Annual oil production by world region 1965-2022
Since the 1960s, the Middle East has been the global region that has produced the largest quantity of crude oil in most years, followed by North America, and then the Commonwealth of Independent States (most of the former-USSR). In the figures for annual output, there are notable fluctuations in output that coincide with major regional events, such as the Iranian Revolution in 1979, Soviet dissolution in 1991, or the boom in onshore shale oil drilling in the U.S. since 2010.
