COMBINED INTERPOLATION AND PRIMARY ESTIMATION

摘要

A method for combined interpolation and primary estimation can include performing a plurality of interpolations on received seismic data, performing a plurality of primary estimations on the received seismic data, and performing a combination of interpolation and primary estimation. Performing the combination can include generating reestimated primaries via a second primary estimation with input of a second interpolation, where output of the first primary estimation is input to the second interpolation.
