Abstract:
A method for perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore, said method comprising:(a) deploying a bottom-hole assembly (â€œBHAâ€ ) using a deployment means within said wellbore, said BHA having a perforating device and a sealing mechanism; (b) positioning said BHA within said wellbore using a depth-control device; (c) using said perforating device to perforate said interval; (d) actuating said sealing mechanism so as to establish a hydraulic seal in said wellbore; (e) pumping a treating fluid in said wellbore and into the perforations created by said perforating device, without removing said perforating device from said wellbore; (f) releasing said sealing mechanism; and (g) repeating steps (b) through (f) for at least one additional interval of said one or more subterranean formations.
