This regional case study is based on interpreting a regional (71,000 km2) 3D wide-azimuth, broadband depth-imaged seismic reflection volume in water depths from 250 m to 3750 m. We demonstrate the presence of deepwater depositional systems extending for 370 km from the present-day shelf margin. Moreover, we illustrate how salt and regional tectonic events controlled the distribution and architecture of deepwater depositional systems during the evolution of the Salina del Istmo Basin, offshore Mexico. The deepwater depositional systems identified and interpreted based on seismic stratigraphy and geomorphology represent the key Eocene, Oligocene, and Miocene reservoirs in the area. Our findings provide significant exploration insights for oil and gas operators interested in areas basinward from the 2017 Zama-1 oil discovery.
