The shale reservoirs contain not only a lot of nano-micro scale pores, but the coupling phenomenon between free and adsorbed gas, which leads to complexity when estimating shale-gas production. Currently, different models have been applied to describe the gas transport in shale, especially in different flow regions. However, the role played by adsorbed gas on the production performance is still difficult to evaluate due to the fact that the coupling of free and adsorbed gas is rarely considered.
