A Review on Underground Natural Gas Storage in Other Countries Iran

Underground gas storage (UGS) is a universally common method for compensating shortages of natural gas and its excess use in cold seasons.To stores the gas, two ways are usually used: base load and peak load storage. There exsists three kinds of reservoirs for storing natural gas: storing in depleted oil (gas reservoirs), aquifer reservoirs, and in salt domes. It is easier and cheaper to use depleted oil and gas reservoirs for sharing natural gas. In this article, the situation of natural gas storage in Iran and the world and its prospect in the future are generally studied. In addition different parts of a storage site and its designing factors are introduced. Evaluation and performance of different reservoirs for storing gas is discussed depended on three parameters: potential gas accumulation, gas untransporting ability and ability of reproducing. At last the situation of natural gas storage projects in Iran containing the gas storage in Qom, Khangiran and some others fields have been pointed.
