Delivering NMR Excellence

Vista Clara is the global leader in developing, delivering and supporting advanced Magnetic Resonance (NMR) tools for groundwater detection and hydrogeologic characterization.

Across Multiple Industries

Our advanced NMR technologies are used in many industries including:

  • Groundwater Resources
  • Environmental Remediation
  • Mining
  • Geotechnical & Construction

What is NMR?

Magnetic Resonance (MR) refers to a technique in physics known as “Nuclear Magnetic Resonance” or NMR. In geophysical applications of magnetic resonance, a high-voltage electrical current is pulsed through a coil of shielded wire at a specific frequency—the resonant frequency of hydrogen nuclei.

This enables highly accurate detection of groundwater characteristics, including porosity, pore size, bound & mobile water content, hydraulic connectivity and more.  Vista Clara’s NMR instruments enable high resolution direct detection of groundwater using borehole logging, non-invasive surface detection, and hand-portable tools.

GMR is the ONLY non-invasive geophysical method that directly detects groundwater from the surface and directly quantifies volumetric water content.

GMR differentiates moveable water in large pores from immoveable water in small pores and provides high vertical resolution to depths of up to 500 feet (150 meters).
