Geological exploration

Highlights of strategically important events include the Company obtaining a license for the geological study of the potentially productive hard-to-recover oil-saturated strata in the southern part of the Priobskoye field, obtaining a license for study, exploration and production at the North Vrangelevsky (offshore), Stakhanovsky and Otdelny areas and acquiring several license areas in the Orenburg Region, where Gazprom Neft is setting up a new production cluster. In addition, the Company obtained the right to use subsoil resources at two license areas — Severo-Zapadny and Kheysovsky — located on the shelf of the Pechora and Barents Seas.
