Exploration and Resource Definition
• Expanded GRED (Geothermal Resource Exploration and Definition)
• Cost-Shared Drilling– Slim-hole– Reservoir confirmation– New Exploration
• Fracture Targeting– Geochemical Techniques– Geophysical Techniques

Drilling Technology
• Reactivate GDO (Geothermal Drilling Organization)
• Continue Lost Circulation Control Research
• Develop Suite of Cementing Materials and Techniques
• Basic Research– Bit Technology– Logging while drilling

Reservoir Confirmation, Characterization and Management
• Integration of Basic Geophysical, Geochemical Data into more Robust Reservoir Models
• Incorporate Fluid Chemistry and non-conservative tracers into numerical modeling techniques
• Support publication of case studies with demonstrated efficacy of Reservoir Modeling

Enhanced Geothermal Systems
• Expand Funding Level– Potential for near-term deployment– Requirement to test multiple concepts
• Near-term focus should be on EGS coupled with producing hydrothermal

Hardware Development
• Downhole Pump Temperature limitations
• Materials Demonstration– Anti-scalant Coatings– Corrosion Protection
• Combination Logging Tools– PTS-Density Tool
• Advanced H2S abatement

Distributed Power and Non-Electric Uses
• Off-grid Village Power Generation– 50 kW to 5 MW
• Mineral Recovery– Zinc, Manganese– Silica– Lithium, Potassium, Cesium, Rubidium
• Agribusiness and space heat, industrial process heat

Information Dissemination, Education and Outreach
• Maintain funding for Scientific Meetings and Publications
• Geothermal is a viable renewable energy source for the future– Indigenous– Energy security– Low Emissions
• Educate Public, Policy Makers

US and Mexico Co-operative Work
• Presented to and Discussed with Mexico Secretary of Energy Martens– Geothermal Reservoir Identification and
Management– Geothermal Deployment Strategy– Integrated Uses of Geothermal Resources
• Secretary Martens intends to discuss with US Secretary of Energy Abraham

Barriers to Short Term Deployment
• Lack of Power Sales Contracts
• Capital Front-End Loading of Geothermal Projects
• Limited Inventory of Proven Resources
• Attracting Capital Investment
