Abstract
Methods and apparatus are presented for mechanically perforating a tubular positioned in a subterranean wellbore. A plurality of punch members are moved radially outward in response to hydraulic pressure from the tubing or other source into contact with the tubular. Retraction of the punch members is by biasing member or change in hydraulic pressure. A slip assembly, also hydraulically actuated, secures the tool in position during use.
