The article is devoted to the development of approaches to the allocation of reservoirs in such a complex object as the Late Jurassic - Early Cretaceous sequences of Western Siberia. Based on the generalization and systematization of laboratory core studies, well logging and field data, the main lithological types of potential reservoirs rocks are identified, their petrophysical characteristics are given, the position in the section and patterns of distribution over the area are determined using the example of the Sredne-Nazym field. The reservoirs are divided into two types: 1st type - rocks with reservoir properties corresponding to traditional reservoirs; 2nd type - poor-porous potential reservoirs that could be involved in development only after technological impacts - hydrochloric acid treatment or hydraulic fracturing. The obtained results are used in planning the development of the Late Jurassic - Early Cretaceous sections, which is currently carried out using horizontal wells.

Keywords: Late Jurassic-Early Cretaceous, lithotypes, well log interpretation results, geochemical studies, Sredne-Nazym field.
