In the five-year period beginning in 2006 and ending in 2010, Iran has exported an average of $68 billion per year in crude oil. (The oil revenues peaked in 2008 at $87 billion). The 2010 oil revenues were at $72 billion.
During the same five-year period, the volume of imports into Iran has averaged $59 billion annually, or 87% of oil revenues.
Meanwhile, the volume of crude exported in 2010 dropped to 2.2 million barrels per day. As a result, Iran lost its long-held position as the second largest OPEC oil exporter to Nigeria. Iran is now OPEC’s third largest exporter.
