Project Title Demonstrating the Commercial Feasibility of Geopressured-Geothermal Power Development at Sweet Lake Field Cameron Parish, Louisiana
Project Type / Topic 1 Recovery Act: Geothermal Technologies Program
Project Type / Topic 2 Geothermal Energy Production from Low Temperature Resources, Coproduced Fluids from Oil and Gas Wells, and Geopressured Resources
Project Type / Topic 3 Geopressured Resources
Project Description Within the Sweet Lake Oil and Gas Field, the existence of a geopressured-geothermal system was confirmed in the 1980s as part of the DOE’s Gulf Coast Geopressured-Geothermal Program. At the close of that program it was determined that the energy prices at the time could not support commercial production of the resource. Increased electricity prices and technological advancements over the last two decades, combined with the current national support for developing clean, renewable energy and job creation it would entail, provide the opportunity to develop thousands of megawatts of geopressured-geothermal power in the South Eastern United States.

Awardee Cost Share $10,202,879.00
Total Project Cost $15,202,879.00

Principal Investigator(s) Louisiana Tank, Inc.

Targets / Milestones - Utilize a well design specific to the conditions anticipated for a geopressured geothermal reservoir at the site, drilling and testing of a production well to a depth of 16,000 feet (without any matching funds from the DOE) prior to beginning the cost-shared project.

- Develop conceptual and numerical models of the reservoir and quantify the reservoir characteristics, using log, core, and flow test data from the well.
- Based on the above steps, designing the most appropriate surface technology and power plant design to optimize production of electricity from heat, kinetic energy and dissolved methane gas in the brine.
- Drill an injection well, conduct a long-term test of the production well, construct all surface facilities and power plants, and start power generation.
- Assess the technical and economic aspects of performance of the constructed system, and direct and indirect job creation from the project.
