Paper Summary
The subsurface of the northern Pelotas Basin (aka “Pelotas Norte”) is considered under- explored. It is positioned in southern Brazil, south of the Santos Super-Basin. This region sits north of the Florianapolis Fracture Zone but south of the salt province to the north. Recent high-quality oil and gas discoveries on the conjugate Namibian margin have renewed interest in the region (Hedley et al., 2022). Recently acquired 3D data reveal intense early crustal deformation of the magmatic material making up the economic basement in the region. Here we assess the regional events leading to the emplacement of these structures. Additionally, we evaluate the hydrocarbon prospectivity of the overlying stratigraphic units using regional well data points and seismic facies.
