Frequency Soundings at Low Induction Numbers: Transformation and 1D Inversion Comparing to 2D ERT Inversion

The paper is devoted to an approach for calculating an apparent resistivity and a layered earth parameters from transformation and inversion of FEM soundings data. First part of study presents theoretical estimation of the sounding capability of the multifrequency sensor at simple layered earth model. Second part includes processing of the both FEM and DC ERT data sets collected at the same profiles. The results of transformation and 1D layered inversion of frequency soundings comparing to 2D ERT inversion are considered.
