Simultaneous Measurement of Rock Permeability and Effective Porosity using Laser-Polarized Noble Gas NMR
arXiv:cond-mat/0312543 · doi:10.1103/PhysRevE.70.026312
Abstract
We report simultaneous measurements of the permeability and effective porosity of oil-reservoir rock cores using one-dimensional NMR imaging of the penetrating flow of laser-polarized xenon gas. The permeability result agrees well with industry standard techniques, whereas effective porosity is not easily determined by other methods. This novel NMR technique may have applications to the characterization of fluid flow in a wide variety of porous and granular media.
