Method and apparatus for stimulation of multiple formation intervals

A stimulation treatment sytsem for use perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore, said system comprising:

• (a) a treating fluid
• (b) a deployment means selected from the group consisting of a wireline, a slickline and a cable deployed within said wellbore;
• (c) a bottom-hole assembly (BHA) adapted to be deployed in said wellbore with said deployment means, said BHA having a least one perforating device, for sequentially perforating said multiple intervals, and at least one sealing mechanism, said BHA capable of being positioned within said wellbore, to allow actuation of said perforating device and said sealing mechanism;
• (d) said sealing mechanism capable of establishing a hydraulic seal in said wellbore, and further capable of releasing said hydraulic seal to allow said BHA to move to a different position within said wellbore, thereby allowing each of said multiple treatment intervals to be treated with said treating fluid separately from said other treatment intervals.

An apparatus for use in perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore, said apparatus comprising:

• (a) a bottom-hole assembly, having at least one perforating device for sequentially perforating said multiple intervals, at least one sealing mechanism;
• and at least one tractor device;
• (b) said tractor device capable of positioning said BHA at different positions in said wellbore;
• and
• (c) said sealing device capable of establishing a hydraulic seal in said wellbore, and further capable of releasing said hydraulic seal to allow said BHA to move to a different position within said wellbore, thereby allowing each of said multiple treatment intervals to be treated separately from said other treatment intervals.

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 selected from the group consisting of a wireline, a slickline and a cable within said wellbore, said BHA having a perforating device and a sealing mechanism,
• (b) using said perforating device to perforate said interval;
• (c) actuating said sealing mechanism so as to establish a hydraulic seal in said wellbore;
• (d) pumping a treating fluid in said wellbore and into the perforations created by said perforating device, without removing said perforating device from said wellbore;
• (e) releasing said sealing mechanism, and
• (f) repeating steps (b) through (e) for at least one additional interval of said one or more subterranean formations.
