33 billion barrels
This still hasn't been confirmed by Petrobras, but the head of the Brazilian National Petroleum Agency has announced it.
And we're still waiting to hear about the Sugar Loaf field! However, I read something which said Petrobras is trying to figure out whether this Carioca field and Sugar Loaf are two separate fields, or one large, connected one, so this figure may or may not include both.

A deep-water exploration area off Brazil's coast could contain as much as 33 billion barrels of oil, the head of Brazil's National Petroleum Agency said Monday. That would make it the world's third-largest known oil reserve.
Haroldo Lima cautioned that his information on the field off the coast of Rio de Janeiro is unofficial and needs to be confirmed.
The state-run Petrobras oil company declined comment on what would be the planet's largest oil find in decades, and its shares moved wildly in positive territory after Lima made the comments.
