ABSTRACT:
A technique for measuring the density and a lithology-dependent factor, compensated for borehole effects, with a gamma ray logging source and one or more gamma ray detectors has been disclosed. Other borehole variables are also measured and used as quality indicators. The technique uses the spectral information from the detected gamma rays to calculate all of the unspecified variables relevant to the measurement. This technique also allows a lithology-dependent parameter based on the short-spaced detector to be compensated for borehole effects without contaminating the measurement with lesser-quality data from a detector spaced further from the source. Furthermore, it allows multiple measurements of a lithology-dependent factor made with multiple detectors to be compensated separately. The multiple compensated measurements can then be combined to form a quantity which indicates the quality of the measurement. This technique also allows the measurement of a compensated density whose vertical resolution is that of the short-spaced detector.
