And it’s worth remembering why that happened– we didn’t have a choice. Global field production of crude oil (excluding natural gas liquids, which are not used as transportation fuel) stagnated at about 74 million barrels/day between 2005 and 2008. It is up a couple of million barrels since then, but more than 100% of this increase has been consumed by China alone, forcing the U.S. and other countries to reduce our oil consumption.

Throwing a little cold water on some recent, loudly reported unscientific predictions. When you read Hamilton, always be sure to read the comments by Jeffrey Brown for an important Big Picture view.
In addition to the uncertainties noted above about extrapolating historical production rates, the rate at which production declines from a given well over time is another big unknown. Another key point to recognize is the added cost of extracting oil from tight formations. West Texas Intermediate is currently around $85/barrel. With the huge discount for Canadian and north-central U.S. producers, that means that producers of North Dakota sweet are only offered $61 a barrel. Tight oil is not going to be the reason that we return to an era of cheap oil, for the simple reason that if oil again fell below $50/barrel, it wouldn’t be profitable to produce with these methods. Nor is tight oil likely to get the U.S. back to the levels of field production that we saw in 1970. But tight oil will likely provide a source of significant new production over the next decade as long as the price does not fall too much.
