HOW the FRACTAL DIMENSION of a POROUS
MEDIUM EFFECTS the RESPONSES
of STANDARD NUCLEAR LOGGING TOOLS



Program LVPM has been modified to accept fractal dimension
INPUT information about porous media. This information
could come from laboratory measurements on soil/rock samples
or from log analyses.
Previous versions of LVPM used a single pore
size to describe earth formations.


The main objective is to provide even more realistic and accurate
reservoir analyses from nuclear logs both by accounting for
fractal properties during fundamental tool calibrations and for
developing environmental corrections for fractal properties
during logging and post-processing.


The seminal papers of Michel Rieu and Garrison Sposito,
"Fractal Fragmentation, Soil Porosity, and Soil Water Properties:
I. Theory and II. Applications," SOIL SCI. AM. J., SEP-OCT,
(1991), pp. 1231-1238 and 1239-1244 have been very widely read
but they can be difficult to follow. A non-printable pdf of
these very important and influential papers is included just
below. A more extensive list of references is also provided at
the end of this section.

Doctor Neutron's activities with fractals have been guided by
the work of Allen G. Hunt. See his book "Percolation Theory
for Flow in Porous Media", Springer, 2005, ISBN: 3-540-26110-9.
Pages 44 - 49 provide an exceptionally clear explanation of the
partial volume expansion of Rieu and Sposito and its extension to
continuous pore size distributions.

For Doctor Neutron, clearly the most important and useful result
from these references is exemplified by Hunt's equation (2.16):
