Geothermal Exploration Demo
Map Geothermal Systems from the Surface
This simulation shows how PWI's passive sensor network progressively reveals a geothermal system — from initial heat anomaly detection through full characterization of the salt dome, cap rock, and hydrothermal conduit at depth.

Progressive Discovery Timeline
Deploy & Listen
33 sensors deployed in a ring around the hot springs area. Within weeks, passive data accumulates and the first subsurface anomalies emerge.
Map the Structure
The salt dome footprint (3.3 km) and cap rock (839m) are resolved. Seismic interferometry confirms a velocity spike at the cap rock boundary.
Characterize the System
The hydrothermal conduit is located and sized. Brine pathways from dome to surface are traced. Full geothermal model delivered.
What You're Seeing
Salt Dome & Cap Rock
The beige dome structure is a salt diapir extending to ~1,165m depth. The gray shell at 839m is the cap rock — confirmed by a seismic velocity spike of 1,534 m/s.
Geothermal Conduit
The orange vertical cylinder is a hydrothermal conduit (598–781m depth, ~183m wide) channeling hot brine from depth to the surface hot springs.
Temperature Gradient
The colored points show subsurface temperature estimates derived from sensor data. The gradient increases from 35 to 102 °C/km as more data is collected and the thermal structure is resolved.
Why Passive Geothermal Exploration?
❌ Traditional Methods
- • Seismic surveys cost $500K+ and take months
- • Drilling exploratory wells: $1M+ per hole, months of permitting
- • Magnetotellurics gives resolution at 100s of meters
- • Point measurements miss spatial patterns
✅ PWI Geothermal Survey
- • Deploy 33 sensors in 2 days for a fraction of the cost
- • Continuous data — structure resolves progressively
- • 3D dome, cap rock, and conduit mapped from surface
- • Seismic interferometry confirms velocity structure
- • No active source, no permitting delays
