Gamma ray sensors measure the natural radioactive emissions from isotopes of potassium, uranium, and thorium contained in, or absorbed into the mineral components of sub-surface rocks. Each formation has a unique signature which provides drilling personnel an indication of lithology useful for confirming formation characteristics and geosteering.
The gamma ray sensor is composed of a scintillation crystal and a photo-multiplier which are sensitive components to place in the severe conditions encountered downhole. To address this inherent susceptibility, the FUSION GR sensor is housed in a proprietary suspension system that dampens the shock and vibration effects imposed on the crystal. Our innovation has significantly improved the reliability of our gamma tool and has reduced sensor failures.
Features
- Proprietary suspension system
- Higher shock tolerances
- Extended and focused GR modes
Applications
- Any project where operators seek an inexpensive and reliable solution for determining formation tops and boundaries
- Any horizontal wellbore where geosteering is required to track formation
Benefits
- Longer mean time between failures (MTBF) for GR sensor
- Real-time lithology data to surface
