Here's a look at crude oil reserves and production around the world.
Facts: Crude oil is a form of liquid petroleum, extracted from rock formations and used for fuel and other purposes.
Members of the Organization of the Petroleum Exporting Countries (OPEC) produce 42.8% of the world's crude oil, and possess more than 81% of the world's total proven crude oil reserves.
The 12 countries/members of OPEC: Algeria, Angola, Ecuador, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, and Venezuela.
The following countries have the world's largest reserves of crude oil, according to OPEC. (as of 2011)

-- Saudi Arabia - 265,405 billion barrels
-- Iran - 154,580 billion barrels
-- Iraq - 141,350 billion barrels
