Recently, a method was introduced that uses non-linear optimization to derive a stable operator which, when applied to conventional marine streamer seismic data, recovers much of the signal present in the recorded data that is weakened by the presence of the ghosts at the notch frequencies. In this paper, we present a case study of the use of such a method to derive a broadband image from conventionally acquired data from offshore West Africa.
