“…Its thickness decreases northwestward as a basement high. This present interpretation is well constrained by an extensive set of seismic lines described in many geophysical papers (Matos, 1992;Soares and Rossetti, 2005;Hoerlle et al, 2007). In addition, the comparison between the Euler solutions for the gravity data and the seismostratigraphic interpretation of the Potiguar Rift enabled us to identify similarities between the internal geometries of the rift obtained independently from both investigative methods.…”

“…In the study area, folds are relatively sub-parallel to faults, showing very acute angles. In addition, folds were mapped in other regions of the BEM such as in Barreirinhas and Pará-Maranhão basins by Azevedo (1991) and Sauerbronn (1996), in the Piauí-Camocim sub-basin by Zalán & Warme (1985), in Icaraí sub-basin by Castro (1993), in Potiguar Basin by Hoerlle et al (2007), in the Guyanas-Suriname basins by Goss et al (2008), Nemčok et al (2016a) and Loncke et al (2016) and in Equatorial Africa by Attoh et al (2004), Lamarche et al (1997) and Davison et al (2016).…”

Hydrocarbon discoveries in regions such as the Brazilian Equatorial Margin, Equatorial Africa and French Guiana have recently confirmed their importance as new exploration frontiers. The Mundaú sub-basin, located on the Brazilian Equatorial Margin, is an oil and gas producing region with four producing fields in shallow water: Xaréu, Atum, Espada e Curimã. In order to understand the structural and seismic-stratigraphic frameworks of an oilproducing area of the Brazilian Equatorial Margin, this work addresses the 3D geometry and 2 spatial distribution of main faults in the Curimã and Espada fields. The occurrence of hydrocarbons in the Mundaú sub-basin is compared with fields in other parts of the Brazilian Equatorial Basin, and in Equatorial Africa. Data from wells and a 3D post-stack timemigrated multichannel seismic volume are used to define nine (9) main seismic-stratigraphic units: the syn-rift Mundaú Formation (Units 1, 2, 3 and 4); the transitional Paracuru Formation (Unit 5) and the drift Ubarana (Uruburetama and Itapagé Members, Units 6 and 7), Tibau and Guamaré Formations (Units 8 and 9). The study area is dominated by NW-SE planar normal faults, basinward-dipping, that formed multiple half-grabens and tilted blocks with small anticlines and synclines genetically related to a transtensional system. Three types of plays are recognised in the Mundaú sub-basins: structural, combined (structural-stratigraphic) and stratigraphic (turbiditic). In the eastern part of the region where the basement is shallow, no oil was found. Conversely, oil was discovered in an anticlinal trap formed on a hanging-wall block analogous to fields in Côte D'Ivoire-Ghana transform margin. This work shows that combined traps on footwall blocks are successful plays near the shelf break of the Mundaú sub-basin, in similarity with the Espoir and Baobab fields in Ivory Coast Basin. Furthermore, turbiditic reservoirs in drift units are analogous to the Stabroek block in Guyana and prospects in the Gulf of Guinea. The structural and petroleum-play analyses in this work are therefore crucial to understand the multiple geological processes leading to the trapping of hydrocarbons in the larger Equatorial Atlantic Ocean.
