Method and system for quality control in gamma-gamma data during mineral exploration

A method, at a computing device, for quality control of gamma-gamma well logging data within a borehole for mineral exploration, the method comprising:

• receiving, at the 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 spaced sensor and a short spaced sensor in a gamma-gamma well logging probe;
• a density range verification process comparing density readings at the gamma-gamma well logging 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 of the at least one quality control process;
• and
• providing an output of the compiled results.
