Export Sales Volumes and Prices
While our principal market is the Brazilian market, as our domestic production of crude oil has increased, we have begun to export greater amounts of crude oil and oil products that exceed Brazilian demand. We also export volumes of domestically produced heavy crude oil that our refineries are unable to process operationally or economically. See Item 4. Information on the CompanyRefining, Transportation and Marketing. Our export volumes of crude oil and oil products totaled 186,221 million barrels of crude oil equivalent in 2004, as compared to
192,545 million barrels of crude oil equivalent in 2003 and 202,003 million barrels of crude oil equivalent in 2002. We base our crude oil export prices on international prices, as adjusted to reflect specific market conditions. We determine export prices of our oil products and natural gas by reference to market conditions, as well as direct negotiations with our clients. As a result of an increase in average prices for export sales of crude oil and oil products, partially offset by a decrease in the volume of exports, the total value of our crude oil and oil product exports (measured on a free-on-board basis) in 2004 was U.S. $5,923 million, as compared to U.S.$5,335 million in 2003 and U.S.$4,610 million in 2002, representing approximately 15.8% of our net operating revenues in 2004, as compared to 17.3% in 2003 and 19.9% in 2002.
