T
he quality and assessment of a reservoir can be documented
in details by the application of seismo electric bio availability.
This research aims to calculate fractal dimension from the
relationship among seismo electric bio availability, maximum
seismo electric bio availability and wetting phase saturation
and to approve it by the fractal dimension derived from the
relationship among capillary pressure and wetting phase
saturation. In this research, porosity was measured on real
collected sandstone samples and permeability was calculated
theoretically from capillary pressure profile measured by
mercury intrusion contaminating the pores of sandstone
samples in consideration. Two equations for calculating
the fractal dimensions have been employed. The first one
describes the functional relationship between wetting phase
saturation, seismo electric bio availability, maximum seismo
electric bio availability and fractal dimension. The second
equation implies to the wetting phase saturation as a function
of capillary pressure and the fractal dimension. Two procedures
for obtaining the fractal dimension have been utilized. The
first procedure was done by plotting the logarithm of the
ratio between seismo electric bio availability and maximum
seismo electric bio availability versus logarithm wetting phase
saturation. The slope of the first procedure = 3- Df (fractal
dimension). The second procedure for obtaining the fractal
dimensionwas determinedby plotting the logarithmof capillary
pressure versus the logarithm of wetting phase saturation.
The slope of the second procedure = Df -3. On the basis of the
obtained results of the fabricated stratigraphic column and the
attained values of the fractal dimension, the sandstones of
the Shajara reservoirs of the Shajara Formation were divided
here into three units. The obtained units from bottom to top
are: Lower, Middle and Upper Shajara seismo electric bio
availability Fractal Dimension Units. It was found that fractal
dimension increases with increasing grain size and permeability.
