Abstract
Summary
When constructing a three-dimensional geological model, one of the main stages is the construction of a conceptual model of the field using the methods of facies analyses. In determining sedimentation and facies environments along the Tanopchinsky series, well data were used (core, logging curves). Depending on the facial conditions, different types of channels are formed, which, in turn, form sand bodies that are different in shape and size. When mapping facies zones, various seismic attributes were used. The method of spectral decomposition made it possible to trace most effectively the ancient channel systems and channels through which the material was transported and to predict the zones.
