  • Borehole nuclear magnetic resonance (NMR) is an emerging geophysical method being applied to hydrogeology investigations. NMR is a quantitative geophysical method that can be used to make in situ assessments of porosity, water content, mobile and immobile water fraction, and estimates of permeability. While borehole NMR is commonly used in the oil and gas industry, it is only recently that NMR tools have been designed for use in small-diameter boreholes that are typically used in groundwater studies. This video presents an overview of borehole NMR and example applications for environmental site management.
