Abstract

Geological and geophysical researches and exploration works conducted in the Russian Arctic offshore during the last two decades indicate the presence of extensive sedimentary basins. The data coverage in this vast continental margin is uneven, and the reliability of hydrocarbon prediction varies significantly from one basin to the next. Nevertheless, the existence of a major frontier Barents-Northern Kara Oil and Gas Province (BNKP) is quite evident. The BNKP encompasses the Barents Sea and the Northern Kara Sea subbottom, the islands along the shelf edge, the Kola Peninsula shelf, the Arkhangelsk coastal territory, and a large part of the northernmost Komi Republic. The total area of BNKP is close to 1,500,000 sq. km, and the sediments in the deepest depocenter (South Barents Basin) reach 16--18 km. Vast areal extent, great thickness of sedimentary cover, favorable conditions for oil and gas generation and accumulation, presence of oil and gas fields in all major sequences suggest a very high hydrocarbon potential for the BNKP.
