The BT Circulating Disconnect is a compact Tool String which incorporates two features. These features include a Ball activated Disconnect facility and a Dual Operation Circulating Sub. The Tool also features a torque through facility as well as a standard internal GS Fishing Neck profile. The Disconnect facility is there to provide a means of disconnecting from a stuck Tool String by simply dropping a Ball.
The Circulating Sub introduces a flow path from the tool ID to the annulus. However, if for any reason circulation through the Tool String is lost, an Overpressure Activated Piston is featured.
The Tool can be supplied with a specified Connection up or a variety of styles of Coil Connector.
