Growing Glut

I am fascinated by the drop in oil prices.  No one predicted the price drop of the past six months.  No one knows if oil prices are going to $80 a barrel or $20 a barrel.  (There are guesses at both ends of the spectrum, so some analyst will be able to claim prescience.)  The attached Bloomberg article and the chart below are from last week but give an indication of where prices are likely to go, at least in the near term.
