Most of the fields associated with Upper Jurassic-Cretaceous deposits of the West Siberian Petroleum province are already discovered. Therefore, further possibilities are related to the basal levels of sedimentary cover and upper part of pre-Jurassic sequence. However, there deposits occur deeply and have an extremely complicated geological structure. In this situation, in addition to expanding the scope of exploration works, improving their efficiency is of great importance, which is supported by reliability of geological model of a pool. One may achieve consistency of a model by involving all types of geological and geophysical data in its construction and by using correct and efficient methods and techniques of integrated interpretation of heterogeneous and multiple-scale information. This purpose requires an integrated approach to analysis core, well logging data, seismic data processing and interpretation, where a conceptual geological model of the object under study should be used as the basis. This paper discusses the studied pay zone having the considerable petroleum production potential, namely, the upper part of pre-Jurassic sequence in the North Varyogansky field. Application of geosystems approach to analysis of core studies data, well logging data, seismic data processing and interpretation allowed creating a detailed geoseismic model of the object.

​

Key words: conceptual model; geosystems approach; pre-Jurassic sequence; seismic data; simultaneous inversion; elastic properties.
