ABSTRACT: Sediments provide valuable information for geologists and geophysicists whenever they strive to understand, and reproduce, the geological evolution, lithology, rock properties, seismic response, and geohazards of a region. The analysis of sedimentary sequences is thus useful for the interpretation of depositional environments, sea-level change, climate change, and recognition of the sediments' source ...
Hydrocarbon discoveries in Equatorial Brazil, Equatorial Africa and French Guiana-Suriname-Guyana have recently confirmed their importance as new exploration frontiers. The Mundaú sub-basin, located on the Brazilian Equatorial Margin, comprises four producing fields in shallow waters: Xar´eu, Atum, Espada e Curim˜ a. In order to understand the structural and seismic-stratigraphic frameworks of an oil-producing ...
The Brazilian equatorial margin (BEM) evolved in response to transform motion between Brazil and Africa. In 2012, Petrobras drilled the Pecem well in the Mundaú subbasin (Ceará Basin) of the BEM to record the first deep-water oil discovery in the region. This work investigates the deep-water evolution of the Mundaú subbasin focusing on its structural and sedimentary evolution, and characterizes the petroleum sy...
Slope instability is one of the most effective processes shaping the sea floor of continental margins. The endproducts of slope instability, mass-transport deposits (MTDs), have been documented in the literature using diverse approaches. This paper tests a new methodology, applied to a region offshore Espírito Santo (SE Brazil), for the evaluation of MTDs' occurrence on continental slopes. A MTD inventory was, ...
