Development of a NMR-Borehole Tool for Groundwater Detection and Aquifer Characterization
Funded by the German Federal Ministry of Research and Technology the LIAG together with two Fraunhofer Institutes (IBMT and IZFP), Antares Datensysteme GmbH and Bohrlochmessung-Storkow GmbH is about to develop a NMR-Borehole tool for near surface groundwater applications.
Due to is unique sensitivity on hydrogen proton nuclear-magnetic-resonance is an outstanding technique for not only groundwater applications. NMR is able to directly detect water and measure the volumetric water content. Besides this, NMR can help to estimate the hydraulic conductivity of the subsurface using empiric relationships.
The technique of borehole-NMR is proven to be useful over years by the oil and gas industry allowing for detailed site characterization. However the available tools are far too large, heavy and cost intensive to be used in small business of groundwater management. Therefore, the project aims to develop a tool that meets the requirements of groundwater applications, i.e., length, weight and diameter. This means to develop an advanced design of coil and magnet as well as energy efficient pulse sequences.
