Production Gamma Ray

Production Gamma Ray

A depth correlation tool. The PGR measures the naturally occurring gamma ray radiation levels in the wellbore.

Applications

Gamma rays are emitted by naturally occurring isotopes that are associated with clays (K, Th, U). Rock with high content of clay (e.g. shale) will emit more gamma rays than rock with low clay content (e.g. sandstone or limestone).

KEY FEATURES

• Non-radioactive
• Depth correlation
• Lithology determination
• Identification of radioactive scale
• Tracer monitoring
• Combinable with other GE Ultrawire™ tools
• Memory or surface read-out operation
