The Reservoir Potential of Miocene Carbonates Rocks in the Adana Basin, Southern Turkey

P132 The Reservoir Potential of Miocene Carbonates Rocks in the Adana Basin Southern Turkey A. Buyukutku* (Ankara University) SUMMARY This paper reports on the microfacies diagenesis and reservoir properties of the Lower-Middle Miocene Karaisal  Formation in the Adana Basin southern Turkey. The Karaisal  Formation reflects the continuous deposition of shallow-shelf carbonates. Karaisal  Formation carbonates are up to 500 m thick. The best reservoir conditions in the Karaisal  Formation occur in grain- supported facies such as Foraminiferal-Algal packstones. Secondary vuggy and moldic porosity which are common in the Foraminiferal/Algal Packstones resulted from micritic cement and the dissolution of skeletal grains during
