A method of inducing fracture complexity within a fracturing interval of a subterranean formation comprising characterizing the subterranean formation, defining a stress anisotropy-altering dimension, providing a wellbore servicing apparatus configured to alter the stress anisotropy of the fracturing interval of the subterranean formation, altering the stress anisotropy within the fracturing interval, and introducing a fracture in the fracturing interval in which the stress anisotropy has been altered. A method of servicing a subterranean formation comprising introducing a fracture into a first fracturing interval, and introducing a fracture into a third fracturing interval, wherein the first fracturing interval and the third fracturing interval are substantially adjacent to a second fracturing interval in which the stress anisotropy is to be altered.
