Radioactive Logging Parameters For Common Minerals
1979
This paper presents a list of about seventy minerals encountered in sedimentary formations together with their associated radioactive logging parameters. A procedure to calculate the radioactive parameters is given, and exact details are furnished for all logs but the neutron, which requires extensive and complex computation. It is significant that without considering rare elements such as boron, the computed neutron porosities assuming a thermal detecting device are consistently higher in shales, micas and zeolites than with an epithermal detecting device. This confirms our experience in the field. It is hoped that this compilation will serve as a qualititative aid in gauging the effect of most common minerals on the usual radioactive logging devices.
