Oil and gas bearing collectors of deep-lying Lower Carboniferous complexes of the central part of the Dnieper-Donets Basin
Deep-seated (at the depths more than 5 km) sedimentary complexes of the most deep depressions of the World (in Ukraine - the central part of the Dnieper-Donets Depression, the Donets Basin, the Black Sea, the Pre-Carpathian foredeep - Carpathians - Trans-Carpathians) which will possibly be the main...

Deep-seated (at the depths more than 5 km) sedimentary complexes of the most deep depressions of the World (in Ukraine - the central part of the Dnieper-Donets Depression, the Donets Basin, the Black Sea, the Pre-Carpathian foredeep - Carpathians - Trans-Carpathians) which will possibly be the main hydrocarbons sources in the future. So, the studies of regularities of oil-and-gas presence in deep-seated complexes acquires a special strategic significance. Advantageous progression of this line of oil and gas exploration requires the resolution of the complex of problems. Among them the problem of reservoirs prediction is the most complicated. Its solving is possible only on the base of reliable concept of the nature of deep-seated reservoirs.
