We created a workflow to predict controlled-source electromagnetic (CSEM) responses from seismic velocities and compared the predicted with CSEM data. The first step was calculate resistivity model in Bayesian framework account for uncertainties. second estimate electric anisotropy improve depths at which there no well control. last use this updated forward-model compare result comparison real data revealed that measured were generally within plus minus one standard deviation of responses. This able responses, can prove very useful feasibility studies before acquisition interpretation after
