Title: A METHOD AND SYSTEM FOR VALIDATING LOGGING DATA FOR A MINERAL SAMPLE
Abstract:
Disclosed is a method for validating logging data for a mineral sample which has been obtained from a region of interest. The method comprises obtaining logging data associated with a composition of the mineral sample, the logging data including one or more estimated material types present in the mineral sample. Compositional assay data indicative of an actual composition of the mineral sample or another mineral sample provided from the region of interest, is obtained. An estimated composition of the mineral sample is then determined based on the estimated material types. The estimated composition is then compared with the compositional assay data, and a data validation controller is used to provide adjusted logging data based on: the comparison of the estimated composition with the compositional assay data; and stored validation criteria which defines allowable modifications to the estimated material types based on physical properties associated with the material types.
