Ð?: The graph shows estimated oil production capacity for several Gulf countries between 1990 and 2010.
The bar chart illustrates the approximate capacity of oil production of six Gulf countries, from 1990 and 2010 . Each unit was measured in millions of barrels per day.
Overall, while Qatar witnessed nearly stability in the capacity of oil produced, there was an increase in those produced by four remaining countries. Especially, Saudi Arabia was the highest oil producing nation over the period.
A dramatically upward trend in the quantity of oil production was experienced in Saudi Arabia, while the opposite was true for Qatar over the span. In 1990, Saudi Arabia produced nearly nine million barrels of oil per day, after that Saudi Arabia’s figure surged to roughly 15 millions barrels of oil per day during the last year. Meanwhile, Qatar produced only approximately one million barrels of oil each day in 1990, and the figure for Qatar rose insignificantly in 2000 before declining back to one million barrels 11 years later.

Likewise, three remaining nations saw a similar gradual increase during the given period. Iran’s figure surged closely by two million barrels per day, starting at above three million barrels per day in 1990 and ending at almost five million barrels per day in 2010. Regarding Iraq, Kuwait and UAE, the quantity of oil can be produced in all three countries stood at around two million barrels per day in 1990 and rose by about two million barrels per day during the following 21 years
