Analysis of Fracture Roughness Control on Permeability Using SfM and Fluid Flow Simulations: Implications for Carbonate Reservoir Characterization

Figure 9

(a) Single-fracture permeability versus opening mode displacement; results indicate a positive power-law relationship (nearly cubic). (b) Hydraulic aperture (computed with the equation (1)) versus the opening mode displacement (mechanical aperture); the relationship follows a positive power law with exponent between 1.6 and 1.8. Axes are in logarithmic scale, and the dashed lines correspond to the best-fitting power laws.
