Precisely Managing Pressure
Myth: Enhancing safety without sacrificing efficiency is unachievable.
Truth: Automated closed-loop circulating systems enhance both safety and efficiency.
Let’s talk about the truth.
Weatherford presents the third topic in a series of four Oil & Gas Journal articles:
While manual managed pressure drilling (MPD) methods regularly operate safely and effectively, an automated system provides enhanced precision and timely action to address unplanned events.
Manual operations involve interpreting data and then reacting manually. Automated systems use internal algorithms to identify what is occurring in the wellbore and apply an automatic response. The speed and accuracy facilitate optimal pressure management to significantly enhance safety and performance.

Tactical Technology™: Microflux™ MPD Control System
Microflux™ MPD Control System
Weatherford’s Microflux MPD Control system leverages proprietary algorithms to detect minute fluid influxes or losses and reacts automatically to its interpretation of wellbore conditions.
One key element is a control-loop feedback mechanism that is tailored to characterize the MPD equipment and capable of adaptation to changing dynamics such as mud systems, well compressibility, drilling windows, and surface equipment limitations.
These capabilities produce even greater safety and efficiency advantages than manual MPD systems.
Ultimately, the Microflux system makes undrillable wells drillable.
Truth in Action: Precisely Managing Pressure
The automated Microflux MPD control system played a critical role in a high-pressure, high-temperature environment with a very narrow pore pressure and fracture gradient window. Operations involved circulating out up to 50% gas cut mud and preventing kicks, lost circulation and differential sticking. The system successfully detected and controlled an influx of less than 1.5 bbl within two minutes.
