If they were getting WTI for their oil I am sure it would be a different story; although NG down doesn't help either. Not saying PWT is highly favoured, but quoting WTI is as useful as quoting the price of corn in Turkey.
The good news is that Canadian Sweet has actually seen its differential decrease to $6 from over $9 and nothing like the differentials attached to Western Canada Select at $33. Penn Wests newer light oil is getting the Canadian sweet price.
But of course you know all that but wanted to do the WTI piece for bashing purposes.
