Abstract
A computer-implemented method for determining fracture roughness from a core is described. In examples, a drill core is scanned to obtain core images, and natural fractures in the core images are identified using sequential filtering. The identified natural fractures in the core images are digitized and used to obtain a fracture profile comprising a pair of sinusoids corresponding to the top wall and the base wall of the identified natural fractures. A best fitting sinusoid of the fracture profile is determined and used to calculate at least one statistical estimator. The calculated statistical estimator is used to calculate a joint roughness coefficient.
