Abstract
In accordance with some embodiments of the present disclosure, a geomechanical model of the stresses on an orthorhombic media for use during a subterranean operation is disclosed. The method includes retrieving a stiffness coefficient matrix for a formation to be fractured and generating a geomechanical model of the formation based on a set of natural fractures and an anisotropic behavior of the formation. The method additionally includes calculating a mechanical property of the formation based on the model and the stiffness coefficient matrix. The method further includes fracturing the formation with a fracturing fluid, a pressure of the fracturing fluid based on the mechanical property.
