We expect that statics and other parameters can be reliably estimated using beamformed data with the proposed corrections and successfully applied during reprocessing of the original data. In the second field data example we demonstrate how the proposed approach...

... cables too short are typi- cally used for a variety of reasons. After determining the needed offset range by field experiment, a long offset seismic line was acquired in 1982 to test the usefulness of the seismic refrac- tion technique for solving the offshore delta statics problems.

... static corrections in complex regions. Introduction Because of poor S/N ratio of reflection in complex regions, the QC of field static corrections by first break is often carried out on common-shot-point (CSP) gather. Conventionally, the calculation of field static corrections is to calculate to a...
