1. A method for generating a fracability model of a subterranean formation, the method comprising:
coring and collecting rock cores from a plurality of geographical locations in the subterranean formation, wherein each of the rock cores comprises artificial fractures produced when applying stress by a coring bit to downhole rocks to collect the rock cores;
capturing a plurality of core images of the rock cores that are brought to the Earth's surface;
generating, by a computer processor and based on the plurality of core images, a plurality of artificial fracture counts of the rock cores, wherein the plurality of artificial fracture counts are generated by counting the artificial fractures in the plurality of core images captured from the rock cores at the Earth's surface using an artificial intelligence (AI) fracture model that recognizes and counts the artificial fractures;
computing, by the computer processor and based on the plurality of artificial fracture counts, a first fracture density curve corresponding to a first geographical location of the plurality of geographical locations;
generating, by the computer processor and based on the first fracture density curve, a first fracability measure curve of the rock cores; and
generating, by the computer processor and based at least on the first fracability measure curve, a fracability model of the subterranean formation.
