1. 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 (“

    BHA”

    ) 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.
