ABSTRACT:
The tool is a mechanically operated detonating device that is actuated by tension. The device is run into a hole on a slick line or tubing and latched. When a predetermined upward pull is provided on the supporting line, a firing pin is released and fires an initiator. Typical uses are perforating, cutting and setting plugs in casing, tubing and drill pipe. Additional tension thereafter applied can be used for recovering the tool or a major portion thereof from the hole, on the supporting line.
