摘要
A method of generating a data log includes receiving formation response signals with a nuclear magnetic resonance (NMR) tool. The method further includes processing the formation response signals to obtain a T1 distribution of nuclei of a mixture in the formation and performing a blind source separation (BSS) independent component analysis (ICA) on the T1 distribution. The method further includes obtaining mixing data, comprising ratios of components of the mixture, from the BSS ICA and generating a data log comprising the mixing data.
