N2 - The work is devoted to the analysis of the geological structure and assessment of the oil and gas potential of the Anabar–Khatanga and Lena–Anabar oil and gas areas (OGA) of the Lena–Tunguska oil and gas province, which are located on the continental margin of the Siberian Platform, on the coast of the Laptev Sea. Administratively, the study area includes the northeastern regions of the Krasnoyarsk Territory, the northwest of the Republic of Sakha (Yakutia), the offshore of the Khatanga Bay and the southern, transit part of the Laptev Sea (Khatanga–Lena interfluve). Based on integrated interpretation of geological and geophysical materials, we present regional-zonal models of the geology of the upper Proterozoic–Phanerozoic deposits of the Arctic regions of the Siberian Platform, sets of seismogeological sections, structural and parametric maps, results of structural-tectonic analysis, potential estimates of oil-producing formations; analysis of reservoir properties and types of oil and gas promising objects, and a quantitative assessment of hydrocarbon resources. The study area is of interest in terms of oil and gas potential. In this region, the Central Olgin field was discovered, numerous bitumen, oil and gas shows were noted. A series of oil-producing formations enriched in organic matter occurs in the sedimentary cover, and in the sections of all sedimentary complexes, high-capacity reservoirs are distinguished. There are prerequisites for the formation of both anticlinal and complex oil and gas promising objects. The prospects for the oil and gas potential of the Anabar–Khatanga OGA are mainly associated with Permian terrigenous deposits and Cambrian–Devonian carbonates. In the Lena–Anabar OGA, all upper Proterozoic–Paleozoic sedimentary complexes from the Riphean to the Permian level are of interest in terms of oil and gas potential.
