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.
