Abstract

Coverage gaps are very common in marine 3D seismic data acquisition. The size of coverage holes is small at near offsets and gradually increases at middle and far offsets due to streamer feathering. To recover the lost data in these coverage holes, infill has to be planned. Improper infill planning escalates the project cost, turnaround time and HSE exposures at sea. Optimization of infill based on geophysical criteria is crucial without compromising on data quality
