Abstract
A method for quality control of gamma-gamma well logging data within a borehole for mineral exploration, including receiving, at a computing device, raw well logging data; identifying and formatting data sets from the raw well logging data; applying at least one quality control process to the formatted data sets, the at least one quality control process being selected from: a linear verification process comparing linearity of density data readings between a long and a short spaced sensor in a probe; a density range verification process comparing density readings at the probe with density ranges for the borehole lithology; a diameter comparison process comparing actual diameter of the borehole at a depth with density readings at the depth; and a residual verification process for verifying a proportionality between densities measured by the long spaced sensor and short spaced sensor; compiling the results and providing an output of the compiled results.
