Abstract
Embodiments use seismic processing methods that account for the spatial variability of surface wave velocities. Embodiments analyze surface wave properties by rapidly characterizing spatial variability of the surface waves in the seismic survey data (). Filtering criteria are formed using the spatial variability of the surface waves (). The filtering criteria can then be used to remove at least a portion of the surface waves from the seismic data (). The rapid characterization involves estimating a local group velocity of the surface waves by cross-correlation of the analytic signals ().
