Patent ID: 8219321

Claim:
A computer-implemented method of processing seismic data, the method comprising: receiving, at a server, a request for a beam table that corresponds to a table location on a geographic surface from a processing node that is processing seismic data for migration, wherein the beam table is a record of one or more beam parameters of one or more beams that form seismic wavefronts arriving at or near the table location; determining, at the server, whether the requested beam table is included in a set of stored beam tables, wherein the set of stored beam tables includes one or more beam tables stored externally from the processing node; and initiating, by the server, transmission of the requested beam table to the processing node if the requested beam table is included in the set of stored beam tables and if the requested beam table is not included in the set of stored beam tables, initiating, by the server, transmission of information to the processing node that initiates computation of the requested beam table by the processing node.
