399:, and the values that should be used in mathematical models for large scale predictions is a central topic of Gómez-Hernández's PhD dissertation, out of which a new methodology for the characterization of the spatial variability of permeability at various scales was developed. In this field, he was the first to demonstrate the difference between block values and effective values and show that block values depend on the block size and are generally non-local.

As a result of this paradigm shift from traditional inverse modeling to stochastic inverse modeling, Gómez-Hernández has focused on the development of new techniques that would improve the results of the self-calibrating method. A number of his more recent papers demonstrate the applicability of the
