A Comparison of Pore Size Distributions Derived by NMR and X-ray-CT Techniques

Arns, Christoph


High resolution micro-X-ray-CT data is used as a "gold standard" to define the morphology of a number of sandstones as well as a carbonate rock. From these micro-CT images the NMR responses to surface relaxation and restricted diffusion in the internal magnetic field are calculated numerically. The NMR response is decomposed into a distribution of relaxation times by an inverse Laplace transformation. By interpreting the relaxation time distributions in terms of relaxation and diffusion modes...[Show more]
