PGS kick-started the broadband revolution in 2007 when they found an engineering solution to the long-cherished industry ambition of towing collocated pressure and particle velocity sensors in a streamer. Thus, the receiver ghost effects can be completely removed, and new opportunities are created for processing, reservoir characterization and interpretation. In the six years since GeoStreamer was launched, the service company competitors have also launched a diverse family of broadband solutions using hydrophone-only streamers towed with either flat or variable depth profiles, using multicomponent streamers, or based upon processing-only solutions. Most recently, industry attention is turning to broadband source solutions so that true ghost-free seismic products can be achieved.
