A synthetic study of SNMR tomography with complex data

Surface Nuclear Magnetic Resonance (SNMR) is a relatively new geophysical method for groundwater exploration and aquifer characterization. So far, the practical application of SNMR technique is mostly based on 1-D forward and inversion strategies, which are inappropriate for investigating isolated water occurrences and using in complicated hydrological environments. What’s more, most of the inversions only employ the real part of the voltage response data. In order to expand the application scope and inversion resolution of SNMR method, we investigate a 2-D forward and inversion scheme considering the elliptical polarization and phase lag effect , and apply it into the tomography of 4 synthetic aquifer models with complex data.
