11-08-09 Brazilian state-run energy giant Petrobras notified the country's National Petroleum Agency that it found traces of oil in a wildcat well in the Santos Basin.
The find was made at the offshore BS-500 block in the Santos Basin, off the coast of Rio de Janeiro and Sao Paulo states.

The Peregrine 1 rig spudded the 5BRSA744RJS well at the BS-500 block, drilling to a total depth of 4,163 metres, according to ANP drilling data. The Pirapitanga, Tambuata and Carapia fields in the BS-500 block were declared commercial finds in December 2006, according to the agency.
Oil companies operating in Brazil must inform the ANP of indications of oil, gas or hydrocarbons in any exploratory well within 48 hours. The disclosures are routine and don't indicate commercial viability.
