Pilots and Demonstrations: Next-Generation Field Tests and Drilling for New Resources

• Fervo Energy Company (Houston, Texas) — Drill, complete, and stimulate EGS wells in Elmore County, Idaho, deploy the first-ever high-temperature three-component geophone array at or above 200°C, and conduct advanced seismic and geochemical analysis in partnership with national labs. 
• Zanskar Geothermal and Minerals (Salt Lake City, Utah) — Design, drill, and hydraulically stimulate a short-lateral horizontal injection well at Lightning Dock Geothermal field in Hidalgo County, New Mexico, to deliver engineered pressure support to an actively producing hydrothermal reservoir and capture heat from impermeable, hot rock in the vicinity of the hydrothermal system 
• AlterG Resources (Salt Lake City, Utah) — Field validate technical performance of EGS at commercially relevant depths in Pershing and Churchill Counties, Nevada, using a deep horizontal EGS well pair and a comparative hydraulic stimulation program testing plug-and-perf and sliding sleeve completions 
• University of Utah (Salt Lake City, Utah) — Design, drill, stimulate, operate, and validate a high‑performance EGS doublet at the Dixie Valley West geothermal field in Nevada, with the aim to demonstrate that engineered reservoirs developed adjacent to existing hydrothermal systems can deliver sustained circulation, enhanced permeability, and commercially relevant thermal output 
• Quaise Energy (Houston, Texas) — Conduct field-scale EGS demonstration on southern flank of Newberry Volcano in central Oregon, with bottomhole temperatures of 265°–365°C—above the range where most conventional EGS tools and materials have been validated 

Sixteen projects are working on exploration drilling to gather the subsurface data needed to characterize and potentially confirm promising next-generation and conventional hydrothermal geothermal resources: 

• DAVINCI EP LLC (Denver, Colorado) — Drill and test two paired horizontal geothermal confirmation wells in the Brawley (California) Known Geothermal Resource Area to characterize a naturally enhanced hydrothermal reservoir without stimulation, identify parameters to support commercial-scale development of the resource, and provide a replicable framework for other naturally fractured geothermal basins 
• University of Utah (Salt Lake City, Utah) — Conduct targeted drilling and subsurface characterization of a large thermal anomaly in Utah’s Cove Fort geothermal field and use modern drilling, logging, and data integration techniques to better understand how heat and fluids are distributed in carbonate rock formations 
• Zanskar Geothermal and Minerals (Salt Lake City, Utah) — Test and document a confirmation methodology of directionally-drilled, deep wells from a single pad, using near-real-time stochastic model updates and logging-while-drilling to reduce anomaly-to-discovery timeline, and confirm a commercially viable hydrothermal resource at a Basin and Range site that has never been drilled to reservoir depth 
• Fervo Energy Company (Houston, Texas) — Execute a targeted appraisal campaign at a high-priority EGS prospect in Humboldt County, Nevada, drilling to confirm reservoir temperatures of 200–220°C  
• San Ildefonso Services LLC (Santa Fe, New Mexico) — Drill a pre-feasibility geothermal exploratory well in the San Ildefonso Pueblo, New Mexico, on the eastern border of the Jemez Mountains volcanic field in the Rio Grande Rift, and collect basement core and data from injection tests and logging 
• GeoAlaska LLC (Anchorage, Alaska) — Drill, core, log, and test a geothermal confirmation well on the southern flank of Mt. Augustine, a volcanic island in lower Cook Inlet, Alaska, and characterize the subsurface reservoir using a shallower well targeting >150°C and a deeper well targeting >350°C 
• Hexagon Energy LLC (Charlottesville, Virginia) — Drill an exploration well in Washington’s Wind River Valley, targeting temperatures >150°C, and collect, test, and publish downhole data sufficient to design a commercial-scale geothermal drilling and power generation program 
• GreenFire Energy Inc. (Oklahoma City, Oklahoma) — Confirm and characterize deep geothermal resource potential in Sierra Army Depot (California) by siting and drilling a vertical well targeting 204°C and integrating legacy data, geophysical surveys, drilling, reservoir testing, and modeling 
• TLS Geothermics Corp (Reno, Nevada) — Drill a confirmation well in Nevada targeting >204°C, using polycrystalline diamond compact drill bit technology in faulted crystalline rock, and develop and calibrate a 3D model linking magnetotelluric resistivity to temperature and permeability 
• LiPower Geothermal, LLC (Gloucester, Massachusetts) — Construct two wells, a production well and a reinjection well, to complete a Definitive Feasibility Study on an under-explored geothermal resource in the South Brawley New River area (California)  
• INTEK Inc (Arlington, Virginia) — Site and drill two reservoir-depth wells into the geothermal resource at Pisgah Crater (California) and collect data to characterize and confirm the resource, determine power production feasibility, and accelerate opportunities for commercial-scale geothermal power at the site 
• Oriah Geothermal, LLC (Fort Worth, Texas) — Evaluate a next-generation geothermal resource in eastern Oregon through staged drilling of thermal-gradient wells to constrain the thermal regime and refine subsurface targets, followed by a reservoir-depth exploration well, advanced diagnostics, and integrated reservoir modeling 
• XGS Energy Inc. (Palo Alto, California) — Drill deep vertical appraisal well in Socorro County, New Mexico, acquiring downhole temperature, logging, core, and continuous electronic drilling record data to validate subsurface datasets, update thermal and geologic models, and assess resource suitability 
• Raser Power Systems, LLC (Reno, Nevada) — Assess opportunity for increased power generation from Thermo No. 1 geothermal power plant in Utah’s Escalante Desert by drilling an exploratory well in the southern fault intersection zone and conducting wellfield interaction monitoring between the exploration well and an existing well 
• 400C Energy Inc. (Denver, Colorado) — Re-enter and deepen an existing geothermal well in Beaver County, Utah, to determine whether the Salt Cove area contains an extension of the nearby Roosevelt Hot Springs hydrothermal system, a high-temperature next-generation geothermal resource in hot crystalline rock 
• Invenergy Geothermal Development LLC (Chicago, Illinois) — Validate hybrid hydrothermal–EGS potential near Grand View, Idaho, by drilling a deep temperature confirmation well to confirm subsurface temperature profiles, evaluating permeability indicators, and collecting high-resolution geologic and geophysical data 

Data generated by these projects will be publicly available through DOE’s Geothermal Data Repository (GDR), giving industry, researchers, and other stakeholders access to information from the field tests and geothermal exploration activities. Making these data available can extend the value of the projects beyond individual sites by helping inform future technology development and geothermal exploration across the industry.
