AbstractThis study deals with empirical equations linking density and porosity with depth. The density and porosity information were taken from five well logs distributed in the East Baghdad oil field. New empirical equations (porosity - depth, density - depth) for two geological formations (Harta and Sa'di) within Hartha- Tannuma period were produced. The correlation coefficient (R) of these equations ranged from -0.37 to 0.68, which was attributed to variability in lithology and compaction. The depth data of (133) points suited at seismic lines grid scattered in the field were used for applying the new equations. After the new empirical equations that are applied on the whole field, porosity and density contour maps for the period (Hartha- Tannuma) and the two formations (Hartha and Sa'di) were plotted. The high porosity zones were identified, are related to the compaction and petroleum distribution in the field.
