Abstract:

A method of fracturing a subterranean formation having a well bore extending thereinto. The method comprises the steps of: (a) placing a jetting tool in the well bore such that the jetting tool is positioned within the subterranean formation, the jetting tool including a jetting nozzle; (b) orienting, by rotating the jetting tool about a longitudinal axis, the jetting tool such that the directional orientation of the jetting nozzle substantially corresponds to a predetermined fracturing direction; and (c) cutting a slot in the subterranean formation (and/or casing) by substantially maintaining the jetting nozzle orientation established in step (b) while both (1) spraying a jetting fluid out of the first jetting nozzle and (2) moving the jetting tool longitudinally within the well bore along the longitudinal axis.
