Gama Ray Tool

The gamma ray tool (GRT) measures the natural gamma ray generated from the formation that surrounds the wellbore. The sensor comprises a 4" sodium iodide scintillator, a photomultiplier and a 1.6kV high voltage power supply. The models of GRT are compactly designed and offers good sensitivity and high resolution for use in cased-hole production logging operations. The Tool, combined with other tools, may be used for flow tracer work and, with the addition of a gamma source, for gravel pack investigations.

Application:

●    Lithological identification

●    Depth correction

●    Identification of radioactive scale

●    Tracer monitoring

●    Gravel pack monitoring (with an addition gamma source)

Benefits:

●    High speed data telemetry system

●    Combinable with high speed wireline telemetry cartridge (WTC)

●    Good vibration resistance performance
