ABSTRACT: This
study aims to have a single coefficient resulting from the integration of all
the reservoir parameters through which a decision can be taken to determine the
best quality places in the reservoir. The conventional well logging data in
nine wells were used to determine the reservoir parameters in the study area.
Seven different parameters were calculated, five of them were directly
proportional to the quality of the reservoir, while the remaining two
parameters which represent shale volume and water saturation were inversely proportional
to the reservoir quality. The index of each parameter was calculated. A new
value was created from the integration of the seven different parameter indexes
called the weighted index for the reservoir quality. The reservoir quality
values were sliced in the three dimensions depending on the effect of all
reservoir parameters and not on any single parameter. It is clear from the
results of this study that horizontal and vertical slicing, as well as cut-off
values, illustrates that the middle and upper parts are the best places for the
reservoir to explore hydrocarbons, where the values of the weighted index of the reservoir quality range from 0.65 to 0.9. Meanwhile, the quality
of the reservoir decreases in its lower parts.
