Salt diapirism to very shallow depths below seabed in the deepwater Gulf of Mexico Puma appraisal area has extensively tilted, thinned and faulted supra-salt strata, and permitted the migration of asphalt, oil and gas to the seafloor and into the water column. Hydrocarbon migration through the shallow strata has resulted in the formation of extensive areas of authigenic carbonate at, and immediately below, the seabed interface. Active hydrocarbon seepage continues to feed chemosynthetic fauna across much of the Puma area. However, population densities are sparser than might be expected based on the extent of authigenic carbonate interpreted from geophysical data.The integration of surface seismic and autonomous underwater vehicle geophysical data, synthetic aperture radar imagery acquired via satellite, and extensive video acquired in two remotely operated vehicle surveys, has been used to delineate the extent of the above geological and biological relationships to support exploration and appraisal activities in the Puma area. In areas of benign seafloor such extensive site investigation work would not be required. However, the evaluation of areas with complex shallow geology and rugged seafloor that may host environmentally sensitive fauna over extensive areas will benefit from the integrated approach described below.Puma Area. The Puma prospect was successfully tested by the Green Canyon (GC) Block 823 #1 well in 2003 ( Figure 1). The discovery well was followed by two appraisal wells (GC821 #1 and GC866 #1) which finished drilling in 2007. Reservoir level field appraisal, geotechnical studies to quantify the identified shallow geohazards, and investigation of potential development options are underway. The appraisal area is located in the southeast portion of the Green Canyon Protraction Area on the outer continental shelf immediately north of the Sigsbee Escarpment. Water depths in this area
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
