Abstract
A non-explosive punch system for making perforations in a casing includes a housing and one or more punch elements configured to extend through a wall of the housing to perforate a casing of the well. An actuating device is located within the housing and may comprise a piston and an actuator block configured to actuate the one or more punch elements. An energy supply device is also located within the housing and may comprise a valve to direct fluid flow and a piston configured to use a pressure of a well fluid present in the casing, to actuate the actuating device. No explosive material is present in the punch system.

A non-explosive punch system for making perforations in a casing, the non-explosive punch system comprising:
- a housing extending along a longitudinal axis and configured to be deployed in a well;
- one or more punch elements configured to extend through a wall of the housing to perforate a casing of the well;
- an actuating device comprising a piston located within the housing and configured to actuate the one or more punch elements;
- and
- an energy supply device comprising a valve located within the housing and configured to selectively direct pressurized fluid to the piston,
- wherein there is no explosive material.
A method for manufacturing a non-explosive punch system for making perforations in a casing, the method comprising:
- providing a housing extending along a longitudinal axis and configured to be deployed in a well;
- adding one or more punch elements to the housing, wherein the one or more punch elements are configured to extend through a wall of the housing to perforate a casing of the well;
- installing within the housing an actuating device comprising a piston configured to actuate the one or more punch elements;
- and
- fluidly connecting an energy supply device comprising a valve to a well fluid present in the casing and to the piston,
- wherein there is no explosive material.
