The Problem of Peak Oil
by F. William Engdahl
(2003)
According to the best estimates of a number of respected international
geologists, including the French Petroleum Institute, Colorado School of Mines,
Uppsala University and Petroconsultants in Geneva, the world will likely feel the
impact of the peaking of most of the present large oil fields and the dramatic
fall in supply by the end of this decade, 2010, or possibly even several years
sooner. In other words, we face a major global energy shortage in about seven years.
Peak oil
The problem in oil production is not how much reserves are underground. The
problem comes when large oilfields such as Prudhoe Bay Alaska or the fields of
the North Sea pass their peak output. Much like a bell curve, oil fields rise to
a maximum output or peak. The peak is the point when half the oil has been
extracted. In terms of reserves remaining it may seem there is still ample oil.
But it is not as rosy as it seems.
The oil production may hold at the peak output for a number of years before
beginning a slow decline. Once the peak is past however, the decline can become
very rapid. Past the peak, there is still oil, but each barrel becomes more
difficult to exploit, and more costly, as internal well pressures decline or
other problems make recovery more expensive for each barrel. The oil is there but
not at all easy to extract. The cost of each barrel past peak is increasingly
higher as artificial means are employed to extract it. After a certain point it
becomes uneconomical to continue to try to extract this peak oil.
Because most oil companies and agencies such as the US Department of Energy
speak not of peak oil, but of total reserves, the world has a false sense of
energy supply security. The truth is anything but secure.
Case studies
Some recent cases make the point. In 1991 the largest discovery in the Western
Hemisphere since the 1970's, was found at Cruz Beana in Columbia. But its
production went from 500,000 barrels a day to 200,000 barrels in 2002. In the
mid-1980's the Forty Field in North Sea produced 500,000 barrels a day. Today it
yields 50,000 barrels. One of the largest discoveries of the past 40 years,
Prudhoe Bay, produced some 1.5 million barrels a day for almost 12 years. In 1989
it peaked, and today gives only 350,000 barrels daily. The giant Russian Samotlor
field produced a peak of 3,500,000 barrels a day. It has now dropped to 325,000 a
day. In each of these fields, production has been kept up by spending more and
more to inject gas or water to maintain field pressures, or other means to pump
the quantity of oil. The world's largest oil field, Ghawar in Saudi Arabia,
produces near 60% of all Saudi oil, some 4.5 million barrels per day. To achieve
this, geologists report that the Saudis must inject 7 million barrels a day of
salt water to keep up oil well pressure, an alarming signal of near collapse of
output in the world's largest oil kingdom.
The growing problem of peak oil has been known among oil industry insiders
since the mid-1990's. In 1995, the leading oil consulting firm, Petroconsultants
in Geneva, published a global study, 'The World Oil Supply.' The report cost
$35,000, written for the oil industry. Its author was petroleum geologist, Dr.
Colin Campbell. In 1999 Campbell testified to the British House of Commons,
'Discovery of (new oil reserves) peaked in the 1960's. We now find one barrel for
every four we consume ...'
No new giant discoveries
After OPEC raised oil prices in the 1970's, non-OPEC oil projects began to be
profitable in the North Sea, Alaska, Venezuela and other places. Oil production
increased markedly. At the same time, in response to the higher oil price, many
industrial countries like France, Germany USA, Japan dramatically increased the
energy from nuclear power plants. The combination gave the illusion that the oil
problem had vanished. It has not, far from it.
If in fact many of today's major sources of oil have peaked, and are about to
fall off drastically, and at the same time, if world energy demand continues to
grow, and not enough oil is found even to replace existing depletion, the global
economy faces a crisis of staggering dimension.
According to a recent report from the Colorado School of Mines, 'The World's
Giant Oilfields,' the world's '120 largest oilfields produce close to 33 million
barrels a day, almost 50% of the world's crude oil supply. The fourteen largest
account for over 20%. The average age of these 14 largest fields is 43.5 years.' 1
The above study concludes that 'most of the world's true giants were found
decades ago.' Over the past 20 years despite investment of hundreds of billions
dollars by major oil companies, results have been alarmingly disappointing.
The world's major oil companies - Exxon-Mobil, Shell, ChevronTexaco, BP,
ElfTotal and others - have invested hundreds of billions of dollars in finding
enough oil to replace the existing oil supply sources. Between 1996 and 1999,
some 145 companies spent $410 billion to find enough oil only to keep their daily
production stable at 30 million barrels a day. From 1999 to 2002, the five
largest companies spent another $150 billion and their production grew only from
16 million barrels a day to 16.6 million barrels, a tiny increase. With the
collapse of the Soviet Union in the early 1990's, western oil companies placed
high hopes on the oil potentials of the Caspian Sea in Central Asia.
