Annotation:

The article considers some specific features of the composition and oil bearing capacity of low-permeable reservoirs of the Tyumen Formation and Pre-Jurassic deposits of Nazymskiy group of fields. The results of the resource potential revision of hard-to-recover reserves are illustrated by the examples of Aprelskiy and Srende-Nazymskiy subsoil areas, thus paying a direct impact on the optimization of the exploration strategy. Confirmation of the oil-bearing capacity of the Pre-Jurassic complex and involvement of additional oil reserves into the development allow more efficient use of the hydrocarbon resource base and current production infrastructure. The prospects for the reserves increase of the Pre-Jurassic complex in the Western Siberia, which may become a source of supporting oil production in the region are dependent on the development of the technologies providing for hydrocarbon deposits localization and prospecting as well as improvement of economic stimulation measures of the deposits exploration and development. It is noted that "NK "Yugranefteprom" LLC pays much attention to geological exploration as a source of replenishing hydrocarbons raw base in Khanty-Mansi Autonomous Territory–Yugra.
