1. Core data: 15 wells, up to 600 ft of core, are available. 6 main lithofacies are recognized and classified based on core description and thin sections.

2. Log data: about 200 wells have digital logs, including GR, Resistivity log, density, porosity (neutron & density porosity) and PE. Several wells have stratigraphic dipmeter logs.

3. Petrophysical data: 10 wells have measured porosity and permeability data. Mini-perm have been measured within the ooid shoal interval in two wells.
