Wide Azimuth seismic data has proven to be an important exploration tool for understanding trap definition and reservoir risk in structurally complex salt basins across the globe. In this study we present results from the analysis of over 70,000 square kilometers of recent Wide Azimuth seismic data from the deepwater Salina del Istmo region of Campeche. A regionally consistent processing methodology integrating information from available wells and potential fields data has resulted in a data set which provides a unique regional perspective in this complex area. Regional mapping has led to the recognition of several distinct structural domains in the Salina Basin based on structural and stratigraphic styles. The dominant types of trapping geometries observed can vary significantly from one structural domain to another. We present examples where improved image quality from the Wide Azimuth data compared to reprocessing of legacy data results in increased confidence in trap definition leading to reduction of exploration risk.
