Patent number: 11156071Abstract: A system and method of wellbore operations that forms notches into a subterranean formation that circumscribes a wellbore prior to fracturing the formation. The notches extend past the hoop stress regime that surrounds the wellbore so that fractures formed by fracturing are oriented in a designated plane.
