Simultaneous source acquisition promises great efficiency gains but its suitability for reservoir monitoring applications remains contested. By utilizing an approach for simultaneous source acquisition, based on a novel view of seismic data sampling principles that is completely different to existing methods, we demonstrate that 4D-grade seismic data can be obtained from an OBS field data set acquired in the North Sea. Main drivers for developing this new simultaneous source technique are to create significant cost savings and increased flexibility in data acquisition for reservoir monitoring applications.
