Method for removing noise due to near surface scatterers

摘要

A set of raw common shot gathers are resorted as common receiver gathers. The wavefield envelopes from the common receiver gathers are migrated using one half the near-surface velocity to provide migrated data sets. The migrated data sets are resorted back into common shot gathers and subtracted from the original raw common shot gathers to provide coherent-noise-reduced data sets.
