ABSTRACT

Regional 2D seismic and well data were used to establish the general Previous HitsequenceNext Hit stratigraphic and structural Previous HitframeworkTop of the central Mississippi Canyon and northern Atwater Valley pro-traction areas, northern deep Gulf of Mexico. The continental slope consists of a complex allochthonous salt system including the Rum roho salt system, two isolated salt stocks, and the Sigsbee salt nappe. The depositional setting is characterized by three deep intra-slope minibasins and one suprasalt minibasin. The bulk of Oligocene-Pleistocene sediments that filled these mini-basins are primarily turbidites (sheet sands, channel-levee complexes, and overbank deposits) sourced from the Mississippi Delta system.
