Secondary porosity of reservoirs, characterized by the appearance of large caverns and a system of cracks in rocks, is the main search feature for the identification of highly productive objects in carbonate sections in oil and gas fields. As a rule, the distribution of reservoirs with secondary porosity is extremely uneven over the area of the deposit and in the section. Oil and gas companies spend large financial resources to localize such zones in order to increase the efficiency of field development [1,2,3,4]. One of the most effective tools for isolating highly productive reservoirs in carbonate sections is the method of detailed. Processing and inversion of three-dimensional seismic data. However, as practice has shown, in the case of a sharp variability in the thickness of the studied object, the efficiency of seismic exploration decreases, and the probability of an inhomogeneous stress-strain state of the rock mass increases significantly. Consequently, there is a need to develop new methods for identifying highly productive zones.
