Mapping of seismic and lithological facies is a very complex process, especially in regions with low resolution caused by extensive salt layers, even when only an exploratory view the distribution reservoir required. The aim this study was to apply multi-attribute analysis using unsupervised classification algorithm map carbonate presalt area located Outer high region Santos Basin. interval interest Barra Velha Formation, deposited during Aptian, which represents intercalation travertines,...
Presalt reservoirs of the Santos Basin accounted for more than 50% Brazilian hydrocarbon production in first two months 2019. Its most important are found Barra Velha Formation; thus understanding its genesis and geologic history is essential. This formation composed carbonates deposited an alkaline lacustrine environment with a multiplicity facies from boundstones grainstones to mudstones. We have performed sedimentary analysis based on integration sidewall core (SWC) samples well logs...
We present a multi-scale conceptual model based on structural controls of the migration mantle-derived CO 2 offshore in Santos Basin (Southeastern Brazil). assembled from regional 2D seismic reflection line integrated with potential gravimetric field data and local 3D volume well (lithologies situ stress). (i) The geochemical isotope range δ 13 C CO2 falls mostly within −7‰ −5‰ shows relatively high values for 3 He/ 4 He represented by an R/Ra rate up to 5.60, indicating mantle generation...

A Bacia de Itaboraí é considerada o primeiro segmento do Rifte Continental Sudeste Brasil a se abrir, durante Paleoceno. Há referências à existência calcretes na bacia, entretanto, até momento, não foram realizados estudos específicos sobre os e sua ocorrência, ainda há um número reduzido trabalhos envolvendo caracterização petrográfica dos depósitos sedimentares da bacia. Apresenta-se aqui uma caracterização, macromorfológica micromorfológica vadosos que constituem preenchimento inicial...
This paper presents an evaluation of a low-cost apparatus for Stepped-Frequency Continuous Wave (SFCW) radar-based Microwave Imaging (MWI) systems aimed at breast cancer detection. Software Defined Radio (SDR) is programmable device with the potential to circumvent Vector Network Analyzer usage realize MWI system, especially during prototyping stage, once more suitable system not established yet. BladeRF, SDR platform, coupled power amplifier and low noise amplifier, using two Vivaldi...
Topographic, gravimetric and magnetic data has been employed to map regional tectonic elements in the South Atlantic presenting major oceanic structures which had previously lacked continuity when approaching continental margin. The creation of such contoured maps proven that numerical transform methods involving regional/residual separation derivatives gravity magnetics can enhance geophysical signatures unveil hidden structures, especially transition from margins basin. In assessing trend...
Abstract The Itaboraí Basin, located in Rio de Janeiro state, is the smallest segment of Southeastern Brazil Continental Rift, and first to open, during Palaeocene. Numerous studies focused on its fossiliferous content, but few systematically approached depositional diagenetic processes products. A detailed description basal sedimentary deposits that remained after nearly fifty years exploitation for cement production allowed an interpretation initial tectono‐sedimentary conditions...
Diversas anomalias isoladas são observadas apartir de dados aeromagnetométricos na região da plataforma continental adjacente à Bacia Santos. Estas associadas a intrusões alcalinas por comparação com as corpos aflorantes conhecidos. Neste trabalho, é apresentado um estudo comparativo entre resposta magnética dos alcalinos ou subaflorantes conhecidos Arraial do Cabo (Cabo Frio, RJ) e uma notável anomalia que ocorre área submersa, próxima charneira cretácea Alicerçando este estudo, proposto o...
The Serra dos Tomazes, located in the Pirai District, RJ, consists of an intrusive alkaline body, composed mainly micronepheline-syenites. This body intrudes metatexites "Paraiba do Sul" folded belt. Mylonitic Zones we re recognized south and they may be associated with Alem Paraiba Lineament. lineament corresponds to ENE striking transcurrent fault. fault belongs a system faults that is called "São Paulo Transcurrence Zone". strike-slip form bulk "Sao Zone" are generally right-lateral....
Studies on evaporitic rocks are of great importance for the oil and gas industry as they can create traps seals hydrocarbon accumulations. Also, salt high ductility allows formation complex structures associated with halokinesis posing thus major challenges imaging at their flanks below structures. This paper discusses effects tectonics post-salt layers difficulties in interpreting top surface a particularly area Santos Basin. The available seismic migration velocity model data from an...
The Florianopolis Fracture Zone (FFZ), Brazil, delimits the Pelotas and Santos basins marks a major change in geology of continental margins from south to north, along both sides South Atlantic Ocean. prolongation it is represented by Lower Upper Cretaceous alkaline rocks, Paleocene hydrothermal manifestations river catchments. Geological review with total magnetic field reduced pole map (EMAG 2) were used investigate analyze Zone. Our results indicate that intra-continental NW-SE transfer...
