The three order of magnitude variation in the proton NMR longitudinal relaxation time T//1 of water adsorbed on silica surfaces versus that of bulk water makes proton NMR studies of porous materials powerful tools to study the effects of adsorption. Recent theory permits the utilization of the different response to obtain pore space surface to volume distribution functions by inverting the decay of the z component of magnetization of fully saturated porous rocks; information can likewise be obtained on the fluid distribution at partially saturated conditions. A computer program has been developed to invert the NMR relaxation curves for the //V OVER BAR **S distribution function, assuming an isolated pore regime, the ramifications of which are examined.
