I think this is pretty much what he said in his previous article on pricing going lower.

Basically saying future pricing will stable at ~$50, anything higher will create opportunity for US Shale Oil companies, anything lower they will not be able to sustain their own economies.

( I actually said something similar / if not the same and got downvoted >< )

Which got me to think, why aren't countries buying lots of cheap oil now and store them somewhere if they know prices will bounce back to $50+ in two years time? Or do setting up the infrastructure cost more then then $15 oil savings.
