Abstract / Description of output

Electromagnetic tools are widely used for high resolution subsurface characterization because of their noninvasive character and the fairly quick measurement acquisition. Conventional inversion tools are often based on approximations that include far-field, high-frequency ray-based approximations, and often only part of the data is used. Due to the increased computation power, accurate forward modeling programs can now be used for advanced inversion algorithms where the complete measured data is used. Here, we discuss recent developments in quantitative ElectroMagnetic Induction (EMI) and Ground Penetrating Radar (GPR) inversion that yield high resolution of quantitative medium properties. First, we show that calibrating EMI data using an electrical resistivity tomography (ERT) transect returns quantitative measurement values which enable a two-layer inversion that reflects the lateral and vertical conductivity distribution of the subsurface. Next, we discuss the latest developments of GPR full-waveform inversion that uses all information content present in the data and returns sub-wavelength resolution.
