A merge of two legacy surveys representing 3500 km2 of marine data from West of Shetland have been reprocessed using the latest available broadband processing sequences and technologies such as offset dependent cold water statics, 3D multi-shot joint deghosting, 4D regularization, and amplitude versus angle compliant spectral enhancement. The result demonstrated successful application of the high-end tailored processing sequence on legacy conventional data, acquired in 1993, can lead to a significant uplifted broadband image with better resolution at shallow and more interpretable structures at depth for reducing the risk for oil and gas exploration.
