Abstract
A method for measuring the azimuthal strike orientation of induced fractures in subterranean formations from which the maximum and minimum in situ stress direction can be inferred. The method utilizes an oriented core of a formation and computed tomography imagery for measuring the azimuthal strike orientation of induced fractures.
