Brazilian state oil company Petrobras has announced that the second well drilled in the area known as Tupi Northeast, in the Santos Basin Pre-Salt Region, has confirmed the discovery of good quality oil.
The well, named 1-BRSA-976-RJS (1-RJS-691), is located north-east of the Lula field, at a water depth of 2,131 metres, and 255 kilometres off the coast of the city of Rio de Janeiro. The first well drilled was 3-BRSA-944-RJS (3-RJS-688A), in the Franco area. The discovery was confirmed by means of 26o API oil samples, obtained by cable tests, collected from 4,960 metres. So far, an oil column with over 290 metres in thickness has been identified in the pre-salt carbonate reservoirs.
The well is being cased in the reservoirs' intervals. The continued drilling of this well aims to investigate the final depth of such reservoirs, as well as to verify the oil/water contact. Once drilling is completed, a Formation Test is scheduled to be performed to assess the productivity of the oil reservoirs.
