A device and method for perforating a casing without the use of explosives or a mechanical apparatus is disclosed. A perforating sleeve can be fit to a tubing string and run downhole to be positioned adjacent a portion of a hydrocarbon formation. Embodiments of the perforating sleeve can have at least one port which contains a chemical cutting agent and a catalyst. A ball can be dropped from the surface to actuate the perforating sleeve for causing the catalyst and the chemical cutting agent to come into contact with one another for perforating the casing. By the utilization of the chemical cutter described herein the decision on the type of completion equipment to be implemented may be delayed or modified as the well creation progresses. |
