Gas Projects
In June 2017, the Company launched an Associated Petroleum Gas (APG) Treatment Unit with an annual capacity of 150 million $m^3$. This facility was designed specifically to utilize associated gas from the Prorva group of fields located in the Zhylyoi district of the Atyrau region. At present, the sales-grade gas produced by this unit is supplied directly into the "Central Asia – Center" main pipeline, an achievement that has significantly reduced the necessity of flaring associated gas across the Prorva fields.
The integrated gas treatment process employs LO-CAT sulfur recovery technology provided by Merichem. This specific technology is recognized for being environmentally safe while ensuring a high efficiency rate in converting hydrogen sulfide into harmless, elemental commercial sulfur intended for sale on both domestic and international markets. To ensure safety and precision, the entire gas treatment cycle is fully automated and incorporates multiple levels of emergency protection systems.
Similar APG treatment facilities have been operating successfully since the 2013–2014 period at the Company's Vostochny Makat and S. Balgimbayev fields. These units, with annual capacities of 40 million $m^3$ and 20 million $m^3$ respectively, play a vital social role by providing sales gas at discounted rates to the populations of the Isatay, Makat, and Kyzylkoga districts within the Atyrau region.
With a focus on increasing operational efficiency and economic profitability, the Company is currently executing pilot projects for the processing of APG into electrical energy. These initiatives are taking place at the Uaz Severny field (Kainarmunaigas OGPU) as well as the Yugo-Zapadnoye Kamyshitovoye and Gran fields (Zhaikmunaigas OGPU). The strategy involves utilizing associated gas to fuel gas-piston and gas-turbine power plants, with the resulting electricity used to meet the Company's own internal needs. Successful implementation will support additional oil production while increasing the reliability of independent power supplies for both social and production-related facilities.
Starting in 2025, as part of a broader gas commercialization strategy, the Company completed the construction of an integrated APG treatment unit at the Yugo-Vostochnoye Novobogatinskoye field. This facility produces sales-grade gas, a stable gas condensate (pentane-hexane fraction), and a technical propane-butane mixture (LPG). This project was realized with the participation of a private investor, allowing the resulting sales gas to be delivered into the "Makat-North Caucasus" main pipeline system at incentive prices established by the Ministry of Energy of the Republic of Kazakhstan.
Also in 2025, the Society began the first stage of a project to develop the gas deposits of the Zapadnaya Prorva field. This phase targets a volume of up to 100 million $m^3$ per year through an accelerated industrial development schedule. Supported by attracted investments, the project focuses on refining raw natural gas to commercial standards for sale into the "Central Asia – Center" pipeline at the government-mandated incentive price.
Simultaneously, a project was launched at the S. Nurjanov "Vostochnoye Pole" field to utilize up to 70 million $m^3$ of associated gas annually. This plan involves the installation of booster compressor stations to maintain the necessary technical parameters for sweet (non-sour) gas. This gas is then dehydrated at the first phase unit before being sold into the "Central Asia – Center" pipeline system.
Continuing this momentum and following the Ministry of Energy’s program to expand Kazakhstan’s gas resource base, the Company has moved toward a full-scale development project for the Zapadnaya Prorva gas deposits. This ambitious expansion targets a volume of up to 860 million $m^3$ per year. At the current stage, a comprehensive feasibility study has been completed by the AtPF design institute of KMG Engineering LLP.
