The Rotating Tubing
Hanger.
The Rotating Tubing Hanger is designed to replace the conventional stationary tubing hanger on rod pumped wells
and wells pumped with a Progressive Cavity Pump. The tubing string is rotated during pumping.
The Rotating Tubing Hanger utilizes a gear driven Hanger mandrel to carry the weight load of the tubing string. The weight of the tubing string is carried by a bearing system through the body of the
Rotating Tubing Hanger into the tubing head and casing.
The unit comes complete with a Rotating Surface Swivel installed. This swivel fits between
the Rotating Tubing Hanger and pumping/flow tee. The Rotating Surface Swivel is designed to accommodate the heavy rod loads associated with Progressive Cavity Pumps. The Rotating Surface Swivel also uses a bearing system to handle side loading. This makes it ideal for use on "Slant
Wellbore" installation.
The Rotating Tubing Hanger is powered by the movement of the pumping unit. No auxiliary power source is required, nor is there any additional energy consumption
on the pumping unit. The Rotating Tubing Hanger can be powered by an electric drive system or a hydraulic drive system when used with Progressive Cavity Pump Systems.
Rotating of the tubing distributes
the wear that occurs at the point of contact between the rods and tubing throughout the entire
360° of the tubing ID, thereby greatly extending the production run
time between tubing failures. The extended tubing life gained from tubing rotation will allow additional cost savings from the use of less expensive thin wall tubing. Tubing rotation can increase the effectiveness of corrosion inhibitors and can eliminate downhole paraffin problems. Rotation of the tubing string can eliminate many of the problems associated with rod guides such as drag, float, and cyclic loading of
the rod couplings.
The Rotating Tubing Hanger system will prevent the build up of solids such as calcium chloride, salt
and scale on the OD of the tubing. This can prevent costly washovers during pulling operations.
Rotating Tubing Anchor/Catcher
allows the entire tubing string including the gas/mud anchor, tailpipe, and seating nipple to rotate while pulled into tension.
