ADR™ Azimuthal Deep Resistivity Sensor

Optimize wellbore placement, maximize production and extend field life.

The ADR™ Azimuthal Deep Resistivity sensor comes together with the StrataSteer® 3D geosteering service to provide a fully compensated, multiple-depth resistivity measurement, petrophysical evaluation and stratigraphic navigation solution in one package.


ADR Sensor Benefits

  • Patented design acquires measurements in 32 discrete directions and 14 different depths of investigation to determine distance and direction to multiple bed boundaries
  • Deeper readings improve reaction time, allowing for increased drilling speed with less risk of drillout
  • Fully compensated petrophysical-quality resistivity measurements and deep reading geosteering measurements combined in one tool to minimize BHA length
  • Azimuthal readings provide for derivation of anisotropy values (Rh and Rv) and dip

The ADR sensor is the first of the new generation of logging-while-drilling sensors from Sperry.

The New Generation Delivers:

  • Deeper reading, higher resolution LWD sensors
  • Faster telemetry - through data compression, customizable data streams, and full IntelliServ® Network compatibility
  • Greater reliability - through component integration, meaning fewer electrical contact points at risk

The new generation sensors enable new understanding of formations not even possible with legacy systems.
