RIO DE JANEIRO -- Block BM-S-11, in ultradeep Santos basin waters, has proved the existence of yet another light oil field, with specific gravity around 30º API, in the pre-salt reservoirs, according to Petrobras.
Block BM-S-11 is composed of two exploratory areas. The first well, the 1-BRSA-369A-RJS (1-RJS-628A), was drilled in the larger one, informally called Tupi. The discovery was announced on July 11, 2006, and its assessment plan was approved by the NPA and is currently in execution.
The new discovery well, called 1-BRSA-618-RJS (1-RJS-656) and informally know as Iara, is located in the smaller area of the original block (green area in the map), and 2,230 m (7,316 ft) from the water line. The well is still being drilled in search of deeper prospects, the company says.
The discovery was proved by a light oil sampling collected via a cable test carried out in reservoirs at a depth of 5,600 m (18,372 ft).
After well completion, the consortium will proceed with the activities and make the investments that are required to verify both field dimensions and oil reservoir characteristics by forwarding an assessment plan to the NPA, as provided for in the concession agreement.
