these are particularly timely http://www.rbnenergy.com/the-bakken-buck-starts-here-crude-pricing-part-1 http://www.rbnenergy.com/the-bakken-buck-starts-here-crude-pricing-part-II this might also be useful and they they think Bakken crude should trade at $0.50 to $1.00 premium to WTI. http://www.turnermason.com/Publications/petroleum-publications_assets/Bakken-Crude.pdf 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. As of 1 week ago Bakken was trading at $11.65 discount to WTI http://www.reuters.com/article/2012/06/05/markets-usa-cash-crude-idUSL1E8H5DK320120605 but then you have the wacko crowd that just doesn't understand numbers http://www.desmogblog.com/new-bakken-shale-pipeline-cushing-ok-works
