METHOD OF PROVIDING ENVIRONMENTAL SAFETY OF UNDERGROUND GAS STORAGE Russian patent published in 2016 - IPC B65G5/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to underground gas storage and can be used in gas and oil industry. Method of providing environmental safety of underground gas storage includes its pumping through well, gas storage and extraction from storage, at that in zones of underground arrangement of natural gas is remote environmental monitoring content of methane in surface atmosphere, as well as continuous monitoring of methane concentration in zones of process units. That is followed by prediction of critical at gas concentration zones occurence, which results in zones with high concentration of methane in atmosphere of soil surface is treated with suspension methanetrophic bacteria in salt solution, and in process units of such critical zones additionally elevations of soil are made, into which cyclically at certain pressure and temperature suspension of methanetrophic bacteria in salt solution is pumped.

EFFECT: method provides for environmental safety of underground gas storage, reduced ingress of methane in atmosphere, as well as avoiding greenhouse effect; in period of disturbance of process mode (emergency) it also helps to reduce acuteness of environmental situation.
