What is the delta between oil sands production and, for instance, U.S. shale energy production and Saudi production. It strikes me that this is an important question, because if the Saudis are pursuing a low price agenda to try to squeeze out shale gas production in the U.S., the delta between oil sands production in Canada and shale gas production and their production is an important one for us to be cognizant of. What is the delta between these modes of production?
