The Hunting Drilling Disconnect is a robust, 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 stuck drill bit or BHA. The tool can accommodate straight pull and torque loads without affecting the release mechanism.

The Drilling Disconnect is a cost effective, three-piece design, consisting of a Latch Sub, Piston and Housing. To release, a ball is dropped to seat on the top of the piston. At a predetermined pressure the shear screws will shear allowing the piston to move down and disengage the latch. A minimal over pull is required to release the latch allowing the drill string to be retrieved. The Housing, which is left in hole, has a substantial fishing neck left looking up for retrieval with a die collar or other fishing tools.

The tool can be fitted with a burst disc in the Housing in order to re-establish circulation if required.
