Seismic survey specialist Spectrum has begun a 10,000 square kilometer 3D multi-client seismic project over the Southern Santos Basin in Brazil.Illustration; Praia do Arpoador, Rio de Janeiro; Photo by: Shot by Cerqueira on UnsplashSpectrum said on Monday that the survey covered an area south of the major oil and gas discoveries in the Santos Basin and the recent highly sought after blocks offered in Rounds 2, 3, 4, and 15.The company added that fast-track data would be available for the round expected in the second half of 2019.The 3D project builds on Spectrum’s 2D database in the region and marks the opening of the highly prospective deepwater area in the Santos basin.Rune Eng, CEO of Spectrum, said: “Spectrum has acquired 200,000 kilometers of long offset high quality 2D data covering almost the complete coastline of Brazil. We are now moving to the next growth stage in Brazil, using our 2D to locate prospective areas for 3D acquisition.“This project builds on Spectrum’s strategy of creating a complete and comprehensive database in Brazil. Our seismic database empowers the oil and gas industry to evaluate blocks in one of the most popular basins in the world and helps the government to select blocks for future license rounds.”It is worth reminding that Spectrum in April began the acquisition of offshore multi-client 2D seismic data over another offshore are in Brazil, the Pernambuco-Paraiba basins. These are located along the Eastern Margins of Brazil. The survey covers an area north of the prolific Sergipe Basin that would be included in Round 16 scheduled for 2019.
