Gamma Module

Reliable gamma performance in the harshest downhole environments.

Sigdrill's accurate and reliable resistivity tool

Consistent Gamma Data, Run After Run


The Sigdrill 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 Sigdrill 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.
