μX-CT image of four core samples used for permeability tests. a Original images sliced in the vertical direction relative to the flow direction. The sliced images for Cores 5R1, 27R2, and 8L8 are parallel to the bedding, and the image for Core 15R3 is perpendicular to the bedding. b Modified sliced images of the cut section, shown as a broken line in (a), parallel to the flow direction. c Binary images of (b), adjusted based on initial porosity data
