Abstract
Method and systems are provided for processing c-wave data resulting in less sensitivity to errors in p-wave velocity analysis. Therefore, according to one aspect of the invention, a process is provided for processing c-wave data, the process comprising: providing zero-offset gather without a hyperbolic movement correction; performing migration on the zero-offset gather; performing velocity analysis on the migrated zero-offset gather; and performing NMO on the migrated data using the velocity from the velocity analysis.
