Man-portable NMR tools enable direct measurement of volumetric water content and high-resolution pore-scale analysis of soils, sediments and core samples. These tools are all man-portable and designed for use in the field.
- The Helios™ Soil and Core Sample Analyzer enables measurement of a wide range of soil and core samples, with diameters up to 4 inches, and with a unique combination of short echo spacing, wide bandwidth and low static field strength to mitigate the effects of magnetically susceptible rocks and soils
- The Discus™ sensor provides rapid, non-invasive measurement of near surface soil moisture content, with the ability to profile water content in four separate depth zones ranging from 1 inch to 8 inches (2.5 to 20 cm). The Discus uses a battery-powered NMR control unit, that can be carried in one hand and operated outdoors in all weather conditions
These man-portable instruments provide direct, low-cost, high-resolution measurements of hydrogeological properties that users really care about, including:
- Volumetric water content
- Pore size distribution
- Bound and mobile porosity
- Hydraulic conductivity
- Transmissivity
A single NMR log can provide all of these key hydrogeological properties at vertical resolution on the order of 25 to 50 centimeters (10 to 20 inches), enabling unambiguous and precise characterization of the water storage and pore structure characteristics of any earth formations.
