The paper discusses the main causes of inclined oil-water contacts occurrence in the deposits Strezhevskoye and Krapivinskoe of the West Siberian plate, confined to the deposits of Vasyugan formation. The authors believe that the main reasons for the inclined oil-water contacts occurrence are the heterogeneity of the reservoir rocks lithofacies characteristics, regional hydrodynamic pressure of reservoir waters and the imposed catagenesis during the oil deposits formation. For this purpose, the facial analysis of the productive deposits was conducted and the data on reservoir permeability were used.
