corner is not reached by any of the flow lines in the
“xx” direction because the fault are completely
interconnected in map view (Fig. 11 c).
According to our preliminary results, we believe
that this semi-automated process of lineament analysis,
followed by the use of power law distributions
constitute a valid approach to improve the
understanding of the bulk permeability distribution in
deformed porous carbonate reservoirs.
Despite the promising result obtained during this
preliminary study, some points of our model can be
improved to solve relevant issues. As future work, we
plan to carry out a systematic measurements of the
permeability of both pristine and deformed rock at
Favignana. The permeability values obtained by means
of a portable mini-permeameter will replace the
literature data used for this model. Moreover we will
test our modeling approach against a deterministic one,
based on real maps of the studied outcrop. This
comparison will allow us to establish the degree of
confidence of the workflow presented in this paper.
Acknowledgments: AC thanks his former
employer, Midland Valley Exploration Ltd., for
allowing him to use MOVETM for this study. During the
modeling, AC benefitted of fruitful discussions with G.
Johnson and R. Shackleton. The comments and
suggestions provided by A. Aydin sensitively improved
both quality and legibility of this paper.
