Annotation:

The article presents the results of the studies of the rock samples geochemical parameters from the wells drilled within the northern side of the Caspian depression and the zone of its juncture with the southern part of the Buzuluk depression. Potential oil and gas source strata were identified and characterized within the study area in the stratigraphic interval of the Middle Devonian (Klintsovski-Mosolovski horizon), Lower Carboniferous (Kosvinski-Radaevski and Bobrikovski horizons) and Middle Carboniferous (Vereyski horizon) systems. The type of organic matter and the degree of maturity of the deposits are established for each stratum. The results can be used in further studies of the hydrocarbon potential of the northern side zone of the Caspian basin and adjacent territories.
