Calibrating NMR response to capillary pressure curves in fine grained lithologies: Pretty Hill Formation, Otway Basin

This study aims to generate nuclear magnetic resonance (NMR)-derived down-hole pseudo capillary pressure curves in very fine grained lithologies in order to determine whether it is possible to estimate capillary displacement pressures and thereby sealing capacity. Study conclusions are that T2 response in high iron content rock is affected 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 significant correlations.
