Fluid flow in porous media: NMR imaging and numerical simulationby Submitted to the Department of Earth, Atmospheric, and Planetary Sciences on May 10, 1999 in partial fulfillment of the requirements for the degree of Master of Science ABSTRACT We use nuclear magnetic resonance (NMR) imaging to obtain a three-dimensional
image of the pore structure in a limestone core, 4.5 mm in diameter and 10 mm
in length, with a resolution of 40 mm. This image is converted into boundary conditions
for simulation of fluid flow through the rock using the lattice gas method. The
computed permeability is several orders of magnitude lower than the laboratory
measured permeability, most likely a result of the image resolution being too
coarse to resolve the smaller pore throats, which are believed to be significant
for flow in this sample. Return to Theses Return to ERL Home Updated: June, 1999
