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 ...
In recent years, the Brazilian Equatorial Margin has drawn attention due to its similarity to areas with new hydrocarbon discoveries in the African conjugated margin, and in French Guiana. However, studies on the tectonic regimes associated with transform margins and their evolution, structures, and petroleum potential are still lacking due to the geological complexity of this region. To address this knowledge ...
On the basis of qualitative and quantitative geophysical interpretations, studies on tectonostratigraphic evolution were carried out in NW onshore Potiguar basin. Airborne magnetic and terrestrial gravity data were acquired in order to investigate tectonostratigraphic relationships in a poorly studied area of this oil-bearing Early Cretaceous basin. The present integrated study determined the main geophysical l...
The Cambro-Ordovician Jaibaras Rift is a NEeSW trending elongated feature, controlled by the Transbrasiliano lineament, locally known as Sobral-Pedro II shear zone (SPIISZ). An integrated study of geophysical data (gammaspectrometry, magnetometry and gravimetry) was undertaken in the Jaibaras Rift area, between Ceara Central (CCD) and M edio Coreaú domains (MCD), northwest Borborema Province. Geophysical data w...
An organic geochemical investigation combined with sequence stratigraphy was performed in the Ceara´ Basin, an offshore basin located in Northeastern Brazil. The information available from 30 well logs (gamma-ray, resistivity, density), besides geochemical (TOC, and pyrolysis indexes) and isotopic (δ13C) data, aided the preparation of a dataset for this study. The application of sequence-stratigraphic methods h...
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...
