Patent ID: 8060312

Claim:
A system configured to process seismic data, the system comprising: a plurality of processing nodes configured to process seismic data for migration, wherein each processing node comprises: a migration module configured to determine an image of the seismic volume beneath the geographic surface, wherein the determination is based at least in part on one or more beam tables, and wherein a beam table corresponds to an imaging location on a geographic surface of the seismic volume of interest and is a record of one or more beam parameters of one or more beams that form seismic wavefronts arriving at the imaging location; and a table module configured to obtain beam tables for the migration module; and a server that is operatively linked to each of the plurality of processing nodes to enable communication between the server and the processing nodes, and wherein the server comprises: a query module configured to receive a request from the table module of one of the processing nodes for a beam table corresponding to a table location on the geographic surface of the seismic volume of interest, and to determine whether the requested beam table is included within a set of stored beam tables, wherein the table location on the geographic surface is determined by the requesting table module based on the imaging location identified in a request for a beam table from the migration module associated with the requesting table module; and a query results module configured to initiate access of the requested beam table by the requesting table module if the requested beam table is included in the set of stored beam tables.
