Abstract
Recent research in carbonate provinces has shown that micritized oolite grainstones may develop a bimodal pore system containing both micro and mega porosities. However, the extent and frequency of bimodal pore system occurrence has not yet been determined. Bimodal pore systems in oolites have been reported in the Silurian Interlake, Jurassic Smackover, and Cretaceous Sligo and Rodessa formations. Recognition of the presence of microporosity has significant implications for accurate assessment of the hydrocarbon potential of oolitic carbonate reservoirs. These reservoirs require specialized petrophysical log analysis because of their unique characteristics
