The heavy duty hydraulic disconnect (HDHD) allows the tool string to detach at a predetermined point via the deployment of a suitable drop/trip ball through the coiled tubing. The drop ball locates on a piston sleeve, creating sufficient back pressure to shear the pins and disconnect the tool. When this happens, the piston sleeve pushes the tool apart to ensure a clean disconnect, and circulation is immediately returned to the tool string, providing a surface indication of a positive disconnect. All piston sleeves and drop balls are returned to the surface, leaving a standard GS internal fish neck for retrieval purposes.
