Cover Story: Pore structure features govern the capacity of gas storage and migration in shales and are highly dependent on the types of pores, i.e., interparticle (InterP) pores, intraparticle (IntraP) pores, and organic matter (OM)-hosted pores. On the basis of high-resolution imaging, this work focuses on the distinctive structural and fractal features inherent to pore types and their respective contributions to bulk permeability. Overall, clustered and well-connected pores hosted by OM correspond to the smallest pore diameter and the highest fractal dimension (D), while rounded and scarce IntraP pores translate into the lowest D. A considerable enhancement in overall permeability can be expected when OM-hosted pores interconnect with crack-like pores (e.g., InterP pores) or other effective pore networks. View this paper
