While transport theories that treat ‘homogeneous’ porous media are mathematically convenient, such homogeneity rarely, if ever, exists in the field. The heterogeneity of natural geological formations at a wide range of scales necessitates consideration of more sophisticated transport theories.

To make the problem tractable, the log conductivity fluctuation, ., about the mean log conductivity, 1nK., is assumed to have finite variance, σ.. Historically, perturbation schemes have involved the assumption that σ. <1. Here it is shown that . may

Yet in practice these parameters can be deduced from measurements only at selected locations where their values depend on the scale (support volume) and mode (instruments and procedure) of measurement. Quite often, the suppor
