Developing Experimental Petrophysical Relationships for Geological Stratigraphic Succession (Hartha- Fatha Formations) in the East Baghdad Oil Field

The present study deals with experimental mathematical equations
that link density and porosity with depth. After obtaining the
density and porosity information from five well logs scattered in
the East Baghdad oil field, new empirical equations (porositydepth, density-depth) were produced for all the geological
formations within the period between the Fatha and Hartha
Formations. The correlation coefficient (R) of these equations
derived for each formation ranged from 0.06 to 0.87, which was
attributed to variable lithology effects. The depth information of
(126) velocity analyses situated at the seismic lines grid covering
the field had been used for applying the new equations. After the
new empirical equations were applied to the whole field, porosity
and density contour maps for the period (Fatha- Hartha) were
produced. The locations of high porosity zones were identified and
related to the compaction and petroleum distribution in the field.
