Abstract

Borehole nuclear magnetic resonance (NMR) measurements may be used to estimate permeability at several depth intervals in the saturated zone. The empirical Schlumberger-Doll Research (SDR) equation utilizes NMR-derived porosity and an average NMR relaxation time (representative of surface-area-to-volume ratio) to estimate permeability (kSDR) using three fitting parameters. While it would be possible to optimize the fitting parameters for each depth, it is more useful to have SDR equation parameter values that are valid for the entire length of a borehole or for a study site.
