The BT Heavy Duty Disconnect is a torque through Disconnect that is released via a Drop Ball and hydraulic pressure. This Tool enables the operator to drop a Ball and pressure up in order to disengage from a fish or BHA. The Tool can handle straight pull, impact, jarring and torque loads without affecting the release mechanism.
The drop Ball lands out on a Ball Seat, when pump pressure is applied, Screws shear allowing the Release Piston to move down, releasing the Collet Fingers thus allowing the upper half of the assembly to be retrieved to surface. A standard internal Fishneck is left looking up for future retrieval operations.
The Connections on the Subs are manufactured to suit BHA requirements.
