The northern Gulf of Mexico (GOM) features all necessary elements for the formation and preservation of subsurface gas hydrates, including a prolific petroleum system, a variety of structural and stratigraphic migration pathways that focus hydrocarbon migration into the shallow sediments, variable geothermal gradients that support a locally thick gas hydrate stability zone, and silt- and sand-rich depositional systems both on the shelf and in the deep basin that provide potential host reservoirs. Consequently, gas hydrates have been a focus of study in the GOM since the early 1980s. Initial work detailed the occurrences of massive seafloor gas hydrate “mounds” and...
