  1. 2008 New Mexico Geothermal Energy Working Group MeetingPerma Tools An energy company reaching new deep resources in fossil energy and geothermal power production Randy Normann, CTO

  2. Heat Of The Earth • Approximately 99% of the earth is >1000C (1800F) • Approximately 99.9% of the earth is > 100C (212F) the boiling point of water • Information from the German Energy Agency

  3. Expected US Temperatures at 6kMDOE & Dr. Dave Blackwell, SMU

  4. NM Temperatures at 6km

  5. Temperature (°C) 10 20 30 40 50 0 Water table 100 200 Sandia computer tool 300 DTS tool 400 m ) 500 ( h t p e D 600 700 SMU electric-line tool 800 900 SMU computer tool 1000 0 15 30 45 60 75 Gradient (°C/km) Increasing Temperatures as a Function of Depth • Earth is renewable energy • The Earth temperature gradient is between 17-30C/Km • Even the Kansas well temperature profile to the left shows increasing temperatures as a function of depth. From: “how Hot Is It” , Ken W. Wisian et al, GRC trans. V20,September/Oct 1996

  6. The Earth is Renewable Energy • Well temp gradients are range up to 60C/km! • Natural occurring K40 (potassium) is richer in some formations than others • NM has both uranium and potassium (potash) From: “how Hot Is It” , Ken W. Wisian et al, GRC trans. V20,September/Oct 1996

  7. EGS: Enhance Geothermal Resources • For New Mexico, EGS could mean: • Converting deep oil and gas wells to geothermal power production • Small binary power plants • Heat harvesting of hot co-produced fluids • Creating man made geothermal reservoirs • Hot dry rock projects • Potentially large power plants • Working fluids not limited to water but could be CO2 or other fluids

  8. EGR: Engineered Geothermal Reservoir Well is drilled to desired temperature and rock type. Hydraulic pressure is used to fracture the rock.

  9. Fractures Can Reach 1000s of Feet Away From the Well

  10. Enclosed Geothermal System The fractured rock is used as an heat exchanger. This is the standard concept shown in EGS presentations.

  11. A More Realistic View Horizontal wells can reach up to 6 miles in length!! Horizontal wells in the hot formations can greatly increase the size of the reservoir.

  12. Shameless Ad First geothermal tool – designed at Sandia built New Mexico business.

  13. Conclusion • New Mexico has significant geothermal potential for EGS • Small power binary power plants • Large EGR power plants • Questions for the group • Has anyone looked at the potential heat generated in NM rock formations? • Has anyone considered using other fluids other than water for a hot dry rock heat exchanger for New Mexico EGS?
