The seismic data processing workflow:

• Reformat SEGD / SEGY field tapes in CGGV internal format
• Merge seismic/Navigation data & QC
• Acquisition-flagged trace edition
• Deterministic zero phase de-signature
• Low-cut filter, if required mild kf-filter with cut-off velocity 1300m/s
• Amplitude extractions
• Receiver & Shot statics and Instrument delay compensation
• Tidal statics
• 2 passes of Swell noise attenuation
• Interactive and automatic editing
• Automatic de-spiking and cable burst suppression
• Deterministic compensation for gun drop-out test
• SEGY output pre-processed shots and QC
• Bin sorting
• QC of the final velocity field from the most recent seismic reprocessing done by SHELL in 2008 on both 1997 and 2008 volumes (inspection of NMO-corrected gathers), if required adjustment to obtain a 3D stacking velocity field
• Full data stack & production of near-trace cube & QC
• SEGY output of full stack after pre-processing & QC

ОСОБЕННО беспокоят "Acquisition-flagged trace edition", "gun drop-out test", "kf-filter", "Bin sorting", "cable burst suppression".
Заранее большое спасибо всем!
