Product Description


The rugged gamma ray tool is used to measure natural gamma ray radiation generated from the downhole formation. Based on the inherent intensity of a known geological mineral deposit, the tool measuring depth can be determined. The rugged gamma ray tool differs from a conventional one in that it incorporates special anti-shock means in its electric connectors, electronics and sensors, enabling it to be logged with a perforator or a coring tool so that perforating or coring can be performed in a single run after the depth has been determined.



Mono-conductor cable transmission;
Pulsed signal, compatible with any surface logging system;
Rugged design so as to complete depth correction and perforation in one run;
Relay switching control to prevent wrong firing during logging;
Compatible with a rugged analog CCL.
