Abstract:
This invention relates to a wireline tractor (10) for use in a casing or tubing (4) in a well. The wireline tractor (10) includes at least one retractable wheel (14) for driving within the casing or tubing (4) and a rotatable disc-shaped cutting device (11) mounted on an actuator (13) that is coupled to the wireline tractor. The cutting device (11) and the actuator (13) are configured for pressing the cutting device (11) against a wall of the casing or tubing (4) and for cutting a perforation (100) in the wall of the casing or tubing (4), in operational use of the wireline tractor (10). The invention further relates to a method for perforating a casing or tubing (4) in a well.
