bench tree's accurate and reliable resistivity tool

Advanced Measurement. Extended Performance.


The Bench Tree Gamma Detector Module delivers reliable, accurate gamma measurements in high-temperature and high-shock drilling environments. Engineered for durability and long service life, the module operates consistently run after run, helping operators maintain confidence in formation evaluation and directional decisions.


Available in 175°C, 185°C, and 200°C configurations, the ruggedized design reduces temperature- and vibration-induced measurement errors while extending battery life downhole. Its compact chassis is designed as a drop-in replacement for standard MWD systems, enabling seamless integration and dependable performance in demanding wells.


By minimizing false gamma counts and eliminating measurement drift in high-temperature wells, the Bench Tree Gamma module improves reliability, reduces operational risk, and supports efficient drilling operations across a wide range of applications, including directional, multilateral, SAGD, geothermal, and other extreme drilling environments.
