In this paper, we present real data applications of the acquisition and processing method outlined in the companion paper ( , Making the transition from discrete shot records to continuous wavefields – Methodology: Expanded abstract submitted to the EAGE annual meeting). We discuss the design of sources that emit continuous wavefields approaching the properties of white noise using air-guns. The design minimizes correlation between sources and allows a six-source configuration with a vessel towing six strings of air-guns, thereby increasing efficiency or cross-line sampling. The environmental benefit of spreading source energy in time will be demonstrated. We illustrate the processing method based on continuous source and receiver wavefields on seismic data acquired on top of data acquired previously based on discrete shot records. Both data sets will be compared at image level.
