Fracture evaluation is an integrated stress over a highly stressed region near the crack tip, is a material property independent of the loading rate. Fracture toughness can be predicted from the static toughness results. Evaluation of fractured reservoirs traditionally involves the identification and orientation of the fractures. Fractures are newly characterized by scribing only the fracture surface present along the image contact. Correcting the fracture scribe for the percentage of image coverage, a petrophysical log curve can be derived using a standard window size.
