Density Gamma Probe

The Density Gamma probe (sometimes referred to as a Trisonde) offers a convenient, low cost alternative to the standard Formation Density probe whenever borehole diameter is restricted and qualitative density measurements are acceptable.

One common application is in logging through drill pipe when unstable borehole conditions prevent use of unprotected nuclear probes. The probe is unfocussed and indicates the average density of material surrounding the borehole.

Principle of Measurement: 

The probe contains a detachable 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 count-rates provide an indication of formation bulk density
