Abstract
Criteria for predicting the petroleum potential of ancient deposits of complicated structure with a long evolution history of hydrocarbon pools are considered. They rest on combined stratigraphic, tectonic, lithofacies, geochemical, and hydrogeological data. Detailed prediction of petroleum potential has been made for the Vendian-Lower Cambrian subsalt terrigenous and carbonate deposits of the Vilyuchan, Lower Nepa, Upper Nepa, Tira, Lower Danilovo, Upper Danilovo, and Usol'e reservoirs. Fields different in potential, petroliferous zones, and first-order prospecting objects have been recognized in the areas of their occurrence. Predominant types of traps, pool volumes, and phase compositions of hydrocarbons are predicted. The results will add to the efficiency of search for petroleum.
