Petrobras Makes Discovery in Dolomita Sul Well

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

The new well, informally known as Dolomita Sul, is located at a water depth of 5,732 feet (1,747 meters) and is 110 miles (177 kilometers) off the coast of Rio de Janeiro State in Block BM-S-42. Petrobras is the sole concessionaire of this block.

This discovery confirms the potential of the pre-salt region beyond the limits of the first discoveries (pre-salt cluster).

The well, which is still in the drilling phase, also seeks to accomplish deeper objectives. After drilling is completed, Petrobras will evaluate the productivity of these reservoirs through formation tests.

The discovery was confirmed through oil sampling using cable test, at carbonate reservoirs in pre-salt layers, situated some 18,570 feet (5,660 meters) deep.
