Abstract
Large gas reserves have been discovered in the Vendian terrigenous rock complex of the Angara-Lena step in the southern Siberian Platform. In recent years, regional and areal exploration has yielded substantial data on the structure of gas-promising sedimentary strata and their reservoir properties. The author has analyzed the main structural features of Vendian gas-producing deposits and has made deterministic and probabilistic evaluation of initial hydrocarbon resources with regard to the discovered-field reserves.
