Offshore staff

RIO de JANEIRO -- Petróleo Brasileiro S.A. – Petrobras announces an oil discovery in the Campos basin pre-salt at well 6-AB-119D-RJS drilled in the Albacora field, 107 km (66.5 mi) off the coast and only 3.2 km (2 mi) from the drilling rig P-31.

Preliminary estimates indicate an economically recoverable volume potential of approximately 350 MMbbl of light oil.

Drilled at a water depth of 380 m (1,247 ft) it reached the total depth of 4,835 m (15,863 ft) where an oil column of 241 m (791 ft) was found, of which 104 m (342 ft) are from the carbonate reservoirs of the Macabu formation, with porosity around 10%.

Whether to conduct a long-duration test to investigate the production behavior of this new accumulation will be decided after the assessment of the cased-hole drillstem tests program.
