FIELD: gas industry; construction and operation of underground gas storage in which gas crossflows are probable. SUBSTANCE: method comes to drilling net of relief wells and differential injection and withdrawal of water. Relief wells are drilled to overlaying formation accumulating the crossflow gas, and gas-and-water mixture withdrawn through the wells is divided into gas and water on surface and then water is again pumped back into permeable formation. EFFECT: improved efficiency of evacuation of gas from overlaying formation. 1 dwg
