IP Imaging with Multi-Frequency Data – Preliminary Study

IP method has ability of providing valuable information about the structural and hydraulic nature of porous media and fluids contained with such media. To date most IP interpretation technique uses only the chargeability property. In principally IP can give more valuable information about subsurface structure. Using complex resistivity (conductivity) approach, it provides the improved lithological characterization, since surface polarization effects are separated from electrolytic and surface conduction effects. In this study, we develop IP inversion technique using complex resistivity and expand it to the multi-frequency data set. Inverting multi-frequency data set with appropriate object function, it may enhance the noise characteristics of whole data set and enable more accurate estimation of hydraulic and structural parameters.
