In the material balance process, gas storage mechanism is part of the history of the reservoir. It is important to know how the gas is stored before producing it. For shale gas, there are three possibilities: 1. Most of the gas (>50%) is adsorbed on the shale matrix and remaining is stored in the matrix. 2.
