Annotation:

The article presents the results of geological exploration work based on the seismic survey data within the Yen-Yakhinskaya area, on the basis of which a 3D hydrodynamic model of the field was built. When developing a field, the results of modeling are refined by using field data, in particular, hydrodynamic studies systematically performed on the producing well stock. These studies can be a reliable source of information for clarifying the geological structure of productive deposits. Thus, the bottomhole pressure recovery curve allows refining the filtration parameters of both the reservoir (permeability, hydraulic conductivity, piezoelectric conductivity) and its bottomhole part (skin factor value).
