Potential for Carbon Dioxide Sequestration in the Lower Cretaceous Sunniland Formation Within the Sunniland Trend of the South Florida Basin, US

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

Baseline study and risk analysis of landfill leachate - Current state-of-the-science of computer aided approaches

For the successful completion of a risk analysis process, its foundation (i.e. a baseline study) has to be well established. For this purpose, a baseline study needs to be more integrated than ever, particularly when environmental legislation is increasingly becoming stringent and integrated. This research investigates and concludes that no clear evidence of computer models for baseline study has been found in a whole-system and integrated format, which risk assessors could readily and effectively use to underpin risk analyses holistically and yet specifically for landfill leachate. This is established on the basis of investigation of software packages that are particularly closely related to landfills. Holistic baseline study is also defined along with its implications and in the context of risk assessment of landfill leachate. The study also indicates a number of factors and features that need to be added to baseline study in order to render it more integrated thereby enhancing risk analyses for landfill leachate
