Petroleum potential of the Riphean-Vendian Chunya sedimentary basin in the western Siberian Platform

The petroleum potential of the Riphean-Vendian Chunya sedimentary basin has been explored by seismic reflection profiling and drilling in recent years. The results of the study have been used to estimate the initial hydrocarbon resources in the basin and separately in four oil and gas areas distinguished in Riphean, Lower Vendian, and Vendian-Lower Cambrian reservoirs.
