In 2013, Brazil produced 2.0 million barrels per day (bbl/d) of crude oil and nearly one trillion cubic feet (Tcf) of gross natural gas. Within these figures, the share of production from presalt resources found under thick layers of salt thousands of feet below the ocean’s surface remains small but continues to increase. Crude oil production from the presalt layer was 15% of total production in 2013, a significant increase from 0.4% of total production in 2008 when oil from the presalt was first produced. Similarly, Brazil’s presalt natural gas production represents 14% of total production, up from 0.5% of total production in 2008. Exploration and development of Brazil’s presalt layer began in and around the Tupi field almost a decade ago, with first production in 2008. Further exploration showed hydrocarbon deposits in the presalt layer […]
