Oil Prices Rises
"Next generations
are being condemned BACK to pre-industrial living and subsistence farming,
with fierce wars for remaining resources including water, timber and
arable lands. This will only intensify the carbon warming and global
warming effects."
They called Colin Campbell, who helped to found the
London-based Oil Depletion Analysis Centre because he is an industry man
through and through, has no financial agenda and has spent most of a lifetime
on the front line of oil exploration on three continents. He was chief
geologist for Amoco, a vice-president of Fina, and has worked for BP, Texaco,
Shell, ChevronTexaco and Exxon in a dozen different countries.
The end of oil is closer than you think
Continued...."Don't worry about
oil running out; it won't for very many years," the Oxford PhD told
the bankers in a message that he will repeat to businessmen, academics and
investment analysts at a conference in Edinburgh. "The issue is the
long downward slope that opens on the other side of peak production, starting
with higher wholesale pricing . Oil and gas dominate our lives, and their
decline will change the world in radical and unpredictable ways, starting
with high pricing for the consumer, which is already the case. " he
says.
Campbell reckons "global peak production
of conventional oil - the kind associated with gushing oil wells is approaching
fast, or has already gone, we just don't know for sure." His calculations
are based on historical and present production data, published reserves
and discoveries of companies and governments, estimates of reserves lodged
with the US Securities and Exchange Commission, speeches by oil chiefs
and a deep knowledge of how the industry works.
"About 944bn barrels of oil has so far
been extracted, some 764bn remains extractable in known fields, or reserves,
and a further 142bn of reserves are classed as 'yet-to-find', meaning what
oil is expected to be discovered. If this is so, then the overall oil peak
arrives next year," he says.
If he is correct, then global oil production
can be expected to decline steadily at about 2-3% a year, the cost of everything
from travel, heating, agriculture, trade, and anything made of plastic
rises. And the scramble to control oil resources intensifies. As one
US analyst said this week: "Just kiss your lifestyle goodbye."
Has humanity squandard its only opportunity
to
for a sustainable civilisation ?
But the Campbell analysis is way off the
much more optimistic official figures. The US Geological Survey (USGS) states
that reserves in 2000 (its latest figures) of recoverable oil were about
three trillion barrels and that peak production will not come for about 30
years. The International Energy Agency (IEA) believes that oil will peak
between "2013 and 2037" and Saudi Arabia, Kuwait, Iraq and Iran,
four countries with much of the world's known reserves, report little if
any depletion of reserves. Meanwhile, the oil companies - which do not make
public estimates of their own "peak oil"
- say there is no shortage of oil and gas for the long term. "The world
holds enough proved reserves for 40 years of supply and at least 60 years
of gas supply at current consumption rates," said BP this week.
Indeed, almost every year for 150 years,
the oil industry has produced more than it did the year before, and predictions
of oil running out or peaking have always been proved wrong. Today, the industry
is producing about 83m barrels a day, with big new fields in Azerbaijan,
Angola, Algeria, the deep waters of the Gulf of Mexico and elsewhere soon
expected on stream.
But the business of estimating oil reserves
is contentious and political. According to Campbell, companies seldom report
their true findings for commercial reasons, and governments - which own 90%
of the reserves - often lie. Most official figures, he says, are grossly
unreliable: "Estimating reserves is a scientific business. There is
a range of uncertainty but it is not impossible to get a good idea of what
a field contains. Reporting [reserves], however, is a political act."
According to Campbell and other oil industry
sources, the two most widely used estimates of world oil reserves, drawn
up by the Oil and Gas Journal and the BP Statistical Review, both rely on
reserve estimates provided to them by governments and industry and do not
question their accuracy.
Companies, says Campbell, "under-report
their new discoveries to comply with strict US stock exchange rules, but
then revise them upwards over time", partly to boost their share prices
with "good news" results. "I do not think that I ever told
the truth about the size of a prospect. That was not the game we were in," he
says. "As we were competing for funds with other subsidiaries around
the world, we had to exaggerate."
Most serious of all, he and other oil depletion
analysts and petroleum geologists, most of whom have been in the industry
for years, accuse the US of using questionable statistical probability models
to calculate global reserves and Opec countries of drastically revising upwards
their reserves in the 1980s.
"The estimates for the Opec countries
were systematically exaggerated in the late 1980s to win a greater slice
of the allocation cake. Middle East official reserves jumped 43% in just
three years despite no new major finds," he says.
The study of "peak oil" - the point
at which half the total oil known to have existed in a field or a country
has been consumed, beyond which extraction goes into irreversible decline
- used to be back-of-the envelope guesswork. It was not taken seriously by
business or governments, mainly because oil has always been cheap and plentiful.
In the wake of the Iraq war, the rapid economic
rise of China, global warming and recent record oil prices, the debate has
shifted from "if" there is a global peak to "when".
The US government knows that conventional
oil is running out fast. According to a report on oil shales and unconventional
oil supplies prepared by the US office of petroleum reserves last year,
"world oil reserves are being depleted three times as fast as they are
being discovered. Oil is being produced from past discoveries, but the reserves
are not being fully replaced. Remaining oil reserves of individual oil companies
must continue to shrink. The disparity between increasing production and
declining discoveries can only have one outcome: a practical supply limit
will be reached and future supply to meet conventional oil demand will not
be available."
It continues: "Although there is no
agreement about the date that world oil production will peak, forecasts presented
by USGS geologist Les Magoon, the Oil and Gas Journal, and others expect
the peak will occur between 2003 and 2020. What is notable ... is that none
extend beyond the year 2020, suggesting that the world may be facing shortfalls
much sooner than expected."
