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.
