Abstract
In accordance with the present invention, permeability estimates of a carbonate sample based on spin echo diffusion characteristics of the hydrogen nuclei of interstitial fluids within the pore space of such sample, can be swiftly and accurately achieved using a computer-controlled, portable NMR instrument. Result: Even though the instrument is placed at field sites away from the usual processing center, quick analysis of such samples as during the drilling of a well, still results.
