The world is awash in oil, I'm hearing. The problem is, it's fairly expensive oil.
Take for example Canada. The country has managed to increase its production of oil by a million barrels a day over the last decade. But almost all of that increase has come from oil sands. If you consider only conventional crude oil, Canadian production today would be a third of a million barrels a day lower than at its peak in 1973.

Even without counting environmental costs, that stuff's not cheap. It was profitable when West Texas Intermediate was over $90. But last week WTI closed at $66. Here are some of the estimates from the Wall Street Journal:
The break-even price for new oil-sands surface mines is among the most expensive in the world, at around $85 a barrel, according to Bank of Nova Scotia . Operating costs at existing mines are less than half that amount. But the break-even point for so-called in situ projects, in which bitumen is heated and pumped up to the surface, range between $40 a barrel and $80 a barrel. Such projects represent the majority of future growth.
Or consider the United States, where production has grown 2 mb/d since 2004. More than 3 mb/d of that growth has come from fracking of oil trapped in tight geologic formations. Without tight oil, u.s. production would be down more than a million barrels a day over the last ten years and down 5-1/2 mb/d from its peak in 1970.

Estimates again vary, but prices this low have to severely inhibit new investment in U.S. tight oil. Without continuing new drilling, U.S, tight oil production would quickly fall. And the economics of deep ocean drilling, which has also been important in supporting production in the U.S. and around the world, have become even more difficult at today's low prices.
