The article is prepared based on the results of the work carried out within the framework of the Program of the State Academies of Sciences for 2013-2020. Section 9 "Earth Sciences"; directions of fundamental research: 131. "Geology of hydrocarbon fields, fundamental problems of geology and geochemistry of oil and gas, scientific foundations for the formation of a raw materials base for traditional and non-traditional sources of hydrocarbon raw materials" and 132. "Integrated development and conservation of the Earth's interior, innovative development of mineral fields and deep processing of mineral raw materials ", within the framework of the projects "The Fundamental Basis of Innovative Technologies in the Oil and Gas Industry ", No. AAAA A16-116031750016-

The interest of oil and gas companies in the Arctic region of the Earth, despite the difficulties in the geological exploration, the development and the exploitation of discovered fields, in access to markets for the produced hydrocarbons is quite high. According to the US Geological survey, the subsoil of the Arctic zones of five coastal States – the United States, Canada, Russia, Denmark and Norway – contains at least 525 billion BBOE (barrels of oil equivalent) or 75 billion tons, including the subsoil of the Arctic zone of Russia – 315.4 billion BBOE (26). The Arctic zone of the Eastern Siberia is characterized by a harsh climate (in winter the temperature drops below −60 °C on land and to −40 °C at sea), the presence of the permafrost, the lack or remoteness of the infrastructure for the delivery of the necessary equipment and materials, the transportation of produced hydrocarbons, short periods of the field work from November to April on land, from July to September at sea (6, 7, 25). The basic concepts of the geological and tectonic structure and the oil and gas content of the land and the adjacent shelf of the Arctic zone of the Siberian platform are based on the seismic data, tied to the existing deep parametric and exploratory wells. To date, five regional seismostratigraphic complexes have been identified and described: the Mesozoic-Cenozoic, the Permian-Lower Triassic, the Upper-Middle Paleozoic, the Upper Proterozoic-Cambrian and the surface of the basement. The evaluation of the potential hydrocarbon resources was carried out in the Yenisei-Khatanga, the Anabaro-Khatanga, the Anabar-Lena and part on the Laptev Sea oil and gas regions.

The paper was prepared for presentation at SPE Russian Petroleum Technology Conference, 15-17 October, Moscow, Russia.
