ABSTRACT:
Implementations of various techniques for processing seismic data acquired by three or more over/under streamers. In one implementation, the seismic data may be processed by grouping the seismic data into one or more sets of seismic data based on all possible pairs of the three or more over/under streamers, wherein each set of seismic data comprises seismic data that had been acquired by a pair of the three or more over/under streamers, applying a shift and subtract algorithm to the one or more sets of seismic data, and applying a dephase and sum algorithm to the one or more sets of seismic data.
