The Exploration and Discoveries of Oil Indications in the Santos Basin Conducted by Petrobras Are Significant Victories for the Brazilian Oil and Gas Sector.
Petrobras, a giant in the oil and gas sector, announced a significant discovery in the Santos Basin. The company informed the National Agency of Petroleum (ANP) about the identification of new oil indications at the well 3-BRSA-1388DA-SPS, located in block S-M-623, where the Sagittarius prospect is situated, as reported by Petronoticias. This news represents an important milestone for the energy industry and for Brazil as a whole.
New Perspectives in Oil Exploration in the Santos Basin
The first oil indications in the region of block S-M-623, in the pre-salt layer of the Santos Basin, date back to 2013, when Petrobras made significant discoveries through the pioneering well 1-BRSA-1063-SPS.
Subsequently, in January 2020, the company announced another discovery, this time in the first extension well of the block, 3-BRSA-1370-SPS.
