The U.S. Energy Information Administration (EIA) estimates that in 2013, Brazil was the eighth-largest energy consumer in the world and the third-largest in the Americas (North America, Central America, the Caribbean, and South America), behind the United States and Canada. Total primary energy consumption in Brazil has increased by more than one-third in the past decade because of sustained economic growth. The largest share of Brazil's total energy consumption is oil and other liquid fuels, followed by hydroelectricity and natural gas.
Preliminary statistics show Brazil was the 10th largest energy producer in the world in 2013. In addition, Brazil has increased its total energy production, particularly oil and ethanol. According to the Empresa de Pesquisa Energética (EPE), ethanol production represented 19% of Brazil's total energy production compared to 15% a decade ago. Oil remained at an average of 41% of total energy production as total energy production increased 36% in the past decade. Increasing domestic oil production has been a long-term goal of the Brazilian government, and recent discoveries of large offshore, pre-salt oil deposits could transform Brazil into one of the largest oil producers in the world.
Petroleum and other liquids
Brazil was the largest producer of petroleum and other liquids in South America in 2013.
Sector organization
State-controlled Petróleo Brasileiro S.A.(Petrobras) is the dominant participant in Brazil's oil sector, holding important positions in upstream, midstream, and downstream activities. The company held a monopoly on oil-related activities in Brazil until 1997, when the government opened the sector to competition. Royal Dutch Shell was the first foreign crude oil producer in the country, and it has been joined by Chevron, Repsol, BP, Anadarko, El Paso, Galp Energia, Statoil, BG Group, Sinopec, ONGC, TNK-BP, among others. Competition in the sector is not just from foreign companies. Brazilian oil company OGX, which is staffed largely with former Petrobras employees, started to produce oil in the Campos Basin in 2011.
The principal government agency charged with regulating and monitoring the oil sector is the the Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (ANP), which is responsible for issuing exploration and production licenses and ensuring compliance with relevant regulations. Recent legislation concerning pre-salt exploration and production has changed the operating environment somewhat. See the "Presalt Oil" section for a full discussion.
Reserves
EIA estimates that in January 1, 2014, Brazil had 13.2 billion barrels of proved oil reserves. According to Brazil's oil regulator the Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (ANP), Brazil had 15.6 billion barrels of proved oil reserves as of December 31, 2013, the second-largest level in South America after Venezuela. More than 94% of Brazil's reserves are located offshore, and 80% of all reserves are found offshore near the state of Rio de Janeiro. Offshore the state of Espirito Santo held the next largest accumulation at 9% of country's reserves.
