The article presents an analysis of the peculiarities of the exploitation of the underground gas storage system, and an assessment of the flexibility of the current supply for the consumption of underground water supply. At the same time, the main factors have been detected, which are used to inject gas into the filter paramters of the pre-shaped zone and the formation of the upper holes in the process of exploitation of the subterranean groove. It has been established that when gas is pumped underground, the technogenic obstruction of the collector with compressor olive oil and solid particles is added to the reservoir zone with gas. The technology of purification of the pre-vibration zone and the formation by means of filthy active acid breaks has been promoted, during testing it has shown a high efficiency. The developed technology is of practical importance for underground hydrogen storage, as the main factors affecting the productivity of wells are common to underground storage of gas and hydrogen. Experimental studies and accumulated experience confirm that it is possible to use porous water-saturated formations or reservoirs of flooded oil and gas deposits as geological objects for gas storage.
