Project Title Innovative Exploration Techniques for Geothermal Assessment at Jemez Pueblo, New Mexico
Project Type / Topic 1 Recovery Act: Geothermal Technologies Program
Project Type / Topic 2 Validation of Innovative Exploration Technologies
Project Description This collaborative project will perform the following tasks to fully define the nature and extent of the geothermal reservoir underlying the Jemez Reservation:

- Conduct 1-6,000-scale geologic mapping of 6 mi2 surrounding the Indian Springs area.
- Using the detailed geologic map, locate one N-S and two E-W seismic lines and run a seismic survey of 4 mi2; reduce and analyze seismic data using innovative high-resolution seismic migration imaging techniques developed by LANL, and integrate with 3-D audio-frequency MT/MT data acquired at the same area for fault and subsurface structure imaging and resource assessment.
- With the results of the tasks above, locate and drill two exploration wells up to 3000 feet deep to penetrate the deeper geothermal reservoir. At least three hundred feet of core will be collected from the target interval for each well.
- Conduct detailed well testing, including an innovative tracer test and a test of flowing electrical conductivity (FEC), to determine the fracture surface area, heat content and heat transfer, flow rates, and chemistry of the geothermal fluids encountered by the exploration wells.
- Write final report summarizing the nature and extent of the geothermal reservoir in the Indian Springs area, including the potential for commercial power generation and direct use applications.

Location of Project Jemez Pueblo, NM
About the Area In 1991 a well was drilled on the Jemez Reservation to explore Indian Springs hot springs. This well produced water of 136°F from a depth of 240 feet with a flow of 150 gallons per minute. The source of this geothermal water is unknown but is thought to be the geothermal outflow plume from the Valles caldera, a well known volcanic feature that hosts several hot springs and is near the site of the Fenton Hill Hot Dry Rock project.

Impacts A unique combination of technologies that if successful will lower overall exploration risk and will transfer LANL developed technology to the market.
Funding Source American Recovery and Reinvestment Act of 2009
