Analysis of distribution of oil and gas bearing basal terrigenous deposits in the territory of the Angaro-Lena stage of the south of the Siberian platform (by the example of the pravoborezhnogo location)

The distribution of Vendian-Cambrian basal terrigenous deposits, which are a search object for oil and gas on the territory of the Lena-Tunguska oil and gas province, is of practical interest, almost all identified accumulations of hydrocarbons are confined to them. A detailed study of the internal structure of the sedimentary strata formed in different lithofacies zones shows that the dominant sign of reservoir development for the territory is lithological homogeneity (heterogeneity).
