This is a list of countries by oil extraction (i.e., petroleum extraction or "production"), as compiled from the U.S. Energy Information Administration database for calendar year 2023, tabulating all countries on a comparable best-estimate basis.
Compared with shorter-term data, the full-year figures are less prone to distortion from periodic maintenance shutdowns and other seasonal cycles.
The 1979 oil crisis, sometimes referred to as the second oil crisis (in reference to the 1973 oil crisis), refers to the drop in oil production in the aftermath of the Iranian Revolution led to an energy crisis in 1979. Although the global oil supply only decreased by approximately four percent, the oil markets' reaction raised the price of crude oil drastically over the next 12 months, more than doubling it to $39.50 per barrel ($248/m). The sudden increase in price was connected with fuel shortages similar to the 1973 oil crisis.
In 1980, following the onset of the Iran–Iraq War, oil production in Iran fell drastically. Iraq's oil production also dropped significantly, triggering economic recessions worldwide. Oil prices did not return to pre-crisis levels until the mid-1980s.
