There Will Be Oil

For decades, advocates of 'peak oil' have been predicting a crisis in energy supplies. They've been wrong at every turn, saysDaniel Yergin.

Since the beginning of the 21st century, a fear has come to pervade the prospects for oil, fueling anxieties about the stability of global energy supplies. It has been stoked by rising prices and growing demand, especially as the people of China and other emerging economies have taken to the road.

This specter goes by the name of "peak oil."

Its advocates argue that the world is fast approaching (or has already reached) a point of maximum oil output. They warn that "an unprecedented crisis is just over the horizon." The result, it is said, will be "chaos," to say nothing of "war, starvation, economic recession, possibly even the extinction of homo sapiens."

Pulitzer Prize-winning author Dan Yergin says the global supply of oil and gas has risen in the last 20 years, defying the predictions of "peak oil" theorists. In the Big Interview with WSJ's David Wessel, he looks at the world's energy future.

The date of the predicted peak has moved over the years. It was once supposed to arrive by Thanksgiving 2005. Then the "unbridgeable supply demand gap" was expected "after 2007." Then it was to arrive in 2011. Now "there is a significant risk of a peak before 2020."

But there is another way to visualize the future availability of oil: as a "plateau."

In this view, the world has decades of further growth in production before flattening out into a plateau—perhaps sometime around midcentury—at which time a more gradual decline will begin. And that decline may well come not from a scarcity of resources but from greater efficiency, which will slacken global demand.


Those sounding the alarm over oil argue that about half the world's oil resources already have been produced and that the point of decline is nearing. "It's quite a simple theory and one that any beer-drinker understands," said the geologist Colin Campbell, one of the leaders of the movement. "The glass starts full and ends empty, and the faster you drink it, the quicker it's gone."

Marion King Hubbert was one of the most eminent—and controversial—earth scientists of his time. Born on a ranch in San Saba, Texas in 1903, he did his university education, including his Ph.D., at the University of Chicago. One of his fundamental objectives was to move geology from what he called its "natural history phase" into its "physical science phase," firmly based in physics, chemistry and, in particular, rigorous mathematics.

In the 1930s, while teaching at Columbia University, Hubbert became active in a movement called Technocracy and served as its educational director. Holding politicians and economists responsible for the debacle of the Great Depression, Technocracy promoted the idea that democracy was a sham and that scientists and engineers should take overthe reins of government and impose rationality on the economy. "I had a boxseat at the Depression," Hubbert later said. "We had manpower and raw materials. Yet we shut the country down."

Technocracy envisioned a no-growth society and the elimination of the price system, to be replaced by the wise administration of the Technocrats. Hubbert believed that a "pecuniary" system, guided by the "hieroglyphics" of economists, was the road to ruin.

In the late 1940s, Hubbert heard another geologist say that 500 years of oil supply remained in the ground. This couldn't possibly be true, he thought. He started doing his own analysis. In 1956, he unveiled the theory that would forever be linked to his name. He declared that U.S. oil production would hit its peak somewhere between 1965 and 1970.

For many decades, the U.S. had been, by far, the world's largest oil producer. All through the 1960s, domestic production had supplied 90% of demand. No longer. To meet its own growing needs, the U.S. became a major importer, deeply enmeshed in the world oil market and a new set of geopolitical concerns.

Hubbert was very pessimistic about future supply. He warned that the era of oil would be only a brief blip in mankind's history. In 1978, he predicted that children born in 1965 would see all of the world's oil used up in their lifetimes. Humanity, he said, was about to embark upon "a period of non-growth."


Hubbert's original projection for U.S. production was bold and, at least superficially, accurate. His modern-day adherents insist that U.S. output has "continued to follow Hubbert's curve with only minor deviations."

But it all comes down to how one defines "minor." Hubbert got the date exactly right, but his projection on supply was far off. He greatly underestimated the amount of oil that would be found—and produced— in the U.S.

By 2010, U.S. oil production was 3½ times higher than Hubbert had estimated: 5.5 million barrels per day versus Hubbert's 1971 estimate of no more than 1.5 million barrels per day. Hardly a "minor deviation."

The modern oil industry was born when "Colonel" Edwin Drake struck oil near the small timber town of Titusville in northwest Pennsylvania. Other production centers arose during this era in the Russian Empire and around Baku, on the Caspian Sea. But Pennsylvania was the Saudi Arabia of its day.

World War I was the first mechanized war, complete with tanks and airplanes. As oil went to Europe to ensure the mobility of Allied forces, 1918 saw the highest gasoline prices (adjusted for inflation) ever recorded in the U.S. "Gasolineless Sundays" were instituted to encourage people to drive less.

In October 1973, Arab countries launched an attack on Israel, initiating the Yom Kippur War. In response to U.S. resupply of armaments to Israel, Arab exporters embargoed oil shipments. Within months, petroleum prices quadrupled. Fear of a permanent shortage spurred oil development in Alaska and the North Sea.

"Hubbert was imaginative and innovative," recalled Peter Rose, who was Hubbert's boss at the U.S. Geological Survey. But he had "no concept of technological change, economics or how new resource plays evolve. It was a very static view of the world." Hubbert also assumed that there could be an accurate estimate of ultimately recoverable resources, when in fact it is a constantly moving target.


The idea of "proved reserves" of oil isn't just a physical concept, accounting for a fixed amount in the "storehouse." It's also an economic concept: how much can be recovered at prevailing prices. And it's a technological concept, because advances in technology take resources that were not physically accessible and turn them into recoverable reserves.




As proof for peak oil, its advocates argue that the discovery rate for new oil fields is declining. But this obscures a crucial point: Most of the world's supply is the result not of discoveries but of additions and extensions in existing fields.



Based on current and prospective plans, it appears that the world's production capacity for "oil and related liquids" (in industry jargon) should grow from about 92 million barrels per day in 2010 to over 110 million by 2030. That is an increase of about 20%.

But this is no done deal. There are many "buts," having to do with what happens above ground. The policies of governments around the world—especially concerning taxes and access to resources—have a major impact on whether and when oil is discovered and developed.

Wars and civil wars, social turmoil and political upheavals, regional conflict, corruption and crime, mismanagement of resources—all of these can affect not only current production but also investment and future prospects. Environmental and climate policies can alter the timing and scale of development, as can geopolitics and politics within oil-producing countries.

In short, in a world whose $65 trillion economy depends greatly on oil, energy security will be a lasting and critical preoccupation.

Meeting future demand will require innovation, investment and the development of more challenging resources. A major reason for continuing growth in petroleum supplies is that oil previously regarded as inaccessible or uneconomical is now part of the mix, such as the "presalt" resources off the coast of Brazil, the vast oil sands of Canada, and the oil locked in shale and other rocks in the U.S.

In 2003, the Bakken formation in North Dakota was producing a mere 10,000 barrels a day. Today, it is over 400,000 barrels, and North Dakota has become the fourth-largest oil-producing state in the country. Such "tight" oil could add as much as two million barrels a day to U.S. oil production after 2020—something that would not have been in any forecast five years ago.

Overall U.S. oil production has increased more than 10% since 2008. Net oil imports reached a high point of 60% in 2005, but today, thanks to increased production and greater energy efficiency (plus the use of ethanol), imports are down to 47%.

Things don't stand still in the energy industry. With the passage of time, unconventional sources of oil, in all their variety, become a familiar part of the world's petroleum supply. They help to explain why the plateau continues to recede into the horizon—and why, on a global view, Hubbert's Peak is still not in sight.
