RIO DE JANEIRO – Petrobras has completed drilling one more well in the Santos basin presalt Franco area. Referred to as 3-BRSA-1184-RJS (3-RJS-723), and informally known as Franco Leste, the well is in a water depth of 2,011 m (6,598 ft), some 200 km (124 mi) from the city of Rio de Janeiro and 7.5 km (5 mi) southeast of discovery well 2-ANP-1-RJS (Franco).
The well has confirmed the discovery of good-quality oil (28º API) in carbonate reservoirs below the salt layer starting at a depth of 5,398 m (17,710 ft). The TD of 5,900 m (19,357 ft) was reached after a 396-m (1,299-ft) column of oil was confirmed. Reservoir samples, of thicknesses similar to the discovery well, confirm the extension of these oil reservoirs for the eastern portion of Franco block, says Petrobras.
Petrobras has acquired the right to produce up to 3.058 Bboe in Franco. This exploratory phase is expected to be concluded by September 2014.
