Product - Ridged StabberLess AutoFill FACT

The StabberLess AutoFill System  is designed to facilitate filling, circulating, and flow back when there is no stabber in the derrick and to reduce the time required to run casing, and allowing immediate circulation in case of well problems. The system allows the rig pumps to be used in the fill-up process while making up and running each joint of casing. This tool hangs inside the elevator to allow easy stab in operation and is widely used in the Gulf of Mexico.

Safety is greatly increased when using a StabberLess AutoFill System without the need to have an operator in the derrick.

The StabberLess AutoFill System can run on top drives & conventional rigs with hooks. The conventional rig adaptor and mud hose assembly is sold separately.

The C-Series Valve provides an internal valve that opens when you begin pumping. The valve will close when the pumps are stopped to prevent fluid from dripping on the rig floor. This valve also has a large flow-back area to facilitate running a liner or casing string with an open ended or flow back float shoe.

The StabberLess AutoFill Casing Fill-Up and Circulating System saves time and enhances rig safety and well control during drilling operations by allowing the operator to fill, circulate, and recover fluid while running casing. With the StabberLess AutoFill Casing Fill-Up and Circulating System, you can continue to use the rig pumps and top drive while running or pulling each joint of casing.

The patented C-Series MudSaver Valve is used with this system to prevent mud from escaping.
