Northern part of the North Tungussky Petroleum Area is still one of the extremely underexplored oil and gas promising territories in the Lena-Tungussky Petroleum Province. Never a one stratigraphic well has been drilled within the Putorana Plateau area that exceeds 290 000 km2; therefore, the key geological, geochemical parameters of sedimentary cover deposits, without which the appropriate assessment of its oil and gas potential is impossible, are not determined. Nevertheless, given the current understanding of the hydrocarbon resource potential of the North Tungussky Petroleum Area, which are based on a quantitative assessment carried out by Russian institutes in 2017, integrated studies of this oil and gas bearing area using modern geological and geophysical methods is a top priority task within the framework of oil and gas occurrence prediction in the regional stage. Focus areas, methods, and scope of geological exploration recommended in this paper will make it possible to solve the main tasks in full.
