..., and the fracture propagation direction becomes controlled by the specimen heterogeneity. Recent field evidence by coring through a stimulated rock volume (SRV) in the Eagle Ford Shale showed the formation of complex fractures despite the sparseness of pre-existing fractures in the cored sections of the SRV. Using...
