OIL DEPLETION?
Good News In
good news for the SUV set, Daniel Yergin's Cambridge Energy
Research Associates (CERA), is predicting we will soon be awash
in light, sweet crude - ideal for making gasoline. CERA's
Worldwide Liquids Capacity
Outlook To 2010� Tight Supply Or Excess Of Riches predicts
we humans will have 6 to 7.5 million barrels per day of excess
capacity and we can expect an extended period of lower prices
� perhaps by 2007. Petroleum production will be expanding
faster than demand over the next 5 years. The report has
tabulated 20 to 30 new projects with a capacity of over 75,000
barrels per day that will become available in each and every
year until 2010. By then, worldwide production could increase by
up to 16 million Bbl/day. However, most of the increased
production will come from reworking existing fields, rather than
new oil discoveries, and after 2010 the majority of new
production will come from OPEC. CERA
doesn't believe in peak oil, at least not before 2010, and
probably not before 2020. The report indicates that the
�inflexion� point will come between 2030 and 2040. Moreover,
rather than a �peak,� it will be an �undulating plateau�
that will continue for several decades. OPEC, the company
claims, will be able to add 8.8 Mbl/day by 2010 and can continue
its expansion � at a somewhat slower rate � beyond 2010.
Non-OPEC production will experience a robust increase through
2010, and then slow significantly thereafter. Unconventional oil
production will increase throughout this period, supplying
almost 35 percent of the world's oil by 2020. Then
Yergin adds a sobering caveat: "The main risks to our
Supply Expansion scenario are above ground, not below ground �
changes in the political and operating climate that could delay
expansion.� In CERA�s downside �Delay and Disruption�
scenario, capacity increases by only 11.5 million barrels
between 2004 and 2010. Whoops. What
is the implication? Will delayed projects and disruptions in the
supply chain lead to temporary shortages before "Peak
Oil" hits us? Perhaps we should review CERA's implied
assumptions. They are, after all, the basis of CERA's optimistic
conclusions.
Assumptions Underlying
every data analysis and series of conclusions is a collection of
assumptions. In order to avoid oil shortages, temporary or
longer term, for example, we have to make multiple assumptions
about our ability to find, produce, transport, refine and
distribute oil (the supply chain). At some point in our
analysis, these assumptions have to be tested for credibility. Will
they hold up under careful examination? Assumption
# 1. Peace in Iraq. The
future of Iraq rests on the outcome of an escalating cultural
conflict between Islamist and Western values. Until that gets
resolved, we can only guess at the future of Iraqi oil
production. Assumption
# 2. Political and labor stability. Assumption
# 3. Islamist terrorist activity will not disrupt the supply
chain. Islamist
terrorist activity, whether sporadic or sustained, will continue
to be a potential threat to the flow of oil, not only in the
nations of the Caspian, the Middle East, and North West Africa,
but also within the borders of consuming nations. Assumption
# 4. The proven reserves claimed by OPEC actually exist. Assumption
# 5. There will not be a substantial increase in reserve
depletion rates. Assumption
# 6. All proven and potential reserves will be produced on
schedule. Assumption
# 7. Middle Eastern production capacity will continually
increase, reaching ~ 29 Mbl/d by 2010 and at least 43 Mbl/d by
2020. Assumption
# 8. The EROEI of all oil production exceeds 1. The
average EROEI of world oil production has been declining. I read
somewhere that before 1950 the EROEI for oil was more than
100:1. By the 1970s it had dropped to 30:1, and by 2005 the
average EROEI on new production had fallen to 10:1. As we go for
oil in increasingly difficult environments (deep under the
ocean, open pit mining, etc.) the EROEI will decline further. We
have to face the facts. Just because there is oil in the ground
does not mean it is practical to extract. Every well has its
cost in money AND energy. At some point the EROEI for every well
will fall to less than 1, making oil from that well an
impractical resource for energy. Assumption
