Technology combined
with massive investment is postponing a visible global production collapse that
cannot be replaced at higher prices. We
already have an accelerating contraction in conventional deliveries only partially
offset by fresh production from Iraq and a couple of others. What is hiding it and making up the short
fall is mostly tight oil of which we have enough to drill ahead of the
expanding shortfall for a few years. The
problem that no one particularly appreciates is that this stop gap oil is
pumped dry in perhaps three years. We
are replacing twenty year oil for three year oil. That means that investment must be replaced
every three years.
Thus if 2000,000
barrels new is good this year and 3000000 is good in year two and 4000000 is
good in year three, then we jump to 7000000 in year four and 9000000 in year
five. You see where this is headed. It becomes impossible to outrun this monkey
sooner than later.
So now we get the feel
good story. And North America can stay
ahead a lot longer than anyone else. The
problem is with everyone else trying now to source reliable oil at any price.
We are solving our
supply issues at huge investment cost and a steady decline in energy security.
Peak
Oil Is Dead, Long Live Peak Oil!
Among the big energy
stories of 2013, “peak oil” -- the once-popular notion that worldwide oil production would
soon reach a maximum level and begin an irreversible decline -- was thoroughly
discredited. The explosive development of shale oil and other
unconventional fuels in the United States helped put it in its grave.
As the year went on,
the eulogies came in fast and furious. “Today, it is probably safe to say we
have slayed ‘peak oil’ once and for all, thanks to the combination of new shale
oil and gas production techniques,” declared Rob
Wile, an energy and economics reporter for Business Insider. Similar
comments from energy experts were commonplace, prompting an R.I.P.headline at Time.com announcing, “Peak Oil is Dead.”
Not so fast,
though. The present round of eulogies brings to mind the Mark Twain’s
famous line: “The reports of my death have been greatly exaggerated.”
Before obits for peak oil theory pile up too high, let's take a careful look at
these assertions. Fortunately, theInternational Energy Agency (IEA), the
Paris-based research arm of the major industrialized powers, recently did just
that -- and the results were unexpected. While not exactly
reinstalling peak oil on its throne, it did make clear that much of the talk of
a perpetual gusher of American shale oil is greatly
exaggerated. The exploitation of those shale reserves may delay the onset
of peak oil for a year or so, the agency’s experts noted, but the long-term
picture “has not changed much with the arrival of [shale oil].”
The IEA’s take on this
subject is especially noteworthy because its assertion only a year earlier that the U.S. would
overtake Saudi Arabia as the world’s number one oil producer sparked the “peak
oil is dead” deluge in the first place. Writing in the 2012
edition of itsWorld
Energy Outlook, the agency claimed not only that “the United States is
projected to become the largest global oil producer” by around 2020, but also
that with U.S. shale production and Canadian tar sands coming online, “North
America becomes a net oil exporter around 2030.”
That November 2012
report highlighted the use of advanced production technologies -- notablyhorizontal
drilling and hydraulic fracturing (“fracking”) --
to extract oil and natural gas from once inaccessible rock, especially
shale. It also covered the accelerating exploitation of Canada’s bitumen (tar
sands or oil
sands), another resource previously considered too
forbidding to be economical to develop. With the output of these and
other “unconventional” fuels set to explode
in the years ahead, the report then suggested, the long awaited peak of world
oil production could be pushed far into the future.
The release of the
2012 edition of World Energy
Outlook triggered a global frenzy of speculative reporting, much of
it announcing a new era of American energy abundance. “Saudi America” was the headline over one such hosanna in
the Wall Street Journal.
Citing the new IEA study, that paper heralded
a coming “U.S. energy boom” driven by “technological innovation and risk-taking
funded by private capital.” From then on, American energy analysts spoke
rapturously of the capabilities of a set of new extractive technologies,
especially fracking, to unlock oil and natural gas from hitherto inaccessible
shale formations. “This is a real energy revolution,” the Journal crowed.
But that was then.
The most
recent edition of World
Energy Outlook, published this past November, was a lot more
circumspect. Yes, shale oil, tar sands, and other unconventional fuels
will add to global supplies in
the years ahead, and, yes, technology will help prolong the life of
petroleum. Nonetheless, it’s easy to forget that we are also witnessing
the wholesale depletion of the world’s
existing oil fields and so all these increases in shale output must be balanced
against declines in conventional production. Under
ideal circumstances -- high levels of investment, continuing technological
progress, adequate demand and prices -- it might be possible to avert an
imminent peak in worldwide production, but as the latest IEA report makes
clear, there is no guarantee whatsoever that this will occur.
Inching Toward the Peak
Before plunging deeper into the IEA’s
assessment, let’s take a quick look at peak oil theory itself.
As developed in the
1950s by petroleum geologist M.
