My note on this is that as the industry shifts from light to heavy feedstocks, that is very bad news for propane customers. As I understand it, propane "is what it is", and there is no valve you can turn at the refinery that will change the percent that you can get out, so if there is less there to start with, less is what you will get. Thus, propane will get a double hit: first from declining petroleum production post peak, and second from the shift in that production from light to heavy crude.
