The line graph illustrates the four
different country’s oil production ability from 2011 to 2015.
Overall it is clear that Saudi-Arabia was
the country that produced the most oil among four nations. It is also clear
that the amount of oil that Saudi-Arabia and Iran produced rose from 2011 to
2015, while Iraq and Kuwait declined over 4-year period.
In 2011, the amount of oil that
Saudi-Arabia and Iraq produced was almost same. Saudi-Arabia strengthen their
producing skills, so the amount of them increased steadily from 60 million of
barrels per week to 120 million of barrels per week. While, compared to
Saudi-Arabia, the ability of Iraq wasn’t well developed as much as Saudi-Arabia’s,
so the amount of them decreased gradually. As a result, the gap between
Saudi-Arabia become widen over 4-year period
In 2011, Kuwait produced 45 million of barrel per week and by following Iran produced about 10 million of barrel per week. In 2012, Kuwait’s amount was declining gradually and eventually reached about 20 million barrel in 2015. While, by the 2012, Iran’s amount was keep increasing from 10 million of barrel in 2011 to 110 million barrel in 2015. So Iran overtook the Kuwait and became the second most oil producing country among four counties.
