The article proves the new concept of formation of hydrocarbons (HС) and their reservoirs in the Caspian megabasin. The South-Caspian depression, being the most hog part of the Caspian basin, is the powerful center of HC generation, which along with the large geostructural elements, such as Middle, Northern Caspian, Tersko-Caspian front deflection and others has been playing a clue role in the formation of oil and gas, and hydrocarbon reservoirs in the Caspian megabasin. On the basis of determination of the degree of participation of the deep mantle breaks in generation of hydrocarbons, with the account of petrophysical characteristics and the residence period of sedimentary complex in the stage of katagenesis, proved has been the possibility of formation of oil and gas, their migration within the Tersko-Caspian depression and formation of trans-boundary zones of oil-gas accumulation.