# 9. Unconventional oil production will increase throughout this
period, supplying almost 35 percent of the world's oil by 2020. We
expect to find oil beneath polar ice and permafrost in the
Artic. Although total recoverable oil is something of a mystery
at this point, figure 55 to 100 Bbl (maybe more). Unfortunately,
exploration, production and transportation in this frigid
environment are no fun. And costly. So don't expect polar oil to
yield enough production to avoid oil shortages. We
are learning how to drill in the deep waters (over 2,500 meters)
of the ocean. There is oil in the Gulf of Mexico, along the
coastal shelves of South America and Africa, and a number of
other locations around the world. Recovery takes time, is a
technical and operations challenge, and is very costly. Add
another 80 to 120 Bbl of oil to the reserves we will ultimately
recover. In
addition, one can expect we humans will pump out a limited
amount of heavy oil and oil from coal bed methane deposits. If
we add up all of these resources, we probably have up to 1.1 Tbl
of unconventional oil to play with over the next 20 years. But
our estimate of annual production is much lower. Technical,
weather, geography, political, environmental, cost and EROEI
factors will limit total production to around 100 Bbl from 2005
to 2020. This estimate � by the way - mirrors the Energy
Outlook projections made by ExxonMobil in its "World
Liquids Production Outlook" presentation. To
these numbers we need to add, as CERA does, Natural Gas Liquids
(NGL) and condensates as unconventional oil. If we add all of
these forms of unconventional oil together, CERA's projections
appear reasonable. Assumption
# 10. There is sufficient infrastructure to support a vigorous
increase in production. Assumption
# 11. Non-Muslim engineers, technicians and laborers will be
permitted to work in the fields of the Middle East, North West
Africa, and countries adjacent to the Caspian basin. Assumption
# 12. There is sufficient capital to fund the proposed supply
chain activities. Assumption
# 13.There will be a dramatic decrease in the growth rate
of oil consumption. Assumption
# 14. As a result of over production, we will be awash in oil. Assumption
# 15. The price of oil will decline. Assumption
# 16. Resource nationalism will not disrupt world oil markets. Because
the North Sea fields are declining, West Africa is in turmoil,
Venezuela is politically unstable, Iraq is a crap shoot, Saudi
Arabia is vulnerable to revolution, and Putin plans to use
Russia's petroleum as a political weapon. China is buying up
every drop it can find. The Italians have pointed out that the
geographical flows of crude oil favor refineries on the
Mediterranean coast over refineries located in North America. Hmmmm.
Are we witnessing an increase in resource nationalism? The
industrialized nations have no choice. Oil shortages will create
a growing cadre of unemployed citizens and declining GDP.
Political survival means drilling in every plausible location on
this planet and competing with other nations for the oil that is
left. The
race is on. Assumption
# 17. Technology will save us. For
example, much has been made about the use of CO2 injection to
increase recoverable reserves. Granted. It is possible to
recover 60 percent (or more) of the oil that in the ground as we
humans struggle to liberate every drop of oil from existing
reservoirs. But many of our older oil formations have already
been flushed with fluids and chemicals in an effort to increase
production. Consequently, the use of newer technology will not
always yield dramatic improvements in mature field recovery. New
finds, on the other hand, provide an opportunity to secure
higher increases than older formations. Recovery rates will also
be higher and faster for light oils than for heavier crude. And
finally, it may - or may not - be economical to use newer
technology, such as CO2 injection, on some wells. What does this
all mean? Over a period of years, average world recovery rates
are more likely to be in the 45 to 50 percent range. And
there is a downside to the application of reserve enhancement
technology. If we increase the rate at which we drain our
available reserves, - depletion happens sooner. Assumption
# 18. Higher prices will encourage the production of more oil.
Reality Check CERA's
optimistic views are in the minority. John
S. Herold, Inc. PFC
Energy "J.
