The Work Over Drill Pipe Circulator (WODPC™) is designed to be remotely controlled from the rig floor or on the ground next to the work over rig. The unit is used to connect to or disconnect from tubing or drill pipe tool joints.

The Work Over Drill Pipe Circulator, or WODPC™, can circulate, pump in/out of the hole, and expand casing. This tool makes it practical and saves time in pumping and circulating on work over rigs.

The WODPC™ is mounted on one bail and is connected to the mud system and pneumatic control panel. The system consists of 4 components:

  1. Control Panel
  2. Support Arm
  3. Tool Joint Air Motor
  4. Hose Assembly

The Control Panel is used to articulate the Air Motor over the tool joint & make a 10,000 PSI connection less than 15 seconds. Once the system is sealed to the tool joint, fluid can be circulated through the pipe, while tripping in and out the hole.

The system can be used at high pressures to expand casing and can be utilized for other applications.
