Statistics

We document the formation and evolution
of the damage zone associated with strike-slip faults in the Jurassic Aztec
Sandstone of the
The statistical properties of the fault
networks are determined through scanline surveys in
which we distinguish between the different structural elements and determine
the characteristics of each element. There is a systematic evolution in the
statistical properties of damage zones with fault growth attributed to the
progressive saturation of fault networks. Well-developed fault networks have multifractal properties with important consequences on the
forecasting of frequency and spacing characteristics of faults from limited
data sets. The conceptual model proposed here together with the statistical
data may be used as predictive tools to better estimate the geometrical and
statistical properties of damage zones associated with large faults with
resolvable slip magnitude detectable in the subsurface seismic data, with
important consequences for fluid flow.
