Method for seismic data processing using depth slice decomposition

Abstract From the Canadian patent

A method of processing geophysical data on a parallel processor involves decomposition of an analysis cube into depth slices a second decomposition of , a data acquisition cube into traveltime slices and determination of a , variably dimensioned analysis aperture. Precomputed traveltimes are stored in packed format to minimize storage volume and data bandwidths. A processing simulation is performed to optimize the stored sequence of the seismic trace data and to minimize traveltime input/output demands. The method preferably assigns input/output, analysis, or control tasks to each processor with depth , and traveltime slices assigned to each analysis processor. The method relies on …
