Oil Production 1990-2010 statistics
The provided chart gives information concerning the production of oil in six different countries from 1990 to 2010.
We can see that the general trend for the production of oil was to increase over the period. For example, Saudi Arabia - the largest producer - saw a significant growth from just over 8 millions barrel per day in 1990 to around 15 millions barrel per day in 2010.
Other four countries (Iran, UAE, Iraq, and Kuwait) had a similiar trend where their oil production rose slightly and had reached roughly 4 millions barrels per day by 2010.
However, Qatar - the smallest producer - appeared not to follow this trend. It relatively remained stable over the period, accounting for 1 million barrels per day in the final period despite its slight increase in 2000.
Overall, all countries, except one witnessed an upward trend. Only in Qatar was the figure truly reversed.