Robinson West, chairman of the consulting group PFC Energy, has
floated with administration officials his idea of a sustained
national dialogue on energy that includes all stakeholders. And
his group has gathered what may be the best statistics available
on the seriousness of the supply-demand crunch. West
argues that the oil market squeeze will only get worse -- and
more vulnerable to political disruptions. By his estimate, about
77 percent of proven oil reserves are controlled by nationalized
oil companies rather than by the international majors such as
Exxon Mobil. Meanwhile, non-OPEC sources of supply are slowly
declining. �. Even if more crude were suddenly discovered,
there's a worldwide refining squeeze, with almost no spare
capacity left. The
day of reckoning is less than 15 years away, by West's
calculation. Assuming fairly slow growth in demand of about 1.8
percent annually, he reckons that by 2020 demand will total over
100 million barrels per day, and OPEC will be unable to fill the
supply gap. Unless the United States and other consuming
countries have taken steps to reduce consumption, the
supply-demand imbalance will throw the world into economic chaos
�.. " ChevronTexaco ExxonMobil We
should pay attention to ExxonMobil's judgment. "This
assessment (of increased OPEC production) is somewhat
ominous" writes Dr. Colin Campbell, a founder of ASPO,
"� such production increases are only possible from Iraq,
Saudi Arabia, Kuwait, and the United Arab Emirates. For these
countries, and indeed for most OPEC members, petroleum and
petroleum products are their only significant export. As such,
they have a vested interest in obtaining the best possible price
for their non-renewable resources. OPEC nations would be quite
unlikely to increase production as rapidly as needed unless
compelled to do so." And in the ASPO
Newsletter 55 (July 2005), Dr. Campbell writes "It is
significant that the first quarter production of most of the
major oil companies is falling : ExxonMobil -3%; Chevron -6% ;
Shell -8% ; Repsol YPF -7%., while Phillips-Conoco maintained
its level with BP at least reporting a 2% increase (see
Petroleum Review, June 2005). All the more reason that the
public should heed the silent alarm sounded by the ExxonMobil
report, which is more credible than other predictions for
several reasons. First and foremost is that the source is
ExxonMobil. No oil company, much less one with so much
managerial, scientific, and engineering talent, has ever
discussed peak oil production before. Given the profound
implications of this forecast, it must have been published only
after a thorough review." Shell Aramco BP
Conclusion Delayed
projects and disruptions in the oil supply chain, coupled with
current rates of depletion, could lead to temporary shortages
long before "Peak Oil". Why?
Because the issue is NOT how much oil do we have left in the
ground. The issue is � How much oil can we produce? Sure.
Calculating available reserves (proven, probable, and possible)
is important because these projections give us a rough idea when
peak oil production will occur. But when we talk about oil as a
business, we have to include the challenges of exploration,
production and transportation. It will be tough, for example, to
find and pump this stuff from black holes in remote Siberia or
the cold blue ice of the Artic. Emerging technologies may permit
us to drill 10,000 meters below the surface of the ocean, but
it's still an incredible operations headache. Producing oil from
shale and sand is possible, but finding enough water and natural
gas to sustain production will be difficult. And then there's
another problem. Most of the world's remaining reserves and
transport routes are located within the boundaries of nations
that are politically unstable, have unpredictable regimes, may
ignore their contractual obligations, or have a large faction of
politically active extremists. Given
the seemingly infinite number of imponderable variables and
assumptions, a credible forecast based on available information
(facts) is impossible. That's why I developed a series of
scenarios for my book - Oil, Jihad and Destiny. Each scenario
provides a way to organize a set of related facts and
assumptions. Because they begin as a hypothesis, scenarios can
be tested against known data points. We can also estimate each
scenario's probability. Although the resulting "Best
Case" scenario in my model projects adequate oil production
through 2020, I gave it a probability of only 40 percent. The
"Production Crisis" in my book describes a more likely
scenario. Oil shortages will drive intermittent periods of
recessive economic activity. Recession drives down demand. Oil
surpluses appear and prices decline. A sluggish economic
recovery occurs until oil production again falls behind demand.
