Summary:
Reprocessing and reimaging legacy surveys can add significant value to existing seismic data sets while eliminating the requirement to acquire new data. During reprocessing work, an appropriate strategy must be set early on with the required technologies included in the processing flow to ensure that the desired uplift over the legacy seismic images is achieved. We present a case study of reprocessing and reimaging a legacy data set with the clear objective of enhancing the reservoir understanding. The broadband processed data, coupled with a tailored model building and depth imaging workflow, led to delivery of a clearer, more interpretable image, relative to the legacy processing. This image provided significant assistance and insight to the asset and interpretations teams in their evaluation of the field geology and reservoirs.
