The article presents the developed method of taking into account the heterogeneity of layers at the stage of designing underground gas storage facilities. The optimal set of methods for studying geological heterogeneity was selected. The application of the developed methodology in the study of the geological structure of the Ugerske and Oparske USG was analyzed. It was established that the productive horizons LD-8, LD-9 of the Ugerske USG and horizon LD-7 of the Oparske USG are characterized by significant variability of parameters (of effective thickness, porosity, permeability, sandiness) on the section and on the area of both structures. A conclusion was made about the importance of taking into account the heterogeneity of the collector layers of depleted gas fields at the stage of designing the gas field, as this will help to more reliably determine the technological indicators that are included in the projects of the operation of the gas field, which will help to avoid significant economic losses and increase the efficiency of underground gas storages.
