Claim:
1. A computer-implemented method for use in processing seismic data for indications of hydrocarbon deposits, the method comprising: receiving acquired seismic data as a plurality of common shot gathers for a subterranean geologic formation; simulating seismic data that represents a common multisource gather for the subterranean geologic formation that correspond to a plurality of shots; for shot separated simulated seismic data, eliminating the simulated seismic data that are unmatched in the acquired seismic data to generated conformed simulated seismic data; performing, via a processor, a waveform inversion between the acquired seismic data and the conformed simulated seismic data; and based at least in part on the waveform inversion, estimating seismic velocities that indicate hydrocarbon deposits in the subterranean geologic formation.
