Abstract
This article continues the cycle of scientific publications of “NK “Rosneft” PJSC devoted to the development of the scientific direction in the field of facies modeling of complex geological objects of oil and gas fields within the Russian Federation. The article presents the results of work on the creation of facies models in different stratigraphic complexes of Western Siberia, which served as the basis for localization of the most productive zones and justification for optimizing systems for the development of hard-to-recover reserves. Present the current status of problems in the field of facies modeling and forecasting of inter-well space.

Materials and methods
Materials: data on various types of geological, geophysical and field information studies, including laboratory core studies, petrophysical core interpretation, logging, seismic studies (including results
of inversion transformations and attribute analysis).
Methods: to create a digital facies model, methods of combining core data, logging, seismic studies and various stochastic algorithms
of 3D modeling were used.

Keywords
sedimentological analysis, conceptual model, seismic facies analysis, facies model
