Abstract
During fracture treatment of a subterranean formation, multiple hydraulic fracturing cycles are performed wherein the bottomhole treating pressure of a wellbore is controlled to not exceed a maximum bottomhole treating pressure for the formation, thereby attaining maximum principle fracture extension and limiting initiation of secondary fractures transverse to the principle fracture extension.
