Broadband marine towed streamer seismic has become the technology of choice for exploration seismic because of the multiple benefits it offers. Current broadband technologies can be divided into three classes: (1) multicomponent streamer systems that facilitate wavefield separation; (2) acquisition methods using conventional hydrophone only streamers that utilize the notch diversity inherent to slant streamer depth profiles, or simply a deep flat tow configuration with the energy restored in the notches; (3) processing solutions that can be applied to any old or new conventional data set, in which notches in the passband are eliminated by a variety of processing solutions. The focus of this presentation is on the multicomponent-streamer solution that uses wavefield separation. It is the most robust method and it offers unique additional benefits beyond simply low and high frequency extensions of the overall signal bandwidth.
