Abstract:
We show that accurate numerical micropemleametry
measurements can be perfomled 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 pemleability on
microtomographic images of Fontainebleau sandstone on
sample sizes of less than 1 mm3 are in good agreement
with experimental measurements over a wide range of
porosities.
