摘要: We present diffusion-relaxation distribution functions measured on four rock cores that were prepared in a succession of different saturation states brine and crude oil. The measurements performed static gradient field at Larmor frequency 1.76 MHz. clearly separate the contributions from two fluid phases. results can be used to identify wetting non-wetting phase, infer properties phases, obtain additional information geometrical arrangement also observe effects due restricted diffusion susceptibility induced internal gradients.