Consumption then decreases or is stagnant, and the cycle is
repeated. In
the final analysis, however, the pivotal point for all of these
assumptions and scenarios rests on the motivations, political
realities, and production capabilities of the Middle East. If
they are willing to act in the selfish-best-interest of the
industrialized nations, then CERA's "Best Case"
scenario is possible. If
not, we are in for a long period of cultural and economic agony. ©

It's All In The Assumptions
by Ronald R. Cooke
The Cultural Economist
Author, "Oil, Jihad &
Destiny" and "Detensive Nation"
July 28, 2005
A key element for any increase in Middle East oil production has
to be Iraq. Estimates of found oil range from 46 to 112 Bbl,
with another 100 Bbl a strong "maybe it's there". If
there is no peace in Iraq, or if Iraq succumbs to the policies
of an Islamic Theocracy, then Iraq's contributions to OPEC's
annual production volumes will never reach the levels envisioned
by the International Energy Agency (IEA). If Iraq's government
is stable, and favors a high production policy, then world oil
supplies will be a little closer to the IEA's projections
through 2020.
Any optimistic analysis of oil production must assume there will
be relative political and labor stability in the Middle East,
North West Africa, South America, and Caspian regions. As recent
events have shown, however, these areas are prone to conflict
that disrupts the flow of oil. Up until 2004, temporary
disruptions in one region could usually be replaced by
production from other resources. Going forward, there may not be
sufficient spare capacity to cover lost production from one or
more regions. As a result, sporadic shortages are a possible
reality.
Islamist terrorist activity will continue to disrupt the supply
chain from time to time. The land locked Caspian, for example,
could be the source of 60 Bbl of oil. Maybe more. And these
wells are coming on-line. But most of the oil in this region
must pass through a very long pipeline in order to reach the
consumer. History suggests political volatility in this region
will eventually disrupt supply chain operations. Perhaps for
multiple years.
It is unlikely the proven reserves claimed by OPEC actually
exist. Many believe they are a fabrication of the quota
justifications that occurred in the 1980s. Furthermore, the
claim that "Proven" reserves are increasing needs to
be examined because in a sense we are merely talking about
definitions. Words. As the price of oil increases, it becomes
economically feasible to spend more money on production. Make
sense? So the reserves that could not be classified as
"Proven" at $26.00 per barrel become damn attractive
if the price for a barrel goes to $55.00. There isn't any more
oil. It's just that "Probable" oil reserves become
"Proven" oil reserves as the price of oil increases
because we can afford to spend more money on recovery. All we
did was reclassify the definition of the oil we already have in
the ground. No one found any more oil. Not a drop.
Only 4 "super-giant" oilfields have been found outside
the Middle East since 1960 (in Russia, China, Alaska and Mexico)
and all of these - except China - are now in decline. Oil
production is in decline in 33 of the 48 largest oil producing
nations. Using improved technology often increases the rate of
depletion. New finds tend to be smaller and deplete faster.
Worldwide, estimated rates of depletion run as high as 8 percent
per year.
This assumption only works if hundreds of exploration and
drilling operations in multiple countries and oceans under a
wide variety of operating conditions and technical challenges
occur on a schedule that coincides with the IEA's demand
projections. Everything has to work. No significant political or
labor conflicts. No ideological confrontation. No financing or
management Snafus. Cooperative weather. And a reasonably
predictable growth in market demand so consumption can equal
production (with a little to spare).
Middle Eastern production capacity will increase. The goal of 29
Mbl/day by 2010, however, is ambitious, and few believe OAPEC
will be able to deliver 43 to 50 Mbl/day by 2020. Exploration
and production will be challenged by Islamist opposition in
Iran, Iraq and Saudi Arabia (and perhaps elsewhere). There is a
long list of reserve and technical restraints in this region. We
must also understand that the creation of a large surplus
capacity is NOT in OAPEC's selfish best interest. Faced with
enormous population growth and big welfare bills, every Middle
Eastern government knows that when the oil is gone, their regime
is in trouble. Leaders may determine they can actually make more
money, and enjoy greater personal longevity, - by pumping less.
