We describe a new and unique workflow that incorporates seismic horizons into the CSEM inversion. The workflow provides high resolution 3D resistivity models that are consistent with measured vertical and horizontal resistivity logs and seismic inversion results. Since it neither assumes knowledge about the background resistivities nor the existence, size and shape of resistive anomalies, the workflow is also applicable in a frontier exploration setting. The high resolution inverted resistivity models from the Skrugard 2011 dataset show that CSEM can map brine filled, high porosity sand reservoirs and channels which here act as conductive anomalies. Another finding is that the sub surface resistivity around Skrugard is highly anisotropic and must be properly accounted for to avoid inadequate inversion results.
