Petrobras said an exploratory well north of Lula field in the Santos basin offshore Brazil has discovered good-quality oil in presalt carbonate reservoirs at 5,660 m based on wireline sampling.

The 1-RJS-689A (1-BRSA-925A RJS) well, also known as Dolomita Sul, is in 1,747 m of water on the BM-S-42 block 177 km south of Rio de Janeiro State. Petrobras is the block’s sole concessionaire.

Petrobras said the discovery “pushes the potential of the presalt region beyond the initial expectations” and that the well is still drilling toward other objectives.
