AB  - The marine Controlled Source Electromagnetic Method (CSEM) has been used as exploration technology in the oil and gas industry. Inversion is the most widely used technique for interpretation of electromagnetic data. Nonetheless, resistivity images obtained from CSEM data generally have low resolution creating difficulties in the accurate characterization of geological reservoirs (containing hydrocarbons or for CO2 storage for example). Here is shown that by integrating a velocity field to guide the CSEM inversion leads to better focused resistivity images reducing ambiguities and source-receiver footprint. The proposed method integrates velocity models obtained through seismic full waveform inversion, in a constrained inversion algorithm for controlled source electromagnetic data. A synthetic example using a modified version of the Marmousi model is presented to validate the proposed methodology.
