What TEVERRA does

TEVERRA (formerly Petrolern), headquartered in Atlanta, Georgia, is a subsurface solutions and applied geoscience company that develops technology and consulting services for geothermal energy, carbon capture and storage (CCS), oil and gas, and energy storage projects. Founded in 2019 and supported by SBIR grants from the U.S. Department of Energy and NSF since inception, the firm serves enterprise energy developers, U.S. federal agencies (notably the Department of Defense Defense Innovation Unit), state energy offices, data center operators seeking thermal management solutions, and rural communities pursuing geothermal-based heating and cooling. Named customers and partners include TLS Geothermics, the Colorado Energy Office, Earth Energy Explorers, and Premier Corex.

The company's product portfolio centers on an integrated subsurface technology stack. Flagship offerings include GeoDeck™, a web-based VR/AR subsurface visualization platform recognized with a DOE SMART Prize; ResStor™ and Cold-ResStor subsurface thermal energy storage systems; ConvertDeck for converting oil and gas wells to geothermal use; and specialized downhole tools including DDG (drilling dynamics geomechanics), MMARCT (EGS fracture monitoring), DFISS (direct in-situ stress measurement), FluidTrack, CompressDeck, and CarbonWatch. Underlying capabilities span geology, geomechanics, rock physics, computational mechanics, signal processing, and applied AI, including physics-informed machine learning applied to DAS/DTS, seismic, microseismic, and well log data for predictive reservoir analytics and real-time monitoring.

TEVERRA generates revenue through a hybrid mix of government contracts and grants (SBIR awards, DoD contracts, state energy office grants), professional consulting services (reservoir management, geomechanical modeling, project advisory), technology licensing and deployment, and customized training programs. Cumulative disclosed grant inflows total approximately $5M since 2021, with a 5-year DoD contract at Fort Wainwright, Alaska representing the largest multi-year revenue anchor. In June 2026 the company spun out EnEarthia, a wholly owned subsidiary commercializing the ResStor thermal energy storage platform for data center and industrial cooling, which is preparing for a Series A fundraising round to scale deployment.
