Patent ID: 8126647

Claim:
A computer implemented method of analyzing characteristics of a subterranean formation comprising: applying, via a computer processor, a wavelet transform to measured data or to derived data obtained from the measured data, or to a portion thereof, the measured data obtained by measuring at least one physical property at each of a plurality of positions in a borehole that penetrates a region of the subterranean formation; selecting one or more scales for analyzing wavelet coefficients at each scale; performing a segmentation of the measured or derived data; calculating, via a computer processor, a distribution of wavelet coefficients for each scale, for one or more spatial directions of wavelet transform application, for the wavelet transform of the measured or derived data and for each segment that belongs to the portion on which the wavelet transform has been calculated; and for each segment, analyzing a distribution of the measured or derived data and the distribution of the wavelet coefficients for each scale in terms of their overlap with corresponding distributions of training samples to produce a geological interpretation of the subterranean formation.