EROEI. Energy Returned On Energy Invested means that the energy
derived from exploration, production, refining, and
transportation exceeds the energy consumed for these activities.
We tend to forget. If the EROEI of any energy resource is 1 or
less, then doing that activity no longer provides a net addition
to our stockpile of energy.
We have inherited up to 7 Tbls of oil trapped in sand or shale
formations. But that is a misleading number. Only 5 Tbl are
worth mining and of that number, perhaps 25 percent will be
feasible to produce because production cost and EROEI factors
make extensive mining impractical. Given the production problems
associated with squeezing oil from rock and sand, the rate of
production will be painfully slow. A goal of 15 to 18 Mbl per
day by 2020 from recoverable reserves of 620 to 910 Bbl appears
reasonable.
Oil is a cyclical business. Prices bounce up and down because
there is almost always a mismatch between supply and demand. For
a number of reasons, exploration and production investments have
not kept up with projected increases in demand. That investment
deficit has left us with insufficient spare production capacity
to sustain the world's projected economic growth. Even if we
have ample reserves in the ground, there is no guarantee enough
oil wells will be developed in time to avoid sharply higher
prices and possible shortages. We don't have enough oil rigs,
tankers, petroleum engineers, or refinery capacity. The problem
is systemic and will take several years to resolve.
Non-Muslim engineers, technicians and laborers will be permitted
to work in the fields of the Middle East, North West Africa, and
countries adjacent to the Caspian basin. However, Islamist
activity and local sociopolitical conflict could jeopardize
personnel security. Iran's new government, for example, has made
it clear that non-Muslim foreigners are not welcome to bid, or
work, in Iran's oil patch.
There is sufficient capital to fund all of the proposed supply
chain activities if one assumes the credit markets will not be
overly stressed by other economic events, such as a collapse of
the market for Mortgage Backed Securities or a massive default
on the loans outstanding to Hedge Funds.
Emerging
nations, like China and India, will increase their per-capita
and total consumption of oil. Although I fully expect a decrease
in the growth rate of oil consumption will occur, it will - as I
point out in "Oil, Jihad and Destiny" � be due to
recessive factors. Production will equal consumption only if
there is a destruction of natural demand or if shortages force
reduced consumption. In either case, the rate of growth
decreases.
It is more likely that Saudi Arabia will continue to act as a
swing producer, restricting its production in order to encourage
higher prices. Indeed, Saudi Aramco engineers may welcome the
opportunity to take key wells off-line for service if the world
appears to be "awash" in oil.
It is highly likely that the price of oil will fall below $40.00
per barrel. The history of the oil industry is characterized by
volatile changes in price because of the chronic imbalance
between supply and demand. But a temporary decline in price is
no basis for making either public policy or personal choice
decisions. For every short term decline, expect a subsequent
increase in the price. The long term trend for all petroleum
prices is UP.
If there is so much oil available for production, why are we
drilling new wells in deep water? They are very expensive,
challenge our best technology, pose an environmental hazard, and
are at the mercy of the sea. Why don't we just drill on land?
Optimists claim that continuing improvements in computer,
exploration, and drilling technology will sharply increase oil
production. In truth, the oil industry has been continually
improving upstream exploration and production technology since
the birth of the oil age. Engineers are currently hard at work
on improvements for drilling fluids, drill bits, directional
drilling, multilateral drilling, sensors, GPS, drill casing
materials, CO2 injection, reservoir modeling software, and a
thousand other opportunities to increase recovery operations.
The point is, there is no magic solution that will suddenly
increase our reserves. Almost every technical solution has
already been explored. Yes. New technologies will increase
production. But the net impact is more likely to be incremental
� not revolutionary.
The classic economist assumes higher prices will stimulate
greater production. And it usually works. But our hydrocarbon
resources are finite. New production involves a complex series
of challenges that can take several years to overcome. In order
to continue along the growth curve of projected demand through
2020, we humans will have to consume most of our
"Proven" reserves, convert most of our
"Probable" reserves into "Proven" reserves,
and maximize a phenomenon peculiar to the petroleum industry
called "Reserve Growth". Oil prices will have to
increase in order to justify the economics of this sequence.
