Product Description


The Gamma-ray tool measures gamma radiation from the formation surrounding the wellbore or for particular Condition. The detector comprises a 4in NaI scintillation crystal, photomultiplier and 1.6kV 

high voltage power supply. All models are compact, rugged and combine excellent sensitivity 

with high resolution for cased hole production logging condition. Tools can be combined for 

tracer work and, with the addition of a gamma source, used for gravel pack investigations.
