Following my previous article — Peak Demand? No, A New Gasoline Demand Record— I received some interesting feedback from readers. It quickly became apparent that some didn’t understand that the current discussions around “peak oil demand” are quite different than the “peak oil” arguments that were popular a few years ago.

Some interpreted my headline to mean that peak oil is a myth and that oil supplies will simply continue to grow. Actually, I was addressing the irrational exuberance around the near-term peak oil demand argument, which is something entirely different.

So let’s review.

Almost from the beginning of the U.S. oil industry, there have been those who suggested that it wouldn’t be long before oil production began to inevitably decline. The layman’s understanding of “peak oil” typically boiled down to “The world is running out of oil.”

But that was a misunderstanding of the actual peak oil argument. It wasn’t that the world was going to run out of oil, it was that oil production would begin a long decline and cause havoc in a world that is still highly dependent upon oil. A decade ago many prognosticators made dire predictions of the consequences of peak oil, pointing to events like the 1973 OPEC oil embargo or highlighting the fallout whenever oil shortages took place in an area.

Simply put, modern civilization can’t function without oil, so peak oil necessarily meant dire consequences. Books were written on the concept. In 2005 the late Matt Simmons published Twilight in the Desert, in which he argued that oil production in Saudi Arabia was nearing terminal decline.

For a while, it looked like Simmons could be right. Production in Saudi Arabia remained flat, global demand continued to grow, and oil prices skyrocketed above $100 a barrel (bbl). These were just the types of consequences predicted by the peak oil camp.

Fast forward a few years, and after falling for nearly 40 years, U.S. oil production began to surge as a result of the marriage between hydraulic fracturing and horizontal drilling. It turns out that high prices can indeed enable a lot of new oil production, which was perhaps the biggest blind spot among the near-term peak oil adherents.
