Sub-surface water targeting at scale.
Saudi Arabia's hydrogeology is dominated by deep sandstone aquifers and structurally-controlled alluvial systems. Identifying productive zones at borehole scale requires more than satellite remote sensing or surface geology — it requires direct measurement of sub-surface conductivity.
Our airborne EM systems image conductivity to 400 m depth at survey speed, resolving the contrast between freshwater aquifers (high resistivity) and brackish/saline zones (high conductivity). Magnetic and gravity data add structural context — fault networks that control aquifer recharge and connectivity.
The deliverable is not a map — it is a ranked list of drill-site recommendations, each with its supporting geophysical evidence, predicted water quality, and confidence band on the productive horizon.
3D conductivity model
Stitched conductivity curtains beneath flight lines, isolating a productive freshwater aquifer between resistive basement and conductive overburden.
Structural recharge corridor
1D laterally-constrained inversion → 3D blocky model build → fault-corrected interpretation → drill-target ranking → water-chemistry prediction (TDS proxy).
From conductivity map to productive borehole.
