Title:
NMR ANAYLYSIS SYSTEM AND METHOD FOR POROUS MEDIA
Document Type and Number:
WIPO Patent Application WO/2017/028161
Kind Code:
A1
Abstract:
Nuclear magnetic resonance (NMR) simulations of a porous medium are provided based on physical data such as CT images. A method of evaluating the surface relaxation of the porous medium based on random-walk NMR simulations includes a novel algorithm to derive the absorption probabilities of the random walkers, and algorithms that can evaluate more accurately the surface area and reduce the voxel discretization effect. The method can be applied to conventional porous media as well as unconventional porous media such as reservoir rocks with high surface-to-volume ratios, for example tight sandstones or shale.
