title: Susceptibility contrast and transverse relaxation in porous media: simulations and experiments.
abstract: A numerical simulation of spin diffusion in inhomogeneous magnetic fields due to susceptibility contrast was developed to describe the transverse relaxation of fluids in porous media. The simulation results are in quantitative agreement with experimental measurements obtained on samples of simple geometry. They also confirm the interpretation of the 1H transverse relaxation observed in natural rocks either hydrophilic or hydrophobic for several deuterium oxide/oil saturations, based on the traditional description of water and oil arrangement.
