The table below shows the estimated oil capacity of six countries
The bar chart compares the daily oil production capacities of six nations (Saudi Arabia, Iran, Iraq, Kuwait, the UAE, and Qatar) over two decades from 1990 to 2010, measured in millions of barrels.
Overall, Saudi Arabia dominated production throughout the period, while Qatar consistently remained the lowest producer. Most countries demonstrated gradual increases in output, with fluctuations in some years.
Saudi Arabia’s production grew most dramatically, surging from approximately 8 million barrels per day in 1990 to over 14 million by 2010 – nearly doubling its output. In stark contrast, Qatar’s production never exceeded 1 million barrels daily, despite a minor rise in 2000.
The remaining four countries showed similar patterns of moderate growth. Iran began as the second-largest producer (3 million barrels) and maintained this position, reaching just over 4 million barrels by 2010. Iraq, Kuwait, and the UAE started at around 2 million barrels each in 1990. While the UAE experienced a temporary plateau in 2000, all three nations eventually reached nearly 4 million barrels daily by 2010.
Notably, production trends were generally upward across all countries except for Qatar, which stabilized after 2000, and the UAE’s brief stagnation at the turn of the century.
