Density Gamma Probe

By: GeoLog Pty Ltd  04-Jul-2012
Keywords: Logging, Density

Principles of Measurement The probe contains a gamma source and two high-sensitivity scintillation gamma detectors. Gamma radiation from the source is backscattered by the formation (Compton effect) and reaches the two detectors where the relative count-rates provide a measure of formation bulk density. Features Long-spacing detector (LSD) for deep penetration and immunity from borehole effects. High-resolution detector (SSD) for accurate bed-boundary detection. Bed-resolution detector (BRD) for shallow penetration and borehole effects. Measurements Long-spacing density (LSD) High-resolution density (SSD) Bed Resolution density (BRD) Temperature Natural gamma
