AxioSubsurface
Below-Ground Asset Certification
The certification standard for what lies beneath the surface of the Earth.
AxioSubsurface applies the AxioTerra Standard to legacy oil and gas wellbores scored for critical mineral bycatch value beyond primary hydrocarbon reserves. The certification document surfaces value that is completely invisible to any valuation model built on primary hydrocarbon economics alone — and produces the institutional-grade documentation that makes that hidden value financeable.
Lithium Brine (DLE)
Produced water lithium concentration scored against DLE technology match for commercial viability. The primary intelligence layer for direct lithium extraction companies evaluating acquisition targets.
Geothermal Energy Conversion
Legacy wells pre-drilled to geothermal depth with zero drilling capex. AxioSubsurface certifies conversion potential and expected renewable energy output for geothermal developers.
CCUS Carbon Sequestration
Depleted reservoirs qualifying for Class VI EPA permitting under the Underground Injection Control program. Subsurface carbon storage generates carbon credits — a pathway entirely distinct from surface remediation.
Helium, Uranium ISR, Residual HC
Helium presence scored for strategic commodity value. Uranium ISR proximity mapped per the 2025 Critical Minerals List addition. Residual hydrocarbon reserves assessed against current recovery economics.
