Imaging the Perdido Fold Belt: A Case Study

We present a case history of depth imaging of the Perdido Fold Belt Basin, deepwater, western Gulf of Mexico. Geology in this area contains significant sediment folding, as well as the presence of highly rugose and faulted clastic and carbonate rocks in close proximity to salt. To properly image in this area, a processing flow consisting of surfacerelated multiple attenuation, proper compensation for attenuation, and several iterations of prestack depth migration and grid-based tomography were applied. We detail the processing flow, and give several examples of velocity model building and depth imaging obtained in this area.
