“…11), which keeps consistent in the previous viewpoints. 50,51 This means that both fractal dimensions (D 1 and D 2 ) can be used to effectively evaluate the heterogeneity of pore surface and structure in shale.…”

“…Generally, pore shapes and size distributions can be determined based on experiments and methods including low‐pressure gas adsorption analysis, mercury injection capillary pressure, nuclear magnetic resonance, and field‐emission environmental scanning electron microscopy (FE‐SEM) . Among them, low‐pressure nitrogen adsorption analysis has been proven to be an effective approach to characterize pore structures in shales . If applied over a wide range of relative pressure, nitrogen adsorption isotherms can provide information on size distribution in the micro‐, meso‐, and macro‐porosity range (approximately between 0.5 nm and 200 nm) .…”

“…19,20 Indirect fluid penetration methods, including nuclear magnetic resonance (NMR), helium pycnometry, lowpressure N 2 /CO 2 adsorption and high-pressure mercury injection and mercury intrusion capillary porosimetry (MICP), can be widely used to quantitatively measure the pore structures (specific surface area, pore volume and pore size distribution). 4,[21][22][23] Among these, low-pressure N 2 adsorption and desorption experiments are considered as standard methods for nanoscale pore analysis.…”

“…[23][24][25][26][27][28][29] A large fractal dimension indicates a more complicated pore structure and more rough pore surface. Several pore characterization techniques, including small angle X-ray scattering (SAXS), MICP, FE-SEM and lowpressure N 2 adsorption can be used to calculate fractal dimension.…”
