Benefits of Magnetic Resonance (NMR) compared to Electrical Resistivity in Brackish and Saline Groundwater Investigations

Benefits of Magnetic Resonance (NMR) compared to Electrical Resistivity in Brackish and Saline Groundwater Investigations

Geophysical NMR measurements deliver reliable and straightforward hydrogeologic information, even in saline groundwater environments. These environments can be challenging to characterize with conventional electrical resistivity measurements, because differences in resistivity may be associated with the fluid or with the formation. Low resistivity could be correlated with a impermeable clay, or […]

NMR Can Measure Groundwater Directly – Even in Permafrost Environments

NMR Can Measure Groundwater Directly – Even in Permafrost Environments

In permafrost landscapes, the ground remains mostly frozen throughout the year and liquid groundwater only occurs in certain locations or during anomalously warm periods. Understanding the spatial and temporal distribution of groundwater in these environments is extremely important as it can affect processes ranging from geotechnical soil stability to the […]

FastTIMES article: Surface and Borehole NMR as a Characterization Tool for Managed Aquifer Recharge

FastTIMES article: Surface and Borehole NMR as a Characterization Tool for Managed Aquifer Recharge

Nuclear Magnetic Resonance (NMR) is a powerful technology for groundwater investigations, leveraging the same physics as medical MRI imaging to directly detect water and characterize subsurface hydrogeologic parameters. In geophysics, surface NMR methods can be used to non-invasively map groundwater aquifers and borehole logging NMR tools can be used to […]
