Abstract

Multi-channel surface NMR instrumentation and software, developed in the United States, has been applied to investigate 2D and 3D hydrology at various locations in the Western US. Two new multi-channel processing techniques, reference coil-based noise cancellation and T2*-weighted porosity imaging, are shown to increase effective signal to noise ratios by an order of magnitude or more. These effective SNR gains enable multi-coil surface NMR to produce useful and reliable images when the post-averaged SNR is less than 1, and at locations where<br>previous single-coil surface NMR investigations have failed. Experimental results are presented for recent field studies conducted in Nebraska, Minnesota, Iowa and Washington.
