Description

The QL40-SGR probe measures the amount of gamma radiation occurring naturally within the formations crossed by a borehole and counts the number of gamma emissions associated with each energy level. Gamma rays are produced mainly by isotopes of potassium, thorium, and uranium and their decay products. The spectral gamma ray log is widely used in the mining and environmental industries for the identification of lithology, correlation between boreholes, and clay content analyses.

This tool is stackable within the Quick Link (QL) product line or it can be run as a standalone tool. The QL40-SGR operates on any standard wireline (single, 4 or 7 conductor, coax) and in any borehole environment.

Applications

  • Mineral Detection
