Geochemistry of oils in the central part of Volga-Urals petroleum province, composition and distribution of biomarkers are considered. The principal distinction between two genetic oil groups is related to different lithology of their source rocks. The linkage between one of the oil groups with Middle Frasnian and Upper Frasnian-Tournaisian “domanic” deposits is shown. Pyrolysis data permitted estimation of amount of hydrocarbon expulsion from “domanic” source rocks.

Key words: genetic typification of oils, biomarkers, petroleum potential, hydrocarbon expulsion, Volga-Urals petroleum province.
