The auction of the Libra ultra-deep water oil field in the waters off Rio de Janeiro, Brazil. Shell, Total and two Chinese companies took part in the auction. Libra is estimated to hold about 12 billion barrels of oil and combined with the other fields in the newly discovered area has about 50 billion barrels of oil. Brazil's laws passed after the discoveries offshore were made in 2006 give Petrobras a critical role in development of the oil fields. A new company Petrasal was created to oversee the new oil fields. The winning bidder in this auction is required to pay the government $7 billion in an upfront payment and source much of the equipment inside Brazil. New investments are required in education, infrastructure and supporting public services after nationwide street protests, making oil field development and new revenues a priority for the government of Dilma Rousseff and the Workers Party that runs the government.
