Abstract

The article explores the significant resource potential of the Vikulov suite. The results of the application of various methods of processing and interpretation of granulometric analysis materials are summarized: the generalized diagnostics of the sedimentation situation according to G. Fühtbauer and K. Müller, the evaluation of the genesis of the deposits by the sorting ratio and the asymmetry features (K. Bjerlkeke diagram), the identification of sedimentation conditions by the correspondence of asymmetry and kurtosis (dynamogenetic diagram of G.F. Rozhkov), establishing the method of transport of detrital particles in an aquatic environment (R. Passage's genetic diagram). A detailed analysis of the sediments made it possible to identify four main rock lithotypes within the upper reservoir of VS 1, located at the boundary of a sharp change in paleofacial environments, some of which are associated with oil and gas potential in the West Siberian sedimentary-rock basin.
