with their commercial-scale rollout beginning this year," the KMG said.
For mature fields such as Uzen and Karamandybas, a key priority is to slow the decline in production and reduce water cut. To this end, OMG is implementing a range of polymer-based technologies. In particular, the company has optimized the water-alternating profile modification technology using polymer injection.
Treatment parameters are selected individually for each well based on reservoir properties and the characteristics of the chemical agents used. This approach has helped reduce the cost of operations by half, while the annual production effect from the technology amounts to around 200,000 tons of oil. Pilot industrial testing of polymer flooding is also underway to increase oil recovery and reduce water cut.
Successful results will allow the technology to be scaled up in areas with highly depleted reserves. Horizontal drilling is another promising area. The technology increases the contact area between the well and the reservoir and allows additional reserves to be brought into production.
Four wells have been selected for the project. Work is also continuing on sidetracking, which enables inactive wells to be returned to operation. More than 15 wells have been selected for this work.
