I think largely dependent on election outcome. If Romney wins, then pipelines get built as well as other things that I think will be favorable - favorable in my world meaning higher oil prices due to growing economy. Pipelines give Bakken producers more leverage than they currently have.
based on the higher gasoline yield, lower residue, Canadian pipeline construction, etc my WAG would be that $1 could be way low. I'd guess it could go for a 3 to 5% premium to WTI.
