Sperry Drilling Services, a brand of Halliburton’s Drilling and Evaluation Division, used its new InSite ADR™ Azimuthal Deep Resistivity Sensor to assist Norsk Hydro ASA in the optimization of well placement on its Oseberg Field development project in the North Sea.
Hydro’s challenge was to drill in a thin, heterogeneous reservoir setting. The InSite ADR sensor helped Hydro to steer the well through the most productive part of the reservoir while maintaining a desired distance away from the adjacent formations, thus ensuring maximum production from the well. Sperry’s geosteering specialists collaborated with Hydro’s drilling and geology & geophysics (G&G) team to interpret sensor data and to make recommendations for real-time course corrections.
InSite ADR Sensor Benefits
Patented design takes 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 InSite ADR sensor is the first of the new InSite Generation of logging-while-drilling sensors from Sperry.
The InSite 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 InSite Generation enables a thorough understanding of formations not possible with legacy systems.
