Rotating Control Device (RCD)
The primary use of the Pruitt Rotating Control Device 3000 (PRCD 3000) is to serve as a key component during Managed Pressure Drilling (MPD) and Under Balanced Drilling (UBD) operations.
The design incorporates a dual element, drill through bearing assembly for a redundant sealing barrier within the wellbore. The PRCD 3000 forms a passive (wellbore assisted) seal on the drill string and provides the ability to contain pressure within the wellbore while performing normal drilling operations.
The PRCD 3000 comes equipped with the Pruitt Automated Power Unit and Clamp Operating Stand. The Automated Power Unit is designed as a positive pressure system that ensures all fluids and contaminants remain within the wellbore. Positive lubrication is also provided to prolong seal life and provides temperature control for the internal components of the RCD.
The Pruitt High Pressure systems can be used with all Pruitt RCDs. When the time comes to transition from low to high pressure drilling, the process can be as simple as a RCD change, saving hours of rig up-time.
With a static pressure rating of 3000 PSI and an aggressive range of dynamic ratings, the PRCD 3000 provides the necessary range required for MPD/UBD operations employed in the drilling of today's unconventional wells.