Disappointing Caspian results
In December 2002, just after US troops took Afghanistan, BP, a major oil
company announced disappointing Caspian drilling results which suggested that the
'oil find of the century' was little more than a drop in the ocean. Instead of
earlier predictions of oil reserves above 200 billion barrels, a new Saudi Arabia
outside the Middle East, the US State Department announced, 'Caspian oil
represents 4% of world reserves. It will never dominate the world's markets.'
PetroStrategies published a study estimating that the Caspian Basin contained a
mere 39 billion barrels of oil, and of a poor quality. Soon after this news, BP
and other western oil companies began reducing investment plans in the region.
Interest in West Africa
One of the most active areas of new exploration is in the offshore region of
West Africa from Nigeria to Angola. President Bush made a high profile trip to
the region earlier in the year, and the US Pentagon has signed military basing
agreements with two small strategic islands, Principe and San Tome, insuring a
military presence should anything threaten the flow of oil across the Atlantic.
Yet, while the volume of oil is important, it also is hardly a new Saudi Arabia.
Geologist Campbell estimates that if all deepwater oil, perhaps 85 billion
barrels, were produced from fields off Brazil, Angola and Nigeria, it would meet
global demand for 3-4 years.
Growing energy demand
Against the prospect that many of the largest oil fields today are in a marked
decline in output, world demand for oil is rising ruthlessly, marked by the
growing economies of China, India and Asia. Even at today's weak GDP growth
rates, economists estimate that world demand for oil at today's prices will rise
by some 2% per year.
Ten years ago, China was not a factor in world import of
oil. It produced most of its limited needs domestically. Beginning 1993 however,
China began to import oil to meet its economic needs. By end 2003 China has
surpassed Japan to be the second largest oil importer next to the USA. China now
consumes 20% of total OECD industrial country energy. China oil imports are
rising now by 9% a year and this is predicted to rise significantly in the coming
decade, as China emerges as the world's largest industrial nation. China
currently is growing at 7-8% a year. India has recently emerged as a rapidly
growing economy as well. Combined they account for some 2.5 billion of the world
population. Little wonder that China vehemently opposed the US unilateral war
against Iraq in the UN Security Council. The China National Petroleum Company had
long sought to secure a major oil supply from Iraq.
What Cheney knew in 1999
In a speech to the International Petroleum Institute in London in late 1999,
Dick Cheney, then chairman of the world's largest oil services company,
Halliburton, presented the picture of world oil supply and demand to industry
insiders. 'By some estimates,' Cheney stated, 'there will be an average of two
percent annual growth in global oil demand over the years ahead, along with,
conservatively, a three percent natural decline in production from existing
reserves.' Cheney ended on an alarming note: 'That means by 2010
we will need on the order of an additional fifty million barrels a
day.' This is equivalent to more than six Saudi Arabia's of today's size.
The Achilles heel of the US?
The burning question is where will we get such a huge increase of oil? In the
decade from 1990 to 2000, a total of 42 billion barrels of new oil reserves were
discovered worldwide. In the same period, the world consumed 250 billion barrels.
In the past two decades only three giant fields with more than one billion
barrels each have been discovered. One in Norway, in Columbia and Brazil. None of
these produce more than 200,000 barrels a day. This is far from 50 million
barrels a day which the world will need.
According to the estimates of Colin Campbell and K. Aleklett of Uppsala
University, five countries hold the overwhelming bulk of the world's remaining
oil and could potentially make up the difference as other areas pass their peak.
'The five major producers of the Middle East, namely Abu Dhabi, Iraq, Iran,
Kuwait and Saudi Arabia (including the Neutral Zone), with about half the world's
remaining oil, are treated as swing producers making up the difference between
world demand and what other countries can produce...' 2.
These five countries - Iraq, Iran, Saudi Arabia, Kuwait and the UAE - through
circumstances of geology, contain the oil and gas reserves vital to the future
economic growth of the world. In an article in the January 7, 2002 issue of Oil
and Gas Journal by A. S. Bakhtiari of the National Iranian Oil Company, noted,
'The Middle East (is) simultaneously the most geostrategic area on the globe and
the ultimate energy prize: Two-thirds of global crude oil reserves are
concentrated in five countries bordering the Persian Gulf.' 3
In a paper published in November 2001, eminent Princeton geologist, Kenneth
Deffeyes wrote, 'The biggest single question is the year when world oil
production reaches a Hubbert peak and then declines forever. Both the graphical
and the computer fits identify 2004 as the probable year. The largest single
uncertainty is the enormous reserves of Saudi Arabia.' 4
If the peak oil analysis is accurate, it suggests to the world why Washington
may be willing to risk so much to control Iraq and through its bases there, the
five oil-rich countries. (?)
