Enterprise Products Partners and Enbridge on Thursday announced a proposed new 800 kilometre (500 mile) pipeline from Cushing, Oklahoma – the pricing point for US crude – to the Gulf of Mexico. The Wrangler Pipeline would have the capacity to carry up to 800,000 barrels of crude oil a day. Although the glut at Cushing has eased this year it is the main factor behind US crude trading near a record discount of $25/barrel to the international Brent benchmark. Canadian heavy oil from the oil sands – all of which goes to the US – sells for $10+ less than US crude, meaning oil sands developers have to deal with an effective oil price of $60-$70 a barrel. Unlike the controversial Keystone XL, Wrangler does not cross international boundaries and won't have to be approved by US president Barack Obama.
