... and uncemented rock have wide and overlapping ranges of radar attributes ( Fig. 1 ). There is a correlation between the thickness and composition of the concretions with GPR responses, which produces clusters in the amplitude-frequency cross plots.

.... The cations used are Na + , Ca 2+ and Mg 2+ , which are readily found in formation brines. NMR spectra of clays exposed to brines tend to show distinct characteristics of both amplitude and mean relaxation. Analysis of the NMR spectra correlates the NMR response to clay-chemistry of the individual clays...
