Biostratigraphic techniques are commonly used in shallow environments of the Gulf of Mexico basin for depositional history modeling in petroleum exploration applications. Extending these interpretations to deep-water settings, where the structural and depositional history is more complex, is problematic. A localized study area was used for a case-analysis of a typically complex deep-water study area. A dataset of seismic, well-log, and biostratigraphic information was used to: (a) assess accuracy of the biostratigraphic interpretations produced by Fillon (2005), (b) determine specific pitfalls of micropaleontology as a tool in this environment, and (c) provide guidelines for the application of biostratigraphic data in the deep-water. Results indicate that the previous depo-history modeling did not account for local complexity, thus lessening utility at the petroleum exploration scale. Future studies in this environment should account for sections transported down-dip, isolation of depocenters, autocyclic variability, and reduce reliance on the condensed section as a chronostratigraphic tool.
