Method and system for determining physical properties of rocky formations

Abstract

Method for determining physical properties of rocky formations, comprising: training a first artificial intelligence system (AI) on a first training dataset (TR). Said first training dataset (TR) comprises independent variables (V), associated with one or more rocky formations, comprising at least one of X-ray fluorescence (XRF) measurements, X-ray diffraction (XRD) measurements, and gamma-ray measurements. The independent variables (V) further comprise one or more drilling parameters. Said first training dataset (TR) comprises one or more dependent variables (V), comprising one or more physical properties of said one or more rocky formations. Said first training dataset (TR) is obtained from one or more training wells. Said method further comprises: determining operating data (OP), associated with a drilling of an operating well and comprising values of XRF and/or XRD measurements and values of said one or more drilling parameters (DP); executing a processing operation, wherein values of one or more of said one or more physical properties (PP) of a rocky formation crossed by said operating well are computed on the basis of said operating data (OP) by means of at least said first artificial intelligence system (AI).
