PRE-CONDITIONS OF OIL AND GAS POTENTIAL OF EXPANDED LEGAL SHELF OF THE RUSSIAN FEDERATION IN THE ARCTIC OCEAN

Pre-conditions of oil and gas potential of the “expanded” shelf area under application of Russia to the UN Commission on the Borders of the Continental Shelf are fi rst considered. The features of geological and geophysical knowledge of the area are analyzed. Geohistorical background of oil and gas potential and change law of “basin” cover thickness are briefl y considered. Existence of transregional shelf-slope Chukchi-East Siberian megatrough of polycyclic development, which is the main objective for forecasting and prospecting, is substantiated for the fi rst time in the literature; data of preliminary quantitative assessment of resources by comparison with the standard and on the basis of basin modeling are given. The directions for further research are outlined.