King Hubbert, peak oil theory holds that any individual oil field (or
oil-producing country) will experience a high rate of production growth during
initial development, when drills are first inserted into a oil-bearing
reservoir. Later, growth will slow, as the most readily accessible resources
have been drained and a greater reliance has to be placed on less productive
deposits. At this point -- usually when about half the resources in the
reservoir (or country) have been extracted -- daily output reaches a maximum,
or “peak,” level and then begins to subside. Of course, the field or
fields will continue to produce even after peaking, but ever more effort and
expense will be required to extract what remains. Eventually, the cost of
production will exceed the proceeds from sales, and extraction will be
terminated.
For Hubbert and his
followers, the rise and decline of oil fields is an inevitable consequence of
natural forces: oil exists in pressurized underground reservoirs and so will be
forced up to the surface when a drill is inserted into the ground.
However, once a significant share of the resources in that reservoir has been
extracted, the field’s pressure will drop and artificial means -- water, gas, or chemical insertion --
will be needed to restore pressure and sustain production. Sooner or
later, such means become prohibitively expensive.
Peak oil theory also
holds that what is true of an individual field or set of fields is true of the
world as a whole. Until about 2005, it did indeed appear that the globe
was edging ever closer to a peak in daily oil output, as Hubbert’s followers
had long predicted. (He died in 1989.) Several recent developments
have, however, raised questions about the accuracy of the theory.
In particular, major private oil companies have taken to employing advanced
technologies to increase the output of the reservoirs under their control,
extending the lifetime of existing fields through the use of what’s called “enhanced oil recovery,” or EOR.
They’ve also used new methods to exploit fields once considered inaccessible in
places like the Arctic and deep oceanic waters, thereby opening up the
possibility of a most un-Hubbertian future.
In developing these
new technologies, the privately owned “international oil companies” (IOCs) were seeking
to overcome their principal handicap: most of the world’s “easy oil” -- the stuff Hubbert focused on that comes
gushing out of the ground whenever a drill is inserted -- has already been
consumed or is controlled by state-owned “national
oil companies” (NOCs), including Saudi Aramco, the National
Iranian Oil Company, and the Kuwait National Petroleum Company, among
others. According to the IEA, such state companies control about 80% of
the world’s known petroleum reserves, leaving relatively little for the IOCs to
exploit.
To increase output
from the limited reserves still under their control -- mostly located in North
America, the Arctic, and adjacent waters -- the private firms have been working
hard to develop techniques to exploit “tough oil.” In this, they have largely
succeeded: they are now bringing new petroleum streams into the marketplace
and, in doing so, have shaken the foundations of peak oil theory.
Those who say that
“peak oil is dead” cite just this combination of factors. By extending
the lifetime of existing fields through EOR and adding entire new sources of
oil, the global supply can be expanded indefinitely. As a result, they
claim, the world possesses a “relatively boundless supply” of oil (and natural
gas). This, for instance, was the way Barry Smitherman of the Texas
Railroad Commission (which regulates that state’s oil industry) described the global situation at a recent meeting
of the Society of Exploration Geophysicists.
Peak Technology
In place of peak oil,
then, we have a new theory that as yet has no name but might be called
techno-dynamism. There is, this theory holds, no physical limit to the
global supply of oil so long as the energy industry is prepared to, and allowed
to, apply its technological wizardry to the task of finding and producing more
of it. Daniel Yergin, author of the industry classics,The Prize and The Quest, is a key proponent of this theory. He recently summed up the situation this way: “Advances in
technology take resources that were not physically accessible and turn them
into recoverable reserves.” As a result, he added, “estimates of the
total global stock of oil keep growing.”
From this perspective,
the world supply of petroleum is essentially boundless. In addition to
“conventional” oil -- the sort that comes gushing out of the ground -- the IEA
identifies six other potential streams of petroleum liquids: natural
gas liquids; tar sands and extra-heavy oil;kerogen oil (petroleum solids derived from shale
that must be melted to become usable); shale oil; coal-to-liquids (CTL); and gas-to-liquids (GTL).
Together, these “unconventional” streams could theoretically add several
trillion barrels of potentially recoverable petroleum to the global supply,
conceivably extending the Oil Age hundreds of years into the future (and in the
process, via climate change, turning the planet into an uninhabitable desert).
But just as peak oil
had serious limitations, so, too, does techno-dynamism. At its core is a
belief that rising world oil demand will continue to drive the increasingly
costly investments in new technologies required to exploit the remaining
hard-to-get petroleum resources. As suggested in the 2013 edition of the
IEA’s World Energy Outlook, however,
this belief should be treated with considerable skepticism.
Among the principal challenges to the theory
are these:
1. Increasing Technology Costs:
While the costs of developing a resource normally decline over time as industry
gains experience with the technologies involved, Hubbert's law of depletion
doesn’t go away. In other words, oil firms invariably develop the easiest
“tough oil” resources first, leaving the toughest (and most costly) for
later. For example, the exploitation of Canada’s
tar sands began with the strip-mining of deposits
close to the surface. Because those are becoming exhausted, however,
energy firms are now going after deep-underground reserves using far costlier
technologies. Likewise, many of the most abundant shale oil deposits in
North Dakota have now been depleted, requiring an increasing pace of drilling to maintain
production levels. As a result, the IEA reports, the cost of developing
new petroleum resources will continually increase: up to $80 per barrel for oil
obtained using advanced EOR techniques, $90 per barrel for tar sands and
extra-heavy oil, $100 or more for kerogen and Arctic oil, and $110 for CTL and
GTL. The market may not, however, be able to sustain levels this high,
putting such investments in doubt.
