ABSTRACT:
A method of perforating a downhole pipe by cutting at a location within the pipe in a radial direction toward the pipe, producing a determined reaction force, and using the determined reaction force to enhance the cutting of the pipe. The method may include continuing cutting in the radial direction to create an opening in the pipe, and attenuating a pressure wave through the opening.
