oa An Overview of Reservoir Quality in Producing Cretaceous Strata of the Middle East

A compilation of average porosity and permeability data<br>for Cretaceous petroleum reservoirs of the Middle East<br>reveals important differences between the two main<br>tectonic provinces present in this region. The Arabian<br>Platform tectonic province is characterized by strong<br>inverse correlation of average porosity with present<br>depth in both carbonates and sandstones, whereas the<br>Zagros Fold Belt, containing almost exclusively<br>carbonate reservoirs, has distinctly lower porosity overall<br>and no porosity-depth correlation.