Total oil production, however, will continue to be limited by
the factors discussed above in Assumptions 1 � 17.
Wall Street firm John S. Herold Inc. of Norwalk, CT http://www.herold.com/
has estimated peak production for about two dozen oil companies.
Without substantial new investment and additional discoveries,
the company believes that French oil company, Total S.A.,
will reach peak production in 2007. Exxon Mobil, ConocoPhillips,
BP, Royal Dutch/Shell Group, and the
Italian producer, Eni S.p.A. will hit peak production in 2008.
In 2009, Herold expects ChevronTexaco Corp. to peak. In Herold's
view, each of the world's seven largest publicly traded oil
companies will begin seeing production declines within the next
48 months or so.
From the July 1, 2005 edition of the Washington Post comes this commentary by Robin West, in an article entitled "Crude Courage"
Dave O'Reilly, the chairman of ChevronTexaco: �The time
when we could count on cheap oil and even cheaper natural gas is
clearly ending.� Chevron has started a petroleum resource
discussion on the WEB at http://www.willyoujoinus.com/.
Vice President of Policy, Government and Public Affairs,
Patricia Yarrington believes the site is an important first step
in a new dialogue. "We developed a campaign that is rooted
in the real issues facing our industry. They are issues that
affect everyone who has a stake in energy � consumers,
businesses, policymakers, environmentalists, educators and
political leaders. We think it�s a very compelling campaign
about a very compelling subject."
ExxonMobil projects non-OPEC Crude and Condensate production
will plateau before 2015 in its Energy Outlook presentation.
ExxonMobil proposes that increased demand be met in two ways.
The first is greater fuel efficiency. (How often do you hear oil
companies pleading with us to buy cars that use less
gas?). The second way is for OPEC to vastly increase production.
The Royal Dutch/Shell Group of Companies, in their
presentation "Visions of the Future: Shell launches new
Global Scenarios looking forward to 2025" lays out the
risks: " The energy scene will be reshaped by the
combination of three discontinuities: a relinking of energy
consumption and economic growth as a result of the faster
development of emerging countries, the emergence of carbon as a
commodity in its own right, and the search for energy security.
The latter will remain a key consideration during the scenario
time span, potentially leading to far more politicized energy
relations and creating new sources of tensions among countries
as well as new opportunities for entrepreneurship and
cooperation. Ambiguity will persist as to what the term
�energy security� covers: physical supplies can be
threatened by rising international insecurity as well as by
depletion of supply sources. Insecurity can also result from the
lack of investment in enhanced recovery of existing sources, in
new energy sources and/in infrastructures."
Although Aramco, Saudi Arabia's national oil company (and the
largest oil company in the world), has launched a massive
expansion program, it could be 5 to 7 years before we see any
meaningful increase in production from this additional
investment. Worse, Saudi officials have apparently told the Bush
Administration that OPEC will be unable to meet projected oil
demand in 10 to 15 years. Saudi Arabia would have to produce up
to one half of the increased demand, with most of the remainder
coming from Kuwait, the United Arab Emirates, and Iraq. In order
for the CERA scenario to work, the cartel would have to boost
its production to 50 Mbl/d. Few believe that will happen. Saudi
Arabia, for example, has apparently calculated that its
contribution will fall short by up to 5 Mbl/d by 2024.
Only BP appears to agree with CERA. There "is no
shortage of oil and gas resources for the long term" (From
"Making the right choices, The energy year in
perspective"). The world has enough proved reserves of oil
to last 40 years "at current consumption levels".
Higher prices, BP claims, have been caused by a supply-demand
imbalance that should be resolved with the addition of new
production over the next few years. Incidentally, BP is the only
major independent oil company that had more reserves at the end
of 2004 than it had at the beginning of that year.
