The Geolink Gamma Sensor uses wireline standard measurement technology in a specially ruggedised assembly to provide an accurate gamma log while drilling.
Description
The Sondex Drilling Gamma Sensor utilises a scintillation counter (NaI Crystal) and a photomultiplier mounted within a specially designed package which provides protection against the high levels of shock and vibration encountered in the drilling environment. The sensor is mounted in the LWD string as part of the Modular Gamma Ray Assembly (MGRA), capable of transmitting real time formation gamma ray information to surface for correlation and geosteering purposes . It also stores high resolution data downhole for later download at surface. The MGRA is calibrated against the API standard so that the log can be compared directly with wireline gamma logs. Geolink Navigator surface software automatically corrects the signal for the attenuating effects of the drill collar and tool housing.
