Method that acquires seismic data in a region having time restrictions. The method includes deploying first and second seismic vessels having first and second seismic sources, respectively; separating the first and second seismic sources from each other by a predetermined distance d; towing the first and second seismic sources across the region while maintaining the predetermined distance d; shooting simultaneously the first and second seismic sources; and recording seismic signals corresponding to the first and second seismic sources. The predetermined distance d is calculated so that first seismic signals corresponding to the first source are recorded during an actual recording portion while second seismic signals corresponding to the second source are recorded during a recording lag portion, which is later in time than the actual recording portion. |
