Calibrating NMR response to capillary pressure curves in fine grained lithologies: Pretty Hill Formation, Otway Basin
… by many factors such as magnetic susceptibility, surface relaxivity and aspect ratio. Therefore, using the NMR response to estimate capillary displacement pressures in iron-rich, fine grained rocks is not recommended. However, further studies in rocks of low magnetic suscepibility might yield more …

Permeability, Pore Body, and Pore Throat Size Distributions from 2D Image Analysis: Comparison with Results from 3D Imaging and Laboratory Measurements
… and pore throat size distributions, and specific surface area from 2D-images. Then compare those estimates of pore body and pore throat size distributions from thin section to those obtained from 3D imaging, Nuclear Magnetic Resonance (NMR), and Mercury Injected Capillary Pressure (MICP) …

Nuclear Spin Relaxation and Diffusion Studies of Adsorption and Dynamics at the Catalyst-Liquid Interface
… recently emerged as a novel tool for probing surface dynamics within such systems; herein, we detail the state-of-the-art of such measurements, and extend our current understanding of how such characteristics may be interpreted in terms of formal surface interaction phenomena. Initially, a …

Characterization of catalyst pellets using NMR and MRI: MRI, diffusion and relaxation measurements of liquid imbibed in alumina and titania extrudates
… in porous material are sensitive towards the surface to volume ratio of the pores, the liquid-solid adsorption strength and the presence of relaxation sinks (including paramagnetic species) at the pore surface. T<sub>2</sub> relaxation maps revealed significant heterogeneities. An increase in …
