Gulf Basin Depositional Systems
The Gulf of Mexico basin is perhaps one of the best studied basins in the world. Most of the work, however, has been concentrated around the periphery of the basin where historically oil and gas have been produced. There is still much to be learned about the deep basin fill as well as how the depositional history of the basin explains and predicts reservoir distribution patterns. The exploration successes and rejuvenated interest in the Paleogene plays, sub-salt stratigraphy, and deep gas exploration potential continue to make the GBDS project especially timely.
The UT Gulf Basin Depositional Synthesis Project (GBDS) is an ongoing, industry-supported, comprehensive synthesis of Cenozoic and Mesozoic fill of the entire Gulf of Mexico basin. The results are distributed as a digital data base that is updated regularly. The project has led to major new contributions to the understanding of the depositional history and framework of the Gulf of Mexico Basin (see bibliography below). The project has focused on refining sequence correlations between the continental margin and deep basin stratigraphies, mapping sedimentary transport axes and paleogeographies through time, defining the evolving roles of submarine canyons, retrogradational margins, and shelf-margin delta systems in localizing in time and space sand transport to the slope and abyssal plain, and better understanding regional controls on reservoir facies and their deposition.
The deliverables for the project include a digital set of regional UTIG multi-channel seismic transects in the deep basin (traversing both U.S.A. and Mexico waters), a comprehensive GIS database, a suite of regional lithofacies and depositional systems maps generated from the data base and compilation of published information, and an extensive supporting bibliography. The maps encompass the entire Gulf of Mexico basin and currently cover the time period from the early Paleocene to the Quaternary. Also included are a series of regional cross sections based on seismic and well control to illustrate the major geologic features and depositional relationships. These data together provide a comprehensive picture of Gulf-wide Cenozoic sedimentary history. Moving forward we are expanding to the Mesozic and are currently building a database and framework for the period.
