The Brazilian North and Northeast Basins could be the country’s new great oil frontier

(TN) The basins of the North and Northeast of Brazil may be the new great frontiers of the country’s oil. WesternGeco has announced a new “Reimaging” project of 60,000 kilometers of high resolution 2D data in the Brazilian Equatorial Margin, covering the Foz do Amazonas, Pará-Maranhão, Barreirinhas and Ceará basins. The project will apply advanced imaging technologies to better define complex structures in the region, which is considered one of the last opportunities to explore new frontiers. Hence, the importance of applying new technologies to obtain high definition data and offering companies a better investment assessment during the exploration phase. The sedimentary basins of Northeast Brazil present geological formations similar to those found in Guyana and Suriname, where, in recent years, several important hydrocarbon discoveries were made, in addition to being analogous to the basins of the African Conjugate Margin.

WesternGeco’s solution will allow energy companies to gain a better understanding of the region’s complex geology, reducing exploration uncertainties in the 289 blocks made available by the ANP for the Permanent Concession Offer (PCO). The “Broadband” reprocessing stream uses the latest in seismic data processing algorithms, including noise and multiple attenuation, real amplitude preserved, tomography and “pseudo-3D” velocity field, creating a consistent velocity model across the rim. WesternGeco will provide Kirchhoff TTI Migration in depth, including (Gathers) partial stacks (Full, Near, Mid & Far) and consistent velocity field.

According to Fernando Alvarez, WesternGeco Exploration Data Manager – Brazil, the project represents confidence in Brazil’s potential for exploring new fields: “We are very excited, we use the best algorithms and processing experts from WesternGeco to provide a solution as precise as possible in the exploration of an important border margin”.
