Tar sands, oil shale, and heavy oil: Why the conventional wisdom about unconventional oil is likely to be wrong
In the old days, that is before 2010, the oil industry used to regale the public with tales of plenty that revolved around what is commonly called "conventional oil." Then in its 2010 World Energy Outlook, the International Energy Agency announced that the peak in the rate of production of conventional oil had already arrived, probably in 2006. The agency projected that production of so-called "unconventional oil" would grow considerably over the coming decades and allow total oil production to rise. But, new unconventional oil production may not be able to make up for the decline in the rate of conventional oil production. And, rate is the key metric.
