Nuclear magnetic resonance (NMR) is a powerful, noninvasive measurement method which can be used to obtain spatially resolved information about fluid distributions within media. In the present work, an approach for quantitatively analyzing magnetic r

This study develops a methodology for determining the absolute permeability distribution in a porous media sample using velocity data obtained from NMR imaging experiments. An objective function describing the discrepancy between observed and simulat

Two NMR velocity imaging methods based on the pulsed field gradient stimulated-echo technique are evaluated for the measurement of fluid flow in porous media. The spatial resolution and dynamic scale of velocity imaging experiments are chosen to repr

We use nuclear magnetic resonance (NMR) imaging to determine spatial distributions of properties used to describe flow in heterogeneous porous media. The methods are demonstrated on sandstone samples, which are characteristic of underground formation
