Gas production

At the yearend 2024, the actual gas production of RussNeft amounted to 2.004 bn m³, including 277 mln m³ of natural gas. The Company's fields yielded 1.727 bn m³ of APG. Meanwhile, the level of gas utilization at the yearend was maintained at 97.05 %, thus having met the state's requirement aimed at maximally reducing the negative impact of production on the environment.

Program of efficient use of associated petroleum gas (APG)

Currently, the Company's task is to maintain the rate of effective APG utilization, improve the energy efficiency of oil production, and reduce greenhouse gas emissions. This activity will be pursued in the framework of the corporate program developed for 2024-2027. In accordance with it, a number of major engineering and gas infrastructure facilities is planned to be financed.

Gas business

The gas business development is one of the priorities for the Company. In 2022, a decision was made to implement a project for technical upgrading of the Stepnovsky oil treatment area in the Saratov region as one of the components of the conducted large-scale upgrade of the gas compressor unit with a capacity of more than 50 mln m³/year. Completion of the project is scheduled for 2025.

In 2024, measures were taken to meet the requirements of the technical regulations of the Eurasian Economic Union "On the safety of combustible natural gas prepared for transportation and (or) use".

Oil and gas exploration and reserves

The total number of oilfields is 122 (State Register of Reserves of the Russian Federation as of 01.01.2025).

The Company's enterprises are divided according to territorial and operational criteria into the following groups:

• West Siberian
• Volga Region
• Central Siberian

The oil and gas content of the fields within the boundaries of the Volga group is associated with terrigenous and carbonate rocks of the Middle-Lower Carboniferous and Devonian, while in the West Siberian and Central Siberian regions with deposits of the Upper Jurassic and Neocomian.

The prospects for the discovery of new oil and gas deposits, as well as the expansion of the oil-bearing capacity of previously discovered fields, are related to the strategy for stable implementation of the exploration program with a focus on the detailed high-quality CDP (common depth point)-2D/3D seismic surveys and to the strategy of successful prospecting, appraisal and exploration drilling.

It is worth noting, that lately the hard-to-recover and unconventional reserves have become the main sources of replenishment of the reserves portfolio for the medium term. The growth of competencies in research and industrial development of HTR, the analysis of ongoing retrospective exploration work and generalization of its results allow us to promptly rank projects in the Company, identifying the most promising areas of development (eg: Verkhne-Shapshinskoye, Tagrinskoye, Vostochno-Kamennoye, Zapadno-Varioganskoye fields).

Since 2017, the Company has continued active industrial development of deposits of the Achimov sequence based on the results of a comprehensive methodological approach to the study of productive sediments of the Verkhne-Shapshinskoye field. In total, since 2017, reserves evolution for the Achimov deposits of the Verkhne-Shapshinskoye field have amounted to more than 44 million tons of oil.

The implementation of the production drilling program in 2024 at the Tagrinskiy license area confirmed the high effectiveness of the ongoing exploration work and enables real time updating for the geological model of the Achimov deposits. Since 2015, the total changes in the oil reserves of the Achimov sequence of the Tagrinskoye field amounted to more than 55 million tons, while the reserves of the HTR category added more than 75 million tons.

Following the implementation of the exploration and production drilling program in 2024, the change in liquid hydrocarbon reserves amounted to more than 10 million tons. The bulk change in reserves in 2024 is the increase in oil reserves at the Tagrinskoye field, amounted to 4.3 million tons of oil. Also, a significant increase in reserves occurred at the Zapadno-Varyeganskoye field, which amounted to 1.1 million tons of oil. As a result of the increase in the area of ​​​​the Belokamenny and Bayirsky license areas, reserves increased by 1.9 million tons of oil.

In the 2023-2024 field season, the Company, in the territory of the Khanty-Mansiysk Autonomous Okrug - Yugra, carried out seismic exploration work CDP-3D in the amount of 160 km² at the Vodorazdelny license area, as well as office seismic exploration work CDP-3D in the amount of 810 km² at the Tagrinsky license area. In 2024, field seismic surveys of the CDP-3D type were launched in the volume of 245 km² at the Tagrinskoye license area, which will be the basis for further creation of a unified seismic-geological model of the Tagrinskoye field, thus determining the development vectors of the site, improving the quality and efficiency of production drilling.

In order to annually replenish the mineral resource base, the Company plans to maintain the exploration policy based on:

• search and exploration of new hydrocarbon deposits in oil and gas-bearing horizons due to prospecting, appraisal and exploratory drilling, as well as advanced production drilling;
• improving the efficiency of prospecting, appraisal and exploratory drilling by improving the quality of CDP - 2D/3D seismic surveys, enabling detailed study of complex hydrocarbon traps, including in deep-lying complexes represented by hard-to-recover reserves and unconventional reservoirs;
• expanding the boundaries of the oil and gas potential of already identified deposits;
• acquisition of potentially promising new subsoil areas based on geological, as well as technical and economic assessments.
