In 2006, the Persian Gulf countries (Bahrain, Iran, Iraq, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates) produced about 28 percent of the world's oil, while holding 55 percent (728 billion barrels) of the world's crude oil reserves. In 2006, the Persian Gulf countries combined exported 18.2 million barrels per day (bbl/d) including about 17 million bbl/d via the Strait of Hormuz representing roughly one-fifth of world oil supply. The group exported the remaining oil via pipelines through Turkey to the Mediterranean and Saudi Arabia to the Red Sea. OECD gross oil imports from Persian Gulf countries averaged about 10.4 million barrels per day (bbl/d) during 2006, accounting for 31 percent of the OECD's total net oil imports. U.S. gross oil imports from the Persian Gulf were 2.2 million bbl/d during 2006, accounting for 17 percent of the US total net oil imports. Besides oil, the Persian Gulf region also has sizeable reserves (2,509 trillion cubic feet -- Tcf) of natural gas, accounting for 41 percent of total proven world gas reserves.
