Quantitative Assessment of Oil-Bearing Prospects of High- Carbon Shale-Like Strata

Summary Hydrocarbon accumulations in high-carbon shale-like strata are not controlled by the structural plan and do not contain bottom water and edge water. These features require the appliance of unconventional methods of resource evaluation in such strata. The paper observes the method of estimation of undiscovered potential resources on the basis of geochemical data. A comparative analysis of the results of the calculation of geological oil reserves in the deposits of domanik type (one of the objects of Buzuluk depression) showed a good precision of the results with the traditional volumetric method.
