1. A method of completing a well in a subterranean formation, comprising the steps of:

  • (a) perforating a first zone in the subterranean formation by injecting a pressurized fluid through a hydrajetting tool into the subterranean formation, so as to form one or more perforation tunnels;

    (b) initiating one or more fractures in the first zone of the subterranean formation by injecting a fracturing fluid into the one or more perforation tunnels through the hydrajetting tool;

    (c) pumping additional fracturing fluid into the one or more fractures in the first zone through a wellbore annulus in which the hydrajetting tool is disposed so as to propagate the one or more fractures;

    (d) simultaneous with step (c) moving the hydrajetting tool up hole; and

    (e) repeating steps (a) through (d) in a second zone of the subterranean formation.