According to Bill Powers, editor of the Canadian
Energy Viewpoint investment journal, there is a growing belief among geologists
who study world oil supply that production "is soon headed into an irreversible
decline ... The US government does not want to admit the reality of the situation.
Dr Campbell's thesis, and those of others like him, are becoming the mainstream."
In the absence of reliable official figures,
geologists and analysts are turning to the grandfather of oil depletion analysis,
M King Hubbert, a Shell geologist who in 1956 showed mathematically that
exploitation of any oilfield follows a predictable "bell curve"
trend, which is slow to take off, rises steeply, flattens and then descends
again steeply. The biggest and easiest exploited oilfields were always found
early in the history of exploration, while smaller ones were developed as
production from the big fields declined. He accurately predicted that US
domestic oil production would peak around 1970, 40 years after the period
of peak discovery around 1930.
Many oil analysts now take the "Hubbert
peak"
model seriously, and the USGS, national and oil company figures with a large
dose of salt. Similar patterns of peak discovery and production have been
found throughout all the world's main oilfields. The first North Sea discovery
was in 1969, discoveries peaked in 1973 and the UK passed its production
peak in 1999. The British portion of the basin is now in serious decline
and the Norwegian sector has levelled off.
Other analysts are also questioning afresh
the oil companies' data. US Wall street energy group Herold last month compared
the stated reserves of the world's leading oil companies with their quoted
discoveries, and production levels. Herold predicts that the seven largest
will all begin seeing production declines within four years. Deutsche Bank
analysts report that global oil production will peak in 2014.
According to Chris Skrebowski, editor of
Petroleum Review, a monthly magazine published by the Energy Institute in
London, conventional oil reserves are now declining about 4-6% a year worldwide.
He says 18 large oil-producing countries, including Britain, and 32 smaller
ones, have declining production; and he expects Denmark, Malaysia, Brunei,
China, Mexico and India all to reach their peak in the next few years.
"We should be worried. Time is short
and we are not even at the point where we admit we have a problem," Skrebowski
says. "Governments are always excessively optimistic. The problem is
that the peak, which I think is 2008, is tomorrow in planning terms."
On the other hand, Equatorial Guinea, Sao
Tome, Chad and Angola are are all expected to grow strongly.
What is agreed is that world oil demand is
surging. The International Energy Agency, which collates national figures
and predicts demand, says developing countries could push demand up 47% to
121m barrels a day by 2030, and that oil companies and oil-producing nations
must spend about $100bn a year to develop new supplies to keep pace.
According to the IEA, demand rose faster
in 2004 than in any year since 1976. China's oil consumption, which accounted
for a third of extra global demand last year, grew 17% and is expected to
double over 15 years to more than 10m barrels a day - half the US's present
demand. India's consumption is expected to rise by nearly 30% in the next
five years. If world demand continues to grow at 2% a year, then almost 160m
barrels a day will need to be extracted in 2035, twice as much as today.
That, say most geologists is almost inconceivable.
According to industry consultants IHS Energy, 90% of all known reserves are
now in production, suggesting that few major discoveries remain to be made.
Shell says its reserves fell last year because it only found enough oil to
replace 15-25 % of what the company produced. BP told the US stock exchange
that it replaced only 89% of its production in 2004.
Moreover, oil supply is increasingly limited
to a few giant fields, with 10% of all production coming from just four fields
and 80% from fields discovered before 1970. Even finding a field the size
of Ghawar in Saudi Arabia, by far the world's largest and said to have another
125bn barrels, would only meet world demand for about 10 years.
"All the major discoveries were in the
1960s, since when they have been declining gradually over time, give or take
the occasional spike and trough," says Campbell. "The whole world
has now been seismically searched and picked over. Geological knowledge has
improved enormously in the past 30 years and it is almost inconceivable now
that major fields remain to be found."
He accepts there may be a big field or two
left in Russia, and more in Africa, but these would have little bearing on
world supplies. Unconventional deposits like tar sands and shale may only
slow the production decline.
"The first half of the oil age now closes,"
says Campbell. "It lasted 150 years and saw the rapid expansion of industry,
transport, trade, agriculture and financial capital, allowing the population
to expand six-fold. The second half now dawns, and will be marked by the
decline of oil and all that depends on it, including financial capital."
So did the Swiss bankers comprehend the seriousness
of the situation when he talked to them? "There is no company on the
stock exchange that doesn't make a tacit assumption about the availability
of energy," says Campbell. "It is almost impossible for bankers
to accept it. It is so out of their mindset."
Crude Alternatives
"Unconventional" petroleum reserves,
which are not included in some totals of reserves, include:
Heavy Oils
These can be pumped just like conventional
petroleum except that they are much thicker, more polluting, and require
more extensive refining. They are found in more than 30 countries, but about
90% of estimated reserves are in the Orinoco "heavy oil belt"
of Venezuela, which has an estimated 1.2 trillion barrels. About one third
of the oil is potentially recoverable using current technology.
Tar Sands
These are found in sedimentary rocks and
must be dug out and crushed in giant opencast mines. But it takes five to
10 times the energy, area and water to mine, process and upgrade the tars
that it does to process conventional oil. The Athabasca deposits in Alberta,
Canada are the world's largest resource, with estimated reserves of 1.8 trillion
barrels, of which about 280-300bn barrels may be recoverable. Production
now accounts for about 20% of Canada's oil supply.
Oil Shales
These are seen as the US government's energy
stopgap. They exist in large quantities in ecologically sensitive parts of
Colorado, Wyoming and Utah at varying depths, but the industrial process
needed to extract the oil demands hot water, making it much more expensive
and less energy-efficient than conventional oil. The mining operation is
extremely damaging to the environment. Shell, Exxon, Chevron Texaco and other
oil companies are investing billions of dollars in this expensive oil production
method.
