Presentation Overview1) New Mexico sits astride a highnear surface heat flow trend thatstretches from Colorado south tothe Mexican border. 2) New Mexico is part of a broad
trend of states with deeper oiland gas wells that extends fromthe Gulf Coast NNW to Montana.
3) West Texas Permian Basingeothermal investigations suggestthat parts of New Mexico may alsohave geothermal power potentialfrom deeper oil and gas wells.
4) Trans-Pecos region of WestTexas has promise of geothermalpower as part of the Rio GrandeRift, stretching from the Big Bendof Texas through New Mexico andinto Colorado.5) Geothermal energy may have
the highest capacity factor of allthe renewable energy resourcesavailable for power generation.

Existing geothermal power generation has focused on western states where high heat flow exists
at or near the Earth’s surface.

New opportunity exists through the many oil and gas wells that have been drilled in the deeper sedimentary
basins that have encountered hot temperatures.

A major importance of geothermal power production is that it has a high capacity factor.
Thus geothermal impacts base load electrical demand.

Conclusions
New Mexico sits astride a high near surface heat flow trend that stretches from Colorado south to the Mexican border.
New Mexico is part of a broad trend of states with deeper oil and gas wells that extends from the Gulf Coast NNW to Montana.
West Texas Permian Basin geothermal investigations suggest that parts of New Mexico may also have geothermal power potential from deeper oil and gas wells.
Trans-Pecos region of West Texas has promise of geothermal power as part of the Rio Grande Rift, stretching from the Big Bend of Texas through New Mexico and into Colorado.
Geothermal energy may have the highest capacity factor of all the renewable energy resources available for power generation.
