Weatherford has announced the commercial release of the PressurePro control system, a fully-integrated rotating control device (RCD) and choke system for wellbore pressure management on land.
The control system combines the SafeShield 5M RCD, which has a 5,000-psi rating, with the PressurePro set-point choke. The system can be used for managed pressure drilling, underbalanced drilling and foam drilling applications.
With semi-automated functionality and a user-friendly interface, the system does not require specialized personnel, continual supervision or manual adjustments. Before drilling, the user inputs the desired pressure set point. Then, during drilling, the system automatically senses changes in downhole pressure and instantly adjusts the choke to maintain wellbore pressure within ±5 psi of the set point.
