HYDRAULIC DISCONNECT

HYDRAULIC DISCONNECT

The Hydraulic Disconnect allows the toolstring 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. All piston sleeves and drop balls are returned to surface leaving a standard ‘GS’ internal fish neck for retrieval purposes.
