Abstract:
1. A method of recording multiple marine seismic signals comprising: a) deploying two or more independent phase encoded vibrational seismic sources, and three or more seismic receivers spaced the same substantially common distance from one another into the water to be towed by a boat; b) while in motion, transmitting multiple simultaneous sweep signals from the independent phase encoded seismic sources; c) while in motion, recording multiple simultaneous phase encoded seismic signals (b); d) inverting the recorded seismic signals in (c); e) separating signals at each receiver into separate source specific signals; and f) taking the source-receiver pair signals and stacking them based on a substantially common location of the respective sources and receivers at the time of the respective sweep so as to correct for the motion of the sources, receivers and common mid points.
