PETROBRS

abbreviation of Petrleo Brasileiro Sa, Brazilian company that was founded in 1953 as a government-owned monopoly to prospect, extract, and refine domestic petroleum and to transport that oil and its derivatives. Petrobrs is an operating company overseen by the National Petroleum Council (Conselho Nacional do Petrleo), a government agency established in 1938 to set national policies and control the overall development of Brazil's oil industry. Petrobrs is the largest corporation in both Brazil and South America. Its headquarters are in Rio de Janeiro. Petrobrs' rise to prominence was based on the growth of Brazil's crude-oil production from 2,700 barrels per day in 1953 to more than one million barrels per day in the late 1990s. The key to this growth was Petrobrs' discovery and subsequent exploitation of large deepwater oil fields in the Campos Basin, off the coast of Rio de Janeiro state, in the 1970s and '80s. These offshore fields now account for the majority of Petrobrs' oil production and the bulk of its proven reserves. Petrobrs was granted a monopoly over Brazil's imports of crude oil in 1963, and it took over Brazil's privately owned refineries after they were nationalized in 1964. Since the 1960s Petrobrs has also become a major producer of petrochemicals through its subsidiary Petrobrs Quimica (Petroquisa), a maker of plastics, rubber, and industrial chemicals from petroleum feedstocks. Among Petrobrs' other major subsidiaries are a fertilizer manufacturer and an export-import company. Although mainly devoted to developing petroleum sources in Brazil, on land and offshore, Petrobrs also has interests in oil fields in such areas as the Middle East, North Africa, and Colombia. In 1995, as part of a campaign to privatize state-owned industries, the Brazilian government passed a constitutional amendment ending Petrobrs' monopoly over the country's oil and natural-gas industries. These were opened to foreign competition for the first time, allowing Petrobrs to enter joint ventures with foreign companies to prospect, extract, refine, and distribute oil and natural-gas products in Brazil.
