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, says Daniel 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."

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."

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."

This is actually the fifth time in modern history that we've seen widespread fear that the world was running out of oil. The first was in the 1880s, when production was concentrated in Pennsylvania and it was said that no oil would be found west of the Mississippi. Then oil was found in Texas and Oklahoma. Similar fears emerged after the two world wars. And in the 1970s, it was said that the world was going to fall off the "oil mountain." But since 1978, world oil output has increased by 30%.

Just in the years 2007 to 2009, for every barrel of oil produced in the world, 1.6 barrels of new reserves were added. And other developments—from more efficient cars and advances in batteries, to shale gas and wind power—have provided reasons for greater confidence in our energy resiliency. Yet the fear of peak oil maintains its powerful grip.

The idea owes its inspiration, and indeed its articulation, to a geologist who, though long since passed from the scene, continues to shape the debate, M. King Hubbert. Indeed, his name is inextricably linked to that perspective—immortalized in "Hubbert's Peak."

….

His prediction was controversial, but when U.S. oil production hit its high point in 1970 and began to decline, soon followed by the shock of the 1973 embargo, Hubbert appeared more than vindicated. He was a prophet. He became famous—and so did Hubbert's Peak.

….

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."

"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.

Hubbert insisted that price didn't matter. Economics—the forces of supply and demand—were, he maintained, irrelevant to the finite physical cache of oil in the earth. But why would price—with all the messages that it sends to people about allocating resources and developing new technologies—apply in so many other realms but not in oil and gas production? Activity goes up when prices go up; activity goes down when prices go down. Higher prices stimulate innovation and encourage people to figure out ingenious new ways to increase supply.

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.

In the oil and gas industry, technologies are constantly being developed to find new resources and to produce more—and more efficiently—from existing fields. In a typical oil field, only about 35% to 40% of the oil in place is produced using traditional methods.

One example is the "digital oil field," which uses sensors throughout the field to improve the data and communication between the field and a company's technology centers. If widely adopted, it could help to recover an enormous amount of additional oil worldwide—by one estimate, an extra 125 billion barrels, almost equivalent to the current estimate reserves of Iraq.

New technologies and approaches continue to unlock new resources. Ghana is on its way to significant oil production, and just a few days ago, a major new discovery was announced off the coast of French Guiana, north of Brazil.

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.

When a field is first discovered, little is known about it, and initial estimates are conservative. As the field is developed, more wells are drilled, and with better knowledge, proven reserves very often increase substantially. A study by the U.S. Geological Survey found that 86 percent of oil reserves in the U.S. were the result not of what was estimated at the time of discovery but of revisions and additions from further development.

Estimates for the total global stock of oil keep growing. The world has produced about one trillion barrels of oil since the start of the industry in the 19th century. Currently, it is thought that there are at least five trillion barrels of petroleum resources in the ground, of which 1.4 trillion are deemed technically and economically accessible enough to count as reserves (proved and probable).

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%.

….

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.
