The CFT tool was primarily designed to facilitate the management of drilling fluids during a circulation, flow back, and/or fill-up operation while running drill pipe or a liner string. At the customer’s request and when possible, the lower component of the tool can be a Safety Valve which can be connected to the drill string. The operation and use of this Safety Valve is at the sole discretion of the customer/operator.

The primary purpose for the CFT and an ideal application is for use with top drive systems when it is desirable to circulate or take returns from drill pipe. It is possible to use the system on a tubing string as well; however some options such as the safety valve and removal of the outer components may be given up. The purpose of the CFT is to allow a temporary sealing connection to the pipe string without having to make a threaded connection. The CFT allows operation above the pressure rating of the seal and provides a means of reciprocating and rotating the pipe string when a threaded connection is made.

• Makes up to top-drive.
• Tool extends and retracts (pneumatically) over outer diameter of work string.
• Eliminates costly time required to make a top-drive connection.
• Reliable sealing technology for establishing circulation while tripping in or pumping out at hole.
• Simple effective system for managing returns at rig floor.
