The PowerAMPS(tm) Automated Managed Pressure System, a product developed by the Power Chokes division of PowerWell Services, addresses many long-standing drilling and wellbore stability-related issues.
These issues are the elimination of pressure surges when stopping/starting circulation, improved drilling fluid management, enhanced ECD control, improved hole conditions, and perhaps most important, the ability to drill more efficiently within narrow pressure environments.
The PowerAMPS(tm) System, a continuous circulation variation of MPD 
technology, is fed data by a hydraulics well-modeling program that reads and processes data (such as RPM of the drillstring, ROP, drilling fluid viscosity, density and temperature, etc.) and then predicts the annular pressure profile. Once the desired pressure profile has been determined, PowerAMPS(tm) automatically modulates the choke, making micro-adjustments as necessary, to compensate for changes in the annular friction pressure as annular flow rates increase or decrease.
The PowerAMPS(tm) System provides better control of the well and achieves more precise wellbore pressure management, containment and diversion of mud returns with fewer interruptions to the drilling process.
