This study presents the results of recent regional seismic exploration and deep drilling efforts in the Sayan-Yenisei syneclise and adjacent areas of the Lena-Tunguska petroleum province. These results were used to build a series of structure maps for Riphean, Vendian and Lower Cambrian reflectors; thickness maps of the Riphean and Vendian terrigenous geoseismic sequences within the syneclise, and a tectonic map of the Vendian-Paleozoic structural stage of the Sayan-Yenisei syneclise. The proposed oil and gas geological zoning of the Sayan-Yenisei potential petroleum area enabled us to identify eight potential petroleum regions and perform a quantitative assessment of the hydrocarbon potential. The original in-place resources of the Sayan-Yenisei potential petroleum area are estimated to be 3 billion 231 million tons of hydrocarbon equivalent, including 3 trillion 39 billion m³ of gas and 192.7 million tons of condensate. It is shown that over next 15-20 years, up to 1 trillion m³ gas reserves can be explored in the Sayan-Yenisei potential petroleum area. it is proposed to consider the Boguchany village as a large gas conversion and helium production center.
