Invasion Percolation on Correlated and Elongated Lattices: Implications for the Interpretation of Residual Saturations in Rock Cores
The invasion percolation model is used to investigate the effect of correlated heterogeneity on capillary dominated displacements in porous media. The breakthrough and residual saturations are shown to be strongly influenced by the correlations. Correlated heterogeneity leads to lower residual saturations than those observed in random systems and the scatter commonly observed in laboratory core measurements of the residual saturations can be attributed to the presence of such heterogeneity at...[Show more]
