The reason for falling oil prices explained (maye)

IMO, oil and gas pricing is a bit more complex than some of the single-cause ideas expressed in this thread. No one has even touched on the difference in quality between different sources of crude. Also, when the majors are trading North Slope crude for Red Sea vouchers, it becomes ever more tricky to define dependence, import strategy, and such. I'm thinking that the quality of the Bakken oil is having a pretty big effect on refining and strategy in oil marketing.
