ABSTRACT:
A unitary assembly (10); is disclosed for isolating a leak in a side pocket mandrel (12) between the tubing annulus (16) about a tubing string (14) and the interior (20) of the tubing string. The unitary assembly includes an upper packer (22), and a lower packer (24) interconnected by a tailpipe (26). The upper packer (22) is preferably set by a wireline tool and the lower packer is preferably set hydraulically. This eliminates the need for a drilling or workover rig to be setup over the well when patching a leak.
