Some aspects of the placement of hydrocarbon accumulations within the Terek-Caspian trough

The article is devoted to the distribution of oil and gas accumulations within the Terek-Caspian trough. Various factors that determine the spatial distribution and formation of hydrocarbon deposits in the studied region (tectonically, stratigraphically) are considered. The distribution of total oil reserves by large stratigraphic complexes is given in tabular form. Information is given on hydrocarbon deposits depending on their confinement to certain structural forms and the phase state of the fluids. The prospects of opening new accumulations of oil and gas with a further increase in geological exploration for oil and gas are determined.
