Petrobras reported that drilling has been completed in well 4-SPS-86B (4-BRSA-971-SPS), located in block BM-S-8, in ultra-deep waters, in the pre-salt of Santos Basin. This is the third well drilled in the area of the Discovery Assessment Plan (PAD) of 1-BRSA-532A-SPS (Bem-te-vi).

The well, informally known as Carcara, is 144 miles (232 kilometers) off the coast and was drilled at a water depth of 6,650 feet (2,027 meters). Starting at 18,839 feet (5,742 meters) of drilling a significant column was detected containing, at least, 1,545 feet (471 meters) of excellent quality oil - 31 degree API and free of contaminants such as CO2 and H2S – with 1,319 feet (402 meters) in carbonate reservoirs of excellent porosity and permeability. Pressure data indicate that these reservoirs are interconnected.

Due to operational issues, it was not possible to reach the total depth, originally set for 22,966 feet (7,000 meters), and carry out complementary assessment work. Therefore, the well has been temporarily abandoned, which will allow the operation to be resumed in the future, if the consortium wishes to do so.
