Abstract
A method and system determines optimum azimuth parameters for seismic data processing. The method includes selecting a range of azimuth parameters, the azimuth parameters indicating the range of magnitudes and directions, each pair of azimuth parameters indicating a particular magnitude and a particular direction. The method further includes generating a plurality of seismic gathers wherein a seismic gather is generated from each pair of azimuth parameters, each seismic gather including a plurality of seismic data traces. The method further includes generating a plurality of seismic gathers for a plurality of imaging locations and a plurality of depths, each seismic gather containing a plurality of seismic data traces. The method further includes determining the coherence amplitude of each gather. The method further includes determining the gather having the optimum coherence amplitude, and selecting the azimuth parameters associated with the gather having the optimum coherence amplitude.
