The characterization of flow properties for shale gas reservoirs is of importance but is more complex than for conventional petroleum reservoirs. The complications arise from the tightness of pore space and the diverse chemical compositions of the matrix as well as nonDarcy flow processes taking place within pore space. All these pose real challenges to develop reliable and robust laboratory core measurement techniques. Digital core analysis is shown to have potential to compliment laboratory measurement techniques. This chapter summarizes some of the work on developing digital core analysis technology for flow characterization of gas shale and on assessing the impact of slip flow, Knudsen diffusion, and gas adsorption on the permeability of free gas.
