Prospects for the exploration and development of large oil and gas deposits in megareservoirs in of the West Siberian oil and gas province

Abstract

Prospects of exploration and additional growth of gas and oil reserves in Cretaceous, Jurassic and Pre-Jurassic deposits in the northern part of the West Siberian oil and gas province, including the Arctic shelf of the Kara Sea, are considered. The economic feasibility of carrying out prospecting and exploration and development of oil and gas resources in Arctic conditions at large deposits associated with megareservoirs is substantiated. The conditions for the formation of large and giant hydrocarbon accumulations are considered. The issues related to their confinement to various types of traps and rocks of different lithological composition are discussed. The measures to achieve profitability and efficiency of exploration for oil and gas in difficult natural and climatic conditions of the Arctic are underpinned.
