For more discussion, there is also a thread on theoildrum and interesting graphs by Oil CEO.

"Oil prices have risen more than 20 percent since mid-February, despite sizable U.S. crude inventories, as geo-political fears compounded fundamental worries that refiners might struggle to make enough gasoline for the summer driving season."
"A critical point to keep in mind is that an exporter can only export what is left after domestic consumption is satisfied. Consider a simple example, a country producing 2.0 mbpd, consuming 1.0 mbpd and therefore exporting 1.0 mbpd. Let's assume a 25% drop in production over a six year period (which we have seen in the North Sea, which by the way peaked at 52% of Qt) and let's assume a 10% increase in domestic consumption. Production would be 1.5 mbpd. Consumption would be 1.1 mbpd. Net exports would be production (1.5 mbpd) less consumption (1.1 mbpd) = 0.4 mbpd. Therefore, because of a 25% drop in production and because of a 10% increase in domestic consumption, net oil exports from our hypothetical net exporter dropped by 60%, from 1.0 mbpd to 0.4 mbpd, over a six year period.
" We are deeply concerned that the world is probably facing an imminent and catastrophic collapse in net oil export capacity because of declining production and increasing domestic consumption in the top exporting countries.
"Fifty years ago this week, on March 8, 1956, at a meeting of the American Petroleum Institute in San Antonio, Texas, M. King Hubbert, in the preprinted version of his prepared remarks, had the following statement, "According to the best currently available information, the production of petroleum and natural gas on a world scale will probably pass its climax within the order of a half century (i.e., by 2006), while for both the United States and for Texas, the peaks of production may be expected to occur with the next 10 or 15 years (i.e., 1966 to 1971)." As more and more people are learning, Lower 48 oil production, as predicted by Dr. Hubbert, peaked in 1970, and it has fallen fairly steadily since 1970.
Kenneth Deffeyes, in Chapter Three of his recent book, "Beyond Oil: The View From Hubbert's Peak," described a simplified way of predicting the production peaks for various regions and for their subsequent declines. One simply plots annual production (P) divided by cumulative production to date (Q) on the vertical axis, or P/Q, versus Q on the horizontal axis. Stuart Staniford, on The Oil Drum Blog, has described this technique as "Hubbert Linearization" or HL.
With time, a HL data set starts to show a linear progression, and one can extrapolate the data down to where P is effectively zero, which gives one Qt, or ultimate recoverable reserves for the region. Based on the assumption that production tends to peak at about 50% of Qt, one can generate a predicted production profile for the region. The Lower 48 peaked at 48.5% of Qt.
Using the HL technique, Dr. Deffeyes, an associate of Dr. Hubbert, predicted that the world crossed the mathematical 50% of Qt mark on December 16, 2005. In other words, Dr. Deffeyes believes that the world is now where the Lower 48 was at in the early Seventies."
