Oil production

The Company possesses a well-balanced portfolio of assets located in the key Russian oil and gas provinces (West Siberia, Volga-Urals and Central Siberia). The АВ1С1+В2С2 reserves of oil and condensate under the Russian classification amount to 636 million tons. At yearend 2025, oil production amounted to 6.145 million tons. As of 31.12.2025, the operating well stock reached 1,900 wells, while the injection stock was 660 wells.

In 2025, a total of 117 new oil wells were commissioned with additional production of more than 880.6 thousand tons.

Well Interventions on declining well stock allowed for the production of additional 257.8 thousand tons. Interventions were carried out at 352 wells.

The Company's strategy includes investment activities aimed at maintaining production drilling volumes, bringing new reserves into development in promising areas, and creating new and upgrading existing infrastructure.

The main goals of the RussNeft production complex within the framework of the approved development strategy are increasing the resource base and ensuring stable level of hydrocarbon production.

To achieve these goals, a number of effective production programs have been developed that allow for the formation of optimal development and production management system and the reduction of operating costs.

Key programs and activities:

• Implementation of additional appraisal of deposits and exploration program

• Implementation of engineering and technological solutions for the effective development of low-margin deposits and hard-to-recover reserves (HTR)

• Introduction of innovative methods for intensifying oil production from HTR and increase in oil recovery

• Improving the operation efficiency of mature fields

• Implementation of measures to raise the technological support for oil production process

• Monitoring of field development using permanent geological and hydrodynamic models.
