Abstract:
1. A method of completing a well in a subterranean formation, comprising: providing a hydrajetting tool disposed within a well bore in the subterranean formation; injecting a fluid through the hydrajetting tool into a first region of the subterranean formation at a velocity sufficient to form one or more perforation tunnels in the first region; moving the hydrajetting tool to a second region of the subterranean formation while flowing a fluid continuously through an annulus between an outer surface of the hydrajetting tool and a wall of the well bore into at least one of the one or more perforation tunnels in the first region at a pressure greater than the fracture closure pressure, so as to create one or more fractures in the first region; flowing a fracturing fluid down the annulus to extend at least one of the one or more fractures in the first region; plugging at least partially at least one of the one or more fractures in the first region with an isolation fluid while injecting a fluid through the hydrajetting tool into a second region of the formation at a velocity sufficient to form one or more perforation tunnels in the second region; and flowing a fluid continuously through the annulus into at least one of the one or more perforation tunnels in the second region at a pressure greater than the fracture closure pressure, so as to create one or more fractures in the second region.
