Annotation:
The prerequisites for the article were the zonal non-confirmation of the geological section by the seismic-geological forecast and, as a consequence, the decrease in the efficiency of the wells horizontal sections drilling.
The problem was solved by a set of measures like petro-elastic modeling and additional processing of the seismic cube (noise reduction, expansion and stabilization of the frequency spectrum), which allowed more qualitative wells routing.
As compared to the geological model of the previous years, the effective penetration using the new model of petro-elastic modeling and additional processing of the seismic cube has increased by 7 %.
