RE:Lyle Stein on BNNAs it happens, I spoke with CPG IR just yeasterday about this very topic. They sell most of their oil at WTI price, but with a hedging programme.)Their oil is largely sold 'east' toward Chicago.
I was also told that much had been hedged at C mid $70's as reported in a recent news release for all to see. ( I could not find the details in a brief search)
