... relaxation rate of the porous medium is thus affected by adsorption, which changes the surface relaxation rate and the relaxation rate of the fluid within the pore space. Electrostatic interactions drive nanoparticle adsorption onto pore walls. When silica porous media, which have negative surface charge...

... relaxation rate, however, must be significant compared to the bulk relaxation rate in order for wettability to noticeably affect the NMR response. We present results showing that the surface relaxation rate at lower wetting phase saturations is enhanced compared to that measured at higher saturations...

Paper Number: SPE-71700-MS
... Abstract We present NMR relaxation experiments of water and oil confined in a series of calibrated porous media and natural rocks of different wettability, at various temperatures and magnetic fields. The longitudinal 1/T 1 and transverse 1/T 2 relaxation rates are interpreted...

... sequence is unable to refocus the spins effectively when they are subject to such a time-varying internal field, and the observable signal decays. To characterize this diffusional loss mechanism, the proton T2 relaxation rate at 2 MHz in synthetic mono-disperse porous media was studied as a function...
