In this paper a SkyTEM dataset was used to show the advantages to enterapriori info into the inversion process. They determinean improvementin the resolution of those parameters having low sensitivity, more credible results, better match with ancillary information and easier data integration for derived products. Theapriori info can contribute also to recalibrate the AEM dataset.Thanks to stratigraphic and hydrogeological information provided by some boreholes, we usedas apriorithe elevations of some of the hydrogeological units, as defined by the hydrogeologists.The apriori info contributed to resolve better the shale impermeable bedrock of the aquifers and the depth and resistivity of the main aquifers. A preliminary analysis shows a promising correlation, which needs to be investigated in greater details, between electrical resistivity, transverse resistance and recommended pump rate.
