In Canada right now, we upgrade about 60% of the bitumen into light oil. In that 60% right now, just about half and half are using a combination of both coking on one side and hydrogen addition on the other side. In fact, some facilities use both. Remember, the hydrogen addition takes the hydrogen out of the natural gas and has some CO2 impacts as well.
