Exports
According to International Energy Agency’s Monthly Oil Data Service and Global Trade Atlas, Iran’s net crude and product exports in 2006 averaged 2.5 million bbl/d, primarily to Japan, China, India, South Korea, Italy, and other Organization for Economic Co-operation and Development (OECD) nations, making it the fourth-largest exporter of crude oil in the world. In 2006, Iran’s oil export revenues amounted to $54 billion.
