NMR Technology

Water Controls Everything
We Do with the Earth

From the stability of construction excavations to the movement of contaminants through soil, from agricultural productivity to mining safety—subsurface water governs the success or failure of nearly every project that interacts with the ground beneath our feet.
Yet for decades, we’ve been forced to infer water content indirectly, relying on electrical conductivity, seismic velocity, or electromagnetic response to guess at what’s really happening below the surface.

Nuclear Magnetic Resonance (NMR):
Direct Measurement of Subsurface Water

NMR geophysics is the only technology that directly detects and quantifies hydrogen atoms in subsurface water molecules—delivering precise, lithology-independent measurements of the critical hydrogeologic parameters that control how water behaves underground.

What makes NMR different:

  • Direct water measurement – No interpretation guesswork; NMR measures actual water content
  • Distinguishes mobile vs. bound water – Calculate hydraulic conductivity and specific yield on-site
  • Lithology-independent – Accurate in sand, clay, fractured rock, or mixed formations
  • Non-invasive profiling – Characterize aquifers before drilling, reducing exploratory costs
  • Flexible deployment – Surface systems, borehole logging tools, and direct-push configurations
