Simulation of Underground Gas Storage Feasibility in a Depleted Gas Reservoir

Underground storage of natural gas is an inevitable necessity because of increasing growth of household energy consumption, the high share of natural gas in the energy basket, high costs of development of production resources, and refining. Considering the growth of demand and variation of natural gas consumption as a massive and inexpensive energy carrier, also unbalanced supply and demand for natural gas in cold seasons, there is a need for natural gas storage for preventing lack of gas during peak gas consumption. In this way, extra gas is injected into the underground reservoir during storage in summer and taken from that reservoir in the cold seasons. The creation of underground reservoirs for storing natural gas is scheduled to be implemented by the gas storage company and the vulnerability of the transmission and distribution system will be prevented by storing surplus gas in summer for reprocing in winter.
