While I am not an expert in the oil industry, I found the above comments quite fascinating; they're spurring me to do a bit of my own research, in fact. I don't know who is right, but I just have to ask: "You obviously have absolutely no clue about what you are talking about." Would you say that to someone in person, too? The Internet is a good place to keep as much civility as possible, since there's so little of it to go around.
