Understanding the local basin—achieved through integrating stratigraphic, structural, biostratigraphic, and geochemical data—is the critical scale of basin analysis for [[petroleum system]] identification. Reconstructing a basin's history, from regional [[tectonic setting]] to a single local basin, provides the geologic framework for defining exploration plays and prospects.

Throughout this chapter, the Gulf of Mexico (GOM) basin is used as the example of sedimentary basin analysis and the relationship of basin analysis to defining essential elements and processes of the petroleum system. By using only one example, the reader should be better able to focus on the process of data integration, which can be adapted or modified for other basin types. Aspects of plate tectonics and depositional history are used to define several scales of subbasinal entities and their relationship to petroleum source and reservoir rocks. A history of progressive growth faulting and salt mobility controls the formation of potential traps, the locus of sediment transport and accumulation, and potential avenues of hydrocarbon [[migration]] and accumulation.

The chapter progresses from largest scale to smallest scale ([[:file:sedimentary-basin-analysis_fig4-1.png|Figure 1]]). It begins with the entire GOM basin and concludes with a case history of the East Breaks minibasin petroleum system. The East Breaks minibasin is an example of play and prospect definition within the context of a subregional petroleum system within one subprovince of the GOM Tertiary basin.

[[:file:sedimentary-basin-analysis_fig4-1.png|Figure 1]] is a series of index maps for the GOM basin analysis example used in this chapter. Each map represents a different scale of sedimentary basin analysis, beginning with the largest (the GOM basin) and progressing to the smallest (the East Breaks minibasin).
