“…Flow properties of fractured materials are strongly stress-and scale-dependent. Important factors include porosity and pore size distribution (Heap and Kennedy, 2016;Kim and Makhnenko, 2023b), testing conditions including the way to set up the fractured specimen (Bondarenko et al, 2022), thermal effect especially important for shales (Mohajerani et al, 2012;Makhnenko et al, 2023), and time-dependent deformation that is not only strongly pronounced for clay-rich rock, but also is enhanced for fractured materials (Makhnenko and Podladchikov, 2018;Zhu et al, 2023). At the field scale, fractured rock is reported to have a few orders of magnitude larger permeability compared to the intact material tested at the laboratory scale (Neuzil, 1986;Heap and Kennedy, 2016;Azizmohammadi and Matthai, 2017).…”
