Historical oil prices per barrel

                      Without oil supply disruptions, falling demand corresponds to falling prices.

Sample Answer:
The given graph illustrates fluctuation of the price of oil per Barrel from 1973 to 2009. The data sources are and the Revenue department of Alaska.

It is clear from the graph that the oil price fluctuated between 1973 and 2003 and reached a peak of approximately 145 USD per Barrel after 2006. From 1973 to 1980, the oil price increased significantly from 5 to 40 USD per Barrel. However, without a reason, the price went down to about 15 USD per Barrel in 1986 and continued to fluctuate until 2003.

After 10 years of the fluctuation, interestingly enough, the price went up dramatically to as much as 60 USD per Barrel in 2007 and rocketed to roughly 142 USD, which was a peak, in around 2008 and decreased dramatically to 40 USD per Barrel in 2009.

Without the supply disruption, it is predicted that the oil price will be falling down as the demand decreases.
