3. Patented AutoFill™ Casing Fill-Up and Circulating System
The AutoFill™ Casing Fill-Up & Circulating System saves time, enhances rig safety,
and well control during drilling operations. AutoFill™ allows the operator to fill,
circulate, and recover fluid while running casing. With the 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.
 Fills or circulates casing as it is being run.
 Our casing circulator is the easiest to operate and the easiest and most inexpensive to
maintain.
 We offer training at our site in Texas as well as on-site training.
 We are presently servicing many of the major casing companies Domestically and Internationally.
The patented AutoValve™ & CF-Series™ Mudsaver Valves are used with the AutoFill™ system to prevent mud from
escaping when the valve is removed from the casing.
