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 drilling.
The system can be used for managed pressure drilling, underbalanced drilling and foam drilling applications.
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.
By automating choke adjustments, the system reduces the number of people on the rig floor and improves health, safety and environmental outcomes.
