Method and system for evaluation of gamma-gamma well logging data in mineral exploration

摘要

#$%^&*AU2015202367A120151119.pdf#####ABSTRACT A calibration site for a gamma-gamma well logging tool for use in mineral exploration, the calibration site having a column consisting of a plurality of blocks of known densities; and a borehole through the column configured to accept the gamma-gamma well logging tool. Further, a method for calibrating a gamma-gamma well logging tool at the calibration site, the method including lowering the gammagamma well logging tool into a column consisting of a plurality of blocks of different known densities and having a borehole therein to receive the gamma-gamma well logging tool; raising the gamma-gamma well logging tool at a set rate; capturing a radiation count at a sensor of the gamma-gamma well logging tool; converting the radiation count to a recorded density for a particular depth at a computing device; and comparing the recorded density at each position of the column with the known densities.
