• This paper develops a new method of redatuming the observed data from the actual receivers into the virtual receivers.
• The method provides a model based interpolation/extrapolation technique for electromagnetic data.
• The method can be used for reducing the distortion of electromagnetic field data caused by the nearsurface inhomogeneities.
We present a new method of analyzing controlled-source electromagnetic (CSEM) data based on redatuming of the observed data from the actual receivers into the virtual receivers. We use the Stratton–Chu type integral transform to calculate the EM field in the virtual receivers. The virtual receivers can be placed at any desirable position, including close to the target, which increases the sensitivity of the EM data to the target. The developed method provides an effective model-based interpolation/extrapolation tool for electromagnetic field data. This paper demonstrates that redatuming can be used for designing the optimized CSEM survey configuration. The numerical examples, for the Kevin Dome Electromagnetic Project Site, illustrate the practical effectiveness of the developed method.
