Data for the below chart is from the Weekly Petroleum Status Report.
Here we have a three year WTI price comparison chart. You can see that the 2014 price collapse began at almost the exact same time of the year as the 2008 price collapse. The 2008 collapse was a lot more dramatic and fell faster and slightly lower than the 2014 collapse. The 2008 collapse bottomed out around Christmas of that year and the 2014 did not pause until late January 2015. However by late October 2009 the WTI price was already in the $80 range. This time however we are still stuck below $50.
