“…In the study by Cui et al, the matrix permeability/diffusivity of crushed samples with a certain mesh count was determined using late-time data. This method was widely used for the characterization of matrix permeability and/or diffusivity of mudstones, especially for fine-grained rocks. ,, In this study, we extend their method to the core scale to characterize the gas diffusivity of stress-loaded cores. In this study, helium and methane are used to measure diffusivity.…”

“…Fractures might be naturally-or artificially-induced (e.g., created during sample processing), which makes a comparison of permeability results among different samples difficult (Heller et al, 2014). Hence, methods for measuring the matrix (non-fractured) permeability in tight media, with a practical necessity of using granular samples, have attracted much attention to eliminate the confounding effect of fractures (Civan et al, 2013;Egermann et al, 2005;Heller et al, 2014;Wu et al, 2020;Zhang et al, 2020).…”
