The Rebco Mechanical Tubing Perforator is a mechanical wireline-deployed tool designed to create flow ports through the wall of the production tubing at a specific depth without the use of explosive or shaped-charge perforating systems. The perforator mechanically drives a hardened punch through the tubing wall using downward jarring force, creating a controlled hole of precise diameter. This technique is used when communication between the tubing bore and the tubing-casing annulus is required, for example, to establish flow paths in a portion of the tubing that is no longer contributing to production, to create injection entry points for chemical treatment, or to establish pressure equalization ports in an isolated zone. The tool string must include adequate stem weight and a robust jar system to generate sufficient punch-through force, which varies with tubing wall thickness, grade, and OD. Multiple perforations can be placed at different depths in a single trip by running the tool to each target depth and reactivating. Tubing Perforator Stops (see below) are used in conjunction with the Tubing Perforator to control and limit the depth placement of each perforation.
