BR-T2 on-off tool used for the tubing string to be disconnected above a packer for zonal isolation, tubing retrieval, and temporary zone abandonment. The tool has an internal lock profile for landing a wireline plug for providing zonal isolation below the packer.
The tool consist of basic components, the overshot mounted on the tubing string and the stinger body mounted on the packer. The overshot disengages with either a standard left release or an optional right quarter-turn release. The wash over shoe on the overshot cuts through debris allowing for easy engagement of the stinger. The seals in the tool are retrieved with the overshot to enable redressing at the surface.
Available with all common wireline profiles, the stinger works with industry-standard blanking plugs, standing valves, and regulators.
Features:
- The tool enables the packer to be used as a bridge plug for zonal isolation.
- The temporary abandonment of zones, saving rig costs.
- The tool can be full-pressure tested at the surface to save rig time.
- If specified at time of order, the tool can be pinned in a shear-up or shear-down.
- position, providing compatibility with the packer setting and retrieving style.
- The standard left or optional right quarter-turn release provides simple operation on the rig.
- Bonded seals enable multiple disconnections without costly retrieval.
