Abstract

The Sunniland Trend (Trend) in south Florida is an arcuate trend about 235 kilometers long by 30 kilometers wide that has supported oil production from the Sunniland Formation for over 60 years. The individual oil fields within the Trend have average porosities that range 15–18%, and have the potential to serve as carbon dioxide (CO2) sequestration reservoirs due to their high porosity and proven ability to trap hydrocarbons for millennia. In addition, the non-oil-bearing porous intervals of the Sunniland Formation along the Trend have relatively high porosities as well, with an average porosity range of 10–20%. All of the porous intervals in the Sunniland Formation within the extent of the Trend, including the oil-bearing intervals, have the potential to store ∼1.2 billion tons of CO2, which could potentially support CO2 sequestration for multiple large-scale power plants in the southeastern United States for their entire 40-year lifespan. The Sunniland Formation is an example of the large CO2 storage capacities that are potentially available in depleted oil and gas basins if all porous units, including those which are non-oil bearing, are considered for storage.
