Petrobras announces the discovery of a new good-quality oil accumulation at well 1-RJS-689A (1-BRSA-925A RJS), to the north of Lula field, in the Santos Basin pre-salt cluster.

The new well, known as Dolomita Sul, is located at a water depth of 1,747 meters and is 177 km off the coast of Rio de Janeiro State (Block BM-S-42). Petrobras is the sole concession holder of this block.

This discovery pushes the potential of the pre-salt region beyond the initial expectations.

The well, still in the drilling phase, also has more ambitious objectives. After drilling is completed, Petrobras will evaluate the productivity of these reservoirs using formation tests.

The discovery was initially confirmed by cable test oil sampling, in pre-salt carbonate reservoirs, at around 5,660 meters deep.
