Methods and systems for well stimulation using multiple angled fracturing

Abstract

A method for fracturing a subterranean formation, wherein the subterranean formation comprises at least one existing fracture and a wellbore, the method comprising: determining a set of geomechanical stresses caused by the at least one existing fracture, wherein efforts geomechanical They include at least one tangential stress distribution around the wellhead; determining at least one angle of minimum tangential stress around the wellbore based at least in part on the geomechanical stresses caused by at least one existing fracture; and initiating a next fracture in the subterranean formation, where the next fracture is oriented around at least one angle of minimum tangential stress.
