I get what you mean. That will really depend on where you get the oil from. Some places need a lot more downstream processing (looking at alberta oil sands) to get something useable than others (the middle east). Whether you want to consider that analogous to the electrolysis step or to another one is not clear since the processes don't map one to one.
