The GRT-5 Gamma Ray Tool is a standard scintillation detector type production gamma ray tool housed within an in line GSR compatible body. The GRT-5 is run in “digital” gamma mode. In this mode the GRT-5 is connected immediately below the STAS. The STAS provides the gamma power and reads the gamma count via pin 3. The STAS transmits the gamma information to the surface digitally with all other status information in Geochain Slim’s Monitor mode.
- Surface Control –The Geochain System Panel (GSP) with an inbuilt Gamma Control Module (GCM) is required for all gamma tool systems.
