Analysis of Sorption-Induced Permeability Reduction Considering Gas Diffusion Phenomenon in Coal Seam Reservoir

The sorbed gas diffuses in a coal matrix, where diffusion varies considerably with pore structure and pressure. The diffusion is an essential factor due to high sorption affinity of

CO2 on coal grain surface. The sorption within the matrix causes swelling or shrinkage of matrix, in which the amount of sorbed gas affects gas diffusion. In this study, in order to observe permeability change occurred when the sorbed gas diffuses in a coal matrix, experiments were conducted with a bituminous coal sample. Firstly, gas partial pressure was measured through a diffusion experiment with a transient flow method. Secondly, flowing experiments were conducted to examine the permeability reduction yielded by sorption phenomena according to the various pore pressures. The results were then analyzed for the effect of diffusion coefficient on permeability change. The diffusion coefficient of
