the Permo-Carboniferous Shajara Formation, Saudi Arabia

T
he quality and assessment of a reservoir can be
documented in detail by the application of seismo
radial grain velocity. This research aims to calculate fractal
dimension from the relationship among Seismo radial grain
velocity, maximum seismo radial grain velocity and wetting
phase saturation and to approve it by the fractal dimension
derived from the relationship among capillary pressure and
wetting phase saturation. Two equations for calculating
the fractal dimensions have been employed. The first one
describes the functional relationship between wetting
phase saturation, seismo radial grain velocity, maximum
seismo radial grain velocity 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 radial grain velocity
and maximum Seismo radial grain velocity versus logarithm
wetting phase saturation. The slope of the first procedure = 3-
Df (fractal dimension). The second procedure for obtaining the
fractal dimension was determined by plotting the logarithm
of 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.
