Purposes of this Workshop:
1. To provide an alternative sequence stratigraphic approach for the establishment of a chronostratigrahic framework for the study of the interior salt basins of the northern Gulf of Mexico that are filled with Mesozoic post-rift non-marine to marine shelf siliciclastic and carbonate deposits.
2. To demonstrate the utility of this integrated biostratigraphic and sequence stratigraphic (based on T-R sequences) approach for stratal correlation, basin analysis, petroleum systems study, and the design of petroleum exploration strategies.
Formulation of an integrated sequence stratigraphic and biostratigraphic framework is fundamental for intra and inter basin stratal correlation, basin analysis, petroleum systems study, and the design of an effective strategy for oil and gas exploration in a sedimentary basin. For the interior salt basins of the onshore northern Gulf of Mexico area that are filled primarily with Mesozoic nonmarine to marine siliciclastic and carbonate deposits, a sequence stratigraphic classification using transgressive-regressive (T‑R) sequences and integrated with biostratigraphic data has utility as an approach for establishing such a framework. The sequence stratigraphy thus established for Upper Jurassic, Lower Cretaceous, and Upper Cretaceous strata is used to categorize facies associations and existing and potential petroleum reservoirs in the North Louisiana Salt Basin, Mississippi Interior Salt Basin, Manila Subbasin, and Conecuh Subbasin.
Transgressive aggrading eolian, fluvial, and coastal sandstone facies associations of the T-R sequences include highly productive oil and gas reservoirs in the Mississippi Interior Salt Basin, Conecuh Subbasin, and in the coastal waters area off Alabama. Productive reservoirs in these interior salt basins include regressive infilling fluvial to nearshore marine sandstone facies associations, and nearshore marine, shelf, ramp, and reef carbonate facies associations. Transgressive backstepping nearshore marine facies associations include highly productive reservoirs in the North Louisiana Salt Basin. These transgressive and regressive facies associations are recognized by their characteristic wireline log signatures and seismic reflection configurations. Knowledge of these wireline log patterns and seismic reflection characteristics assists in the identification of exploration targets.
