A technique includes receiving seismic data acquired by an array of seismic sensors during a towed marine survey of a subsurface and performing migration velocity analysis to determine a background velocity model of the subsurface based at least in part on particle motion derived from the seismic data.

Migration velocity analysis using seismic data

This invention discloses methods of processing data using a computer to separate out geophysical exploration response at receivers corresponding to one source among many sources by determining at least one spatio-temporal variant directional propagation attribute of the responses at receivers corresponding to the one source and by decomposition or filtering process using the determined attribute.

Methods to process seismic data contaminated by coherent energy radiated from more than one source

A technique includes obtaining seismic data acquired by at least one seismic sensor. The technique includes processing the seismic data to determine a value that is indicative of a three-dimensional directional propagation attribute of a seismic event based on the seismic data.
