Virtual permeametry on microtomographic images

We show that accurate numerical micropermeametry measurements can be performed on three-dimensional (3D) digitized images of sedimentary rock. The sample size can be very small, making it possible to predict properties from core material not suited for laboratory testing (e.g., drill cuttings, sidewall core and damaged core plugs). Simulation of fluid permeability on microtomographic images of Fontainebleau sandstone on sample sizes of less than I mm(3) are in good agreement with experimental measurements over a wide range of porosities.
