Petrobras today announced that it has identified the presence of good quality oil in well 4-SPS-91 (4-BRSA-1002-SPS), in shallow waters of south Santos Basin, in an area known as Tiro and Sidon, offshore Brazil.
The new well, informally known as Patola, is located at a water depth of 299 meters, some 200 km off the coast of São Paulo State and 3.8 km from discovery well 1-SPS-57 (1-BRSA-658-SPS), in the Evaluation Plan area containing wells 1-SPS-56 and 1-SPS-57 (1-BRSA-607 / 1-BRSA-658), former block BM-S-40.
Preliminary analyses indicate that this oil is of the same quality as the oil found in wild cat wells, around 36o API.
The discovery was confirmed by cable test oil samples taken from the post-salt sandstone. The reservoir is approximately 2,160 meters deep.
Petrobras said it would proceed with the activities and investments set forth in the Evaluation Plan, including drilling other wells in the area, and would goa ahead with an Extended Well Test (EWT). EWTs are currently in progress on wells 1-SPS-56 and 1-SPS-57.
