WPR™ Resistivity Pressure While Drilling Sensor

APS’s Pressure While Drilling (PWD) sensor for WPR™ measures annular and drill pipe pressures in WPR tools. Captured data may be transmitted in real time via APS’s SureShot™ MWD/LWD system, or stored in downhole memory for later download and analysis. Real-time data or pressure alarms may be transmitted via SureShot MWD.

Applications

Managing downhole pressures

Maintaining formation and borehole integrity

Managing hydraulics programs

Supporting early detection programs

Features & Benefits

  • Measurement and real-time monitoring of hydrostatic and dynamic circulating fluid pressures for balanced, managed pressure drilling (MPD) and underbalanced drilling (UBD).

  • Real-time annular and bore pressure measurements help assess the optimum pressures required within narrow fracture and pore pressure windows.

  • Real-time determination of equivalent circulating density (ECD) for hole cleaning, swab and surge pressures for borehole stability and BHA pressure loss.

  • Timely annular, bore and differential pressure readings facilitate early detection of fluid influx and lost circulation.

Design

  • For use with 4.75, 6.75 and 8.0 in. (121, 172 and 204 mm) WPR tools.
