Figure 1: Position of transcontinental oil and gas belt in which 70-75% of total world oil reserves and more than 75% of world gas reserves are concentrated, in diagram of lithospheric plates. 1-oceanic rifts and transform faults; 2-boundaries of lithospheric plates in subduction and collision zones; 3-sedimentary basins with proven oil and gas presence: (figures in circles): 1-Timan-Barents Sea, 2-West Siberian, 3-Volga-Ural, 4-Caspian, 5-Western flank of Amu Darya, 6-South Caspian, 7-Persian Gulf, 8-East African (poorly studied); 4–primary regions with extensive unique oil (a) and gas (b) fields; 5–position of U ral riftogenic system; 6–fragments of East African Rift; 7–boundary of level of Earth gravitational potential (boundary of transition from decompressed abyssal masses of mantle to denser masses).
