In recent years dual-sensor recording has been introduced to marine seismic acquisition with reported benefits such as the increased band-width of the acquired seismic signal, improved signal-to-noise ratios due to deep-tow streamers, and operational efficiency due to an increased weather window. This abstract describes another advantage of dual-sensor measurements, namely the opportunity it provides to better predict and subtract surface-related multiples from marine seismic data compared to using conventional data acquisition. Using a dataset from offshore Greenland, it is demonstrated that dual-sensor acquisition leads to a more accurate set of predicted multiples with respect to phase and amplitudes. As a result, the adaptive subtraction of the multiples can be carried out in a more constrained and robust manner, leading to better multiple elimination and better primary preservation.
