Could Petrobras be producing oil on a middle eastern scale?

Yesterday, the head of National Petroleum Agency Haroldo Lima made a statement regarding a potential oil find near Carioca field. He estimates that the area could potentially have reserves somewhere near the 33 billion barrels. If confirmed, the new deep-water sub-salt field off the coast of Sao Paulo state would be the largest find in the world in the past 30 years. The stock reacted, skyrocketing ~8%. Petrobras is my largest holding and I was happy to see any appreciation in this stock. This find if confirmed dwarfs the last time PetroBras discovered in Tupi. However, this news was widely known and many had widely speculated that huge amounts of oil in near the Caroica field existed. Is the market late to the game? Who knows. I do know that the managment at Petrobras is extremely conservative. When this is confirmed, it definitely puts Brazilians state owned Petrobras on the top 10 oil producing countries. Brazil to join OPEC ??? :)
