Abstract

Porosity and density information were taken from five well logs scattered in East Baghdad oil field. New empirical equations (porosity-depth, density-depth) were established for all the geological formations within the Tanuma-Ahmadi interval. The correlation coefficient (R) of these equations derived for each formation ranged from 0.04 to 0.61 which was attributed to variable lithological effects.

The depth information for (126) velocity analysis sites covering the field were used to apply those new equations.

After the new empirical equations were applied on the whole field, porosity and density contour maps for the period (Tanuma-Ahmadi) were produced. The locations of high porosity zones were  identified and related to the compaction and petroleum distribution in the field.
