RGM-35A Ruggedised Gamma Module

The RGM-35A is a new generation MWD Gamma sensor module designed for the most severe vibrations and well conditions. The unique ‘oil-filled’ detector design provides shock and vibration attenuation like no other module in the market. The unit provides a ‘standard’ pulse output for compatibility with most MWD toolstrings and a unique interface and software, allowing in-house workshop test and calibration.

In addition to the ‘oil damping’, elimination of elastomer optical coupling and the need for an HV transformer translates to enhanced reliability in both high temperature and high vibration wells.

The RGM-35A module is qualified and tested under the extended range conditions, up to 50G rms vibration and 2000G shock.
