Gamma-ray Tool 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.

Applications & Benefits:
 

• Lithology Identification
• Depth Correlation
• Identification of Radio Active Scale
• Tracer Monitoring
• Gravel Pack Monitoring (with addition of a gamma source)
• H2S resistant
