Brazil will be responsible for some of the world's largest increases in oil production in the coming decades. Advances in seismic imaging have enabled the discovery of offshore "pre-salt" deposits of oil in Brazil's Campos and Santos Basins (Figure 1). These pre-salt fields, so-called because they lie under massive layers of salt, are located 18,000 feet below the ocean floor under more than 6,000 feet of salt. Brazil already produces 2.1 million barrels per day (bbl/d) of crude oil and lease condensate, yet just became a net exporter in 2008. Pre-salt development, coupled with the ability to meet a large share of domestic demand with biofuels, is projected to transform the country into a major oil exporter.

The U.S. Energy Information Administration's International Energy Outlook 2011 (IEO2011) projects that the largest increases in conventional liquids production outside of the Organization of Petroleum Exporting Countries (OPEC) will occur in Brazil (Figure 2). Brazilian conventional production is projected to grow to 4.8 million bbl/d in 2035. This represents 40 percent of non-OPEC growth over the projection period and 14 percent of total world production growth in conventional liquids.
After 2015, the IEO2011 liquids supply projections are based on resource availability and the economic viability of production. While a massive resource base underlies EIA's projections of Brazilian production growth, the exact magnitude of the country's reserves is still unclear. According to Oil & Gas Journal, Brazil's proven oil reserves are currently estimated at 12.9 billion barrels, but this total does not include major pre-salt fields. Estimates of Brazil's pre-salt reserves have varied widely. In 2008, Haroldo Lima, Director General of Brazil's National Petroleum Agency, stated that the pre-salt could contain between 50 and 70 billion barrels of oil. In January 2011, Petrobras announced its assessment that the Lula and Cernambi fields contained 6.5 billion and 1.8 billion barrels of commercially recoverable oil, respectively. It will be some time before Brazil's pre-salt reserves are fully estimated. However, knowledge of precise reserve volumes is not critical to assessing the viability of Brazil's proposed expansion of production in the coming years.
Three major categories of challenges introduce uncertainty into estimates of Brazilian production growth: financial, operational, and legislative. The costs of Brazil's pre-salt development will be immense. In July 2011, Petrobras released its 2011-2015 business plan, which outlines a $224.7 billion investment program focused heavily on exploration and production. The plan calls for a reduction in downstream investment and divestiture of foreign assets to facilitate a sharpened domestic upstream focus. Notwithstanding Petrobras' 2010 share offering of $67 billion (the largest ever), the company will still need to maintain significant operating cash flow to achieve its goals.
