Oil and Gas Bearing Complexes of the Sedimentary Cover of the Arctic Zone of the Siberian Platform Marginal Zones of the North of the Siberian Platform?

摘要

The report discusses issues related to the assessment of the resource base and the development potential of the Arctic zone of the Siberian platform along the Northern sea route, the region of Russia with a high concentration of oil and gas resources. The basic concepts on the geological structure and the oil and gas potential of the Arctic zone of the Siberian platform are based on seismic data tied to existing deep exploratory wells. To date, five petroliferous complexes have been described in the Yenissei-Khatanga (the Yenisei Bay, the Yenisei-Khatanga regional trough) Anabar-Khatanga (Anabar-Khatanga saddle, Khatanga bay) Anabar-Lena oil and gas regions (Anabar-Lena trough and adjacent shallow shelf of the Laptev Sea) and the South Laptev sea promising oil and gas region for the main oil and gas complexes: Riphean, Vendian, Vendian-Middle Paleozoic, Upper Paleozoic and Mesozoic. The report considers the results of the analysis of estimates of the filtration-capacitive properties of the sedimentary cover rocks in the marginal zones of the north of the Siberian platform available on 01/01/2019. Open fields are briefly described. The obtained results allow for the adjustment of state programs for the development of the Arctic zone of the Siberian Platform (Yenisei-Khatanga, Anabar-Khatanga and Anabar- Lena oil and gas regions, South-Laptev Sea promising oil and gas region). The interest of oil and gas companies to the Arctic region of the Earth has increased dramatically due to the intensification of work on the development of the Northern Sea Route (Fig. 1). The development of oil and gas fields in the Arctic zone along the Northern Sea Route is the key to economic stability and energy security of Russia (Action, 2016). In Russia, more than 300 offshore wells have been drilled, of which less than 90 are in the Arctic region. The Federal project for the development of the Northern sea route until 2024 is expected to invest 734.9 billion rubles. The project will be financed mainly by oil and gas companies and PJSC Rosatom, which are interested in transporting liquefied natural gas, gas condensate and oil along the Northern Sea Route to world markets. The Decree of the President of the Russian Federation dated 07.05.2018 № 204 "On national goals and strategic objectives of the development of the Russian Federation for the period up to 2024" aims to increase cargo traffic on the Northern sea route to 80 million tons by 2024. The total volume of hydrocarbon shipments will reach 48.8 million tons, which will make up 81.3% of the total cargo traffic. The volume of cargo to ensure the search, exploration and development of oil and gas fields along the Northern Sea Route until 2024 is estimated at several million tons.
