AutoFill

StabberLess AutoFill 

Casing Fill-Up and Circulating System

Fills or circulates casing as it is being run

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.

When using a StabberLess AutoFill  System with no man in the derrick, the safety aspect increases greatly.

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.

Features & Advantages

Push Plate This assembly provides for a “false” shoulder for the casing to hit should the casing begin to float or should you hit an obstruction while running the casing string. Should the elevators become difficult or impossible to release, the Push Plate can be moved upward allowing the traveling block and elevators to be lowered and the elevator slips to be released. Plus you can use the Push Plate to push threw tight spots and keep from getting the casing stuck.
Spacers For accommodating 8’ to 24’ long Bails and different Top Drives.
Sealing Unit Allows the unit to Seal to the casing allowing you to perform Fill-Up, FlowBack & Circulating Job
C-Series Valve This valve keeps the mud or circulating fluid from spilling out of the unit. It also give the option to take flow back, fill up, and circulate at any time.

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™ Valve Mudsaver Valve is used with this system to prevent mud from escaping.
