A small-diameter nuclear magnetic resonance (NMR) logging tool has been developed and field tested at various sites in the United States and Australia. A novel design approach has produced relatively inexpensive, small-diameter probes that can be run in open or PVC-cased boreholes as small as 2 inches in diameter. The complete system, including surface(More)
The properties of hydrogeological units depend on their formative processes and history. A good understanding of how hydrogeological units are formed is essential to accurately characterise their geometry and properties. Accurate characterization is necessary for the robust models needed for applications such as groundwater extraction, waste water disposal,(More)
