OPEC stands for Organization of Petroleum Exporting Countries. In September 1960, four Persian Gulf nations (Iran, Iraq, Kuwait, and Saudi Arabia) and Venezuela formed OPEC in order to obtain higher prices for crude oil. By 1973, eight other nations (Algeria, Ecuador, Gabon, Indonesia, Libya, Nigeria, Qatar, and the United Arab Emirates) had joined OPEC; Ecuador withdrew at the end of 1992, and Gabon withdrew in 1994.
