Gulf Sub-Salt Seep Study Phases I and II

The Gulf Sub-salt Seep Study (1994), Phases I and II encompassed 97 cores on the outer Gulf of Mexico shelf, defining the boundaries of that sub-salt play. Previous coring along the shelf-edge had not revealed major seeps because seepage had not been associated with lateral petroleum migration along horizontal salt sheets. These surveys identified oil seeps around salt sheets associated with sub-salt discoveries such as Mahogany (Ship Shoal 349), primarily through the use of detailed 3-D seismic to site many of the core locations.

Deliverables for this study include PDF images of core logs (core locations and descriptions) and data volumes with the results of the following analyses: total scanning fluorescence, C15+ gas chromatography, C1-C4 hydrocarbons (headspace), and biomarker.
