On-Off Seal Unit

The On-Off Seal Unit is a short, compact, overshot type receptacle with a Jay, which engages automatically and releases with a one quarter turn left hand rotation.

When mounted above a locking type packer, this tool provides a means of disconnecting the Tubing String in order that remedial work can be performed without unseating the packer. A profile in the Seal Mandrel provides a means of blanking off the zone below the packer with a Wireline Retrievable Plug. After remedial work has been completed, the tubing may be re-engaged at the On-Off Seal Unit and the Tubing Plug pulled by wireline to place the well on production.

A Washover Shoe on the Overshot allows rotation through sand and other debris. Easy re-engagement of the tool and packer removal are enhanced by the short mandrel length, which allows for maximum washing action. The plug profile located in the upper part of the mandrel allows for circulation of debris off of the plug.

The On-Off Seal Unit is available with right hand release for special applications - all common wireline profiles - and a molded seal to allow for multiple disconnections without seal damage.

Operation

The On-Off must be in a fully compressed position to disconnect. Applying left hand torque to the tubing moves the tubing upward. To reconnect set down on the tool and the On-Off will automatically relatch.