2. Growing Political and Environmental
Risk: By definition, tough oil reserves are located in problematic
areas. For example, an estimated 13% of
the world’s undiscovered oil lies in the Arctic, along with 30% of its untapped
natural gas. The environmental risks associated with their exploitation
under the worst of weather conditions imaginable will quickly become more
evident -- and so, faced with the rising potential for catastrophic spills in a
melting Arctic, expect a commensurate increase in political opposition to such
drilling. In fact, a recent increase has sparked protests in both Alaska
and Russia, including the much-publicized September 2013 attempt by activists
from Greenpeace to scale a Russian offshore oil platform -- an
action that led to their seizure and arrest by Russian commandos. Similarly,
expanded fracking operations have provoked a steady increase in anti-fracking
activism. In response to such protests and other
factors, oil firms are being forced to adopt increasingly stringent
environmental protections, pumping up the cost of production further.
3. Climate-Related Demand Reduction:
The techno-optimist outlook assumes that oil demand will keep rising, prompting
investors to provide the added funds needed to develop the technologies
required. However, as the effects of rampant climate change accelerate, more and more polities are likely to try to
impose curbs of one sort or another on oil consumption, suppressing demand --
and so discouraging investment. This is already happening in the United
States, where mandated increases in vehicle
fuel-efficiency standards are expected to significantly reduce oil
consumption. Future “demand destruction” of this sort is bound to impose
a downward pressure on oil prices, diminishing the inclination of investors to
finance costly new development projects.
Combine these three factors, and it is
possible to conceive of a “technology peak” not unlike the peak in oil output
originally envisioned by M. King Hubbert. Such a techno-peak is likely to
occur when the “easy” sources of “tough” oil have been depleted, opponents of
fracking and other objectionable forms of production have imposed strict (and
costly) environmental regulations on drilling operations, and global demand has
dropped below a level sufficient to justify investment in costly extractive
operations. At that point, global oil production will decline even if
supplies are “boundless” and technology is still capable of unlocking more oil
every year.
Peak Oil Reconsidered
Peak oil theory, as originally conceived by
Hubbert and his followers, was largely governed by natural forces. As we
have seen, however, these can be overpowered by the application of increasingly
sophisticated technology. Reservoirs of energy once considered
inaccessible can be brought into production, and others once deemed exhausted
can be returned to production; rather than being finite, the world’s petroleum
base now appears virtually inexhaustible.
Does this mean that global oil output will
continue rising, year after year, without ever reaching a peak? That
appears unlikely. What seems far more probable is that we will see a slow
tapering of output over the next decade or two as costs of production rise and
climate change -- along with opposition to the path chosen by the energy giants
-- gains momentum. Eventually, the forces tending to reduce supply will
overpower those favoring higher output, and a peak in production will indeed
result, even if not due to natural forces alone.
Such an outcome is, in
fact, envisioned in one of three possible energy
scenarios the IEA’s mainstream experts lay out in
the latest edition of World
Energy Outlook. The first assumes no change in government policies over
the next 25 years and sees world oil supply rising from 87 to 110 million
barrels per day by 2035; the second assumes some effort to curb carbon
emissions and so projects output reaching “only” 101 million barrels per day by
the end of the survey period.
It’s the third
trajectory, the “450 Scenario,” that should raise eyebrows. It assumes
that momentum develops for a global drive to keep greenhouse gas emissions
below 450 parts per million -- the maximum
level at which it might be possible to prevent global average temperatures from
rising above 2 degrees Celsius (and so cause catastrophic climate
effects). As a result, it foresees a peak in global oil output occurring
around 2020 at about 91 million barrels per day, with a decline to 78 million
barrels by 2035.
It would be premature
to suggest that the “450 Scenario” will be the immediate roadmap for humanity,
since it’s clear enough that, for the moment, we are on a highway to hell that
combines the IEA’s first two scenarios. Bear in mind, moreover, that many
scientists believea global
temperature increase of even 2 degrees Celsius would be enough to produce
catastrophic climate effects. But as the effects of climate change become
more pronounced in our lives, count on one thing: the clamor for government action
will grow more intense, and so eventually we’re likely to see some variation of
the 450 Scenario take shape. In the process, the world’s demand for oil
will be sharply constricted, eliminating the incentive to invest in costly new
production schemes.
The bottom line: global peak oil remains in
our future, even if not purely for the reasons given by Hubbert and his
followers. With the gradual disappearance of “easy” oil, the major
private firms are being forced to exploit increasingly tough, hard-to-reach
reserves, thereby driving up the cost of production and potentially
discouraging new investment at a time when climate change and environmental
activism are on the rise.
Peak oil is dead! Long live peak oil!
