The Effect of Gas Leaks on Underground Gas Storage Performance During Development and Operation

Underground gas storage is an efficient tool for matching the constant supply of gas to the variable demands of the market. Gas escaping from a storage field may cause environmental and safety problems. We present a physical simulation together with actual field data to evaluate the caprock of underground gas storage in the Jing-Bian area. The effect of gas leaks on the performance of gas storage is analyzed by using the type curves of the injection-withdrawal cycle.
