... simulated absolute permeability (2.0×10 -12 m 2 ) is much higher than the matrix permeability (6.7×10 -20 m 2 before the interaction; 1.3×10 -19 m 2 after the interaction), as calculated based on the Kozeny–Carman Equation. This indicates that natural fractures provide preferential flow paths for CO 2...
