Dover Artificial Lift’s Horn Socket is designed for fishing jobs in small-diameter tubing (1 ¼”, 1 ½” and 1 ¾”) where other sockets cannot be deployed.
Our horn sockets have a lower bowl with integral hard wickers. As the socket is lowered gently onto the catch and rotated to the right, the wickers cut or thread onto the catch. Rod body breaks are caught with conventional wickered slips in the upper bowl.
Because slim-hole couplings are not normally surface hardened, the wickered bowl of the horn socket can be threaded on securely to pull the catch.
In some cases, a 1 ¾” horn socket can be deployed to fish 1 ½” O.D. hardened couplings. However, even if the catch is made successfully, the bowl will likely be damaged. Horn sockets cannot be guaranteed against damage caused by hardened couplings.
