If saudi arabia is hit with massive coordinated terror attacks, then it could easily go to $80-100... and even wores, if someone finds out that oil is not an unlimited resource, then $150-XXX.
* disclaimer - yes, I´m a pessimist looking at the oil prices, but that is probably because I want the western world to speed up the change from oil to renewable energy, and the sooner prices rise, the more time we will have to make the change...
