Tupi and Carioca -Brazil Part 2

Brazil's state-controlled Petroleo Brasileiro SA in November said the offshore Tupi field may hold 8 billion barrels of recoverable crude. Among discoveries in the past 30 years, only the 15-billion-barrel Kashagan field in Kazakhstan is larger.
Haroldo Lima, director of the country's oil agency, last week said another subsea field, Carioca, may have 33 billion barrels of oil. That would be the third biggest field in history, behind only the Ghawar field in Saudi Arabia and Burgan in Kuwait.
Carioca is one of seven fields identified so far in the BM- S-9 exploration area, part of a formation called Sugar Loaf.
If additional drilling by Petrobras, as Petroleo Brasileiro is known, confirms the Tupi and Carioca estimates, the fields together would contain enough oil to supply every refinery on the U.S. Gulf Coast for 15 years. Petrobras said it needs at least three months to determine how much crude Carioca may hold.
The U.S. imports about 10 million barrels of oil a day, or 66 percent of its needs, according to the Energy Department in Washington. Saudi Arabia was the second-largest supplier in January, behind Canada.
Persian Gulf nations accounted for 23 percent of U.S. imports, compared with Brazil's 1.7 percent share. Brazilian crude output rose 1.9 percent last year to 2.14 million barrels, according to the International Energy Agency.
