Bench Tree’s LWD gamma module is a ruggedized, high-efficiency, scintillation-type detector assembly that seamlessly integrates with your MWD system to provide real-time formation gamma ray information. The logs allow you to correlate with open-hole logs, geosteer and identify low- and high-radiation lithologies.
Clients using the Bench Tree DPU2 downhole processing unit, with the feature package, can configure their MWD system to transmit additional gamma data while in rotating mode. They can also download high-resolution gamma data, which is stored in memory, at the surface. Advanced drill collar and environmental correction software is available, as is housing and hardware to package the unit as a discrete MWD probe module.
The LWD gamma module can be integrated with Bench Tree’s m+ Pulser near the bottom of the MWD string so gamma readings are closer to the drill bit. The API calibration factor for each LWD gamma module is determined when Bench Tree’s compatible gamma calibrator and software system are used to verify the sensitivity of each gamma probe as it correlates to API test pits.
