The AZGS Energy Geology group’s mission is to identify and characterize the subsurface geologic resources in Arizona. To this end, the team, led by Brian F. Gootee and including Lisa A. Thompson and Tawnya C. Wilson, develops and executes research projects focused on surface and subsurface geologic resources in Arizona’s many sedimentary basins. These resources include subsurface and on-surface carbon dioxide utilization, storage and mineralization; subsurface hydrogen and other gas storage in bedded salt deposits; critical mineral resources (e.g. helium, potash, volcano-sedimentary lithium, etc.); geothermal energy; shallow groundwater; and deep saline groundwater.
Ongoing projects include:
- AZ Geothermal Data Catalog & Resource Evaluation
- Southern Arizona CO2 storage complex feasibility in Harquahala basin (in negotiation)
- Southwest Regional Direct Air Capture (SWRDAC) Hub
- Four Corners Regional Initiative
- Carbon Utilization and Storage Partnership (CUSP)
Recently completed projects include:
- Distributed mafic rock resources for carbon mineralization in Arizona (MRRI)
- Arizona Orphaned Oil and Gas Well Program - Data Preservation Project (ADEQ)

A top priority of the Energy Geology group’s research is to collaborate with industry stakeholders, energy companies, and state agencies, and to increase public awareness of Arizona’s subsurface geologic resources. These efforts include geologic risk assessments to ensure wise and prudent use of our state’s natural resources.
The goals of this group are to:
- Provide scientific outreach, education and two-way engagement with Arizona stakeholders.
- Identify and characterize suitable sites in Arizona for a large-scale gas storage complex that evaluates distributed energy systems such as: durable long-term underground hydrogen storage (UHS), enhanced geothermal system (EGS), carbon capture and storage (CCS), saltwater disposal potential, direct air capture and mineralization (DAC to mineralization), and critical minerals.
- Continue to close data gaps in priority basins by collecting new data such as geophysics, drilling, geologic mapping, and analyses.
