Hydrocarbon Potential of Offshore South Florida Basin
Barry M. Faulkner, Albert V. Applegate
The results of an extensive, detailed geologic and geophysical evaluation of the offshore South Florida basin show this area to have considerable hydrocarbon exploration potential. Geophysical mapping on six key horizons identified numerous structural closures at Dollar Bay through Bone Island mapping levels. Geologic evaluation indicated at least four viable potential reservoir horizons, including the Sunniland formation--the main producing unit onshore in what is called the "Sunniland trend." Mature, organic rich carbonate source rocks are found in several stratigraphic intervals throughout the basin, and extensively developed seals consisting of micritic limestones and anhydrites are also common in the stratigraphic section. All the critical factors for hydrocarbon acc mulation--source, reservoir, trap, and seal--appear to be present in the offshore Pulley ridge area of the South Florida basin.
Using high-resolution seismic data, additional evaluations of land areas already identified could discover significant hydrocarbon reserves in this shallow-water sparsely drilled, carbonate basin oil play.
