Abstract:
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) injecting a fracturing fluid into the one or more perforation tunnels so as to create at least one fracture along each of the one or more perforation tunnels; (c) moving the hydrajetting tool to a second zone in the subterranean formation; (d) perforating the second zone by injecting the pressurized fluid through the hydrajetting tool into the subterranean formation, so as to form one or more additional perforation tunnels; (e) injecting the fracturing fluid into the one or more additional perforation tunnels so as to create at least one fracture along each of the one or more additional perforation tunnels; and (f) plugging at least partially the one or more fractures in the first zone with an enhancing isolation fluid; wherein step (c) is performed before steps (d) and (e); and wherein step (d) is performed before step (f).
