ABSTRACT

Geophysical length scales derived from complex resistivity (CR) and nuclear magnetic resonance (NMR) measurements offer promise for the non-invasive estimation of permeability. Petrophysical relationships linking NMR length-scales to permeability have been used in both sandstone and mudstone formations. In contrast, petrophysical relations linking CR length-scales to permeability have been limited to sandstones and unconsolidated sediments. The purpose of our study was to evaluate the predictive capability of CR-based permeability relations when applied to mudstones and to compare the predictions against those determined from NMR models.
