Patent No. 100 34 810

Measuring probe for borehole geophysical measurement of density according to the gamma-gamma backscatter principle

This is a patent for a gamma-gamma density probe that records the density, e.g. of the annulus filling of a groundwater monitoring well, in a rotationally symmetrical manner.
This type of probe is also commonly referred to as a "Rotating gamma-gamma density log" (RGG.D).

Patent No. 10 2004 024 237

Measuring probe for borehole geophysical measurement of density according to the gamma-gamma backscatter principle  

This is a patent for a gamma-gamma density probe which, due to the arrangement of detector and source transverse to the borehole axis, is particularly suitable for measurements in large boreholes and reacts significantly less sensitively to calibre eruptions than conventional probes.
