The Energy Challenge 2004 – Petroleum | ||||
|
Recent high prices of oil have raised the visibility of the petroleum challenge considerably, but there is still more heat than light being generated on the subject. For the first weeks of the recent price surge, most writers were trying to lay blame on OPEC for acting like robbers. In fact, as analysts are now beginning to realize, prices have gone up in 2 stages. The first in 2003 was simply due to the weak dollar. During that stage, the price in Euros barely budged. The second (2004) is due to WW demand outstripping supply, aggravated by security concerns. The weak dollar and the security concerns are direct results of Bush programs, i.e. the tax reduction budget deficits, and the war in Iraq.
The gasoline price increases we have seen recently result from 4 primary causes.
You will hear that oil company profits are up 90% and that is true. What you will not hear is that oil company profits have been dismal for several years, which is one of the reasons that no refinery capacity has been added. Even after this nice rise, profits are not excessive. No, I am not a spokesman for the oil industry.
What most people don't know is that USA oil production has been in decline since 1970, with the rate of decline slowly increasing. It's at about 4%/yr. now. We now produce only about 40% of the oil we consume, and oil imports are the single largest item in our very negative balance of payments. If you had to pay at the pump to maintain the military we keep in the middle-east to keep the supply lanes open, (not counting the cost of the war in Iraq), instead of having it buried in the defense budget, gasoline would be over $7.00/gal today.
To make things more interesting, worldwide oil production will probably be in irreversible decline before the end of this decade. The present high oil and gasoline prices are just the first tremors of the earthquake that is coming.
Some months ago Lee Raymond, the chairman of Exxon-Mobil made a presentation that included a curve showing historic oil production (in Mb/d) and projecting future supply and demand. The supply curve, based on production from present known reserves sloped downwards. The demand curve sloped upwards. The growing gap between supply and demand represented new sources that we must discover to support world economic growth. Mr. Raymond made the point that by 2020 we must find enough new oil sources to supply 50 Mb/d. Today Russia and Saudi Arabia are each supplying a little more than 9 Mb/d, and struggling to get to 10. Their combined claimed reserves are about 400 Gb. One can extrapolate that we need to find and develop1100 Gb of new reserves during the next 15 years, or an average of about 75 Gb/yr. During the last 15 years, with plenty of incentive to find new oil sources, we have not averaged 10 Gb/yr.
Let’s forget about economic growth, how about just offsetting declines. If
Mr. Raymond’s curve reflects reality we would still have to find about 30 Gb/yr.
How are we doing? From http://www.ems.org/rls/2004/01/28/oil_supply_short.html
we find the following:
The rate of major new oil field discoveries has fallen dramatically in recent years. There were 13 discoveries of over 500 million barrels in 2000, six in 2001 and just two in 2002, according to the industry analysts IHS Energy. For 2003, not a single new discovery over 500 million barrels has been reported. Key findings of a recent Petroleum Review report are:
Further confirming this trend, recent E&D results strongly support the expectation of a near term peak in oil production. The net present value of all discoveries for the 5 oil majors, during 2001/2/3 was less than their exploration costs.
Six months later, in World Energy, Mr. Raymond admitted that we have to find enough new oil to provide 8x Saudi Arabia’s current output, i.e. at least 5 new Saudi Arabias, or 7 Russias. How likely is that too happen? Oil in the earth’s crust is distributed fractally along a curve of declining field size versus increasing field occurrence. There are very few super giants, a few more giants, more majors, etc. down to many, many insignificant fields. Because they are the easiest to detect, the big ones are found first, and they have been found. There are about 41,000 known oil fields worldwide, of which about 21,000 are termed very small to insignificant. The probability that we have found so many small fields, and overlooked any more big ones, let alone a Saudi Arabia or Russia, is near zero.
Recent events and near future The “D” Words Analysts, economists and industry spokespersons seem very reluctant to talk
about depletion or production decline. Chris Skrebowski of ODAC has analyzed the
2004 BP Statistical review of World Energy and has noted that there were 32
countries that were able to increase production in 2003, vs. 18 countries which
have been in decline for 3 years or more. In 2003 the growers had to increase
production by 7.5% to offset declines of 4.9% for the decliners to give net
world growth of 3.7%. Production from the 18 countries now in sustained decline
peaked in 1997, and had fallen 10.7% by 2003. More countries are joining the
decliners list, their rate of decline is increasing, and the growers list is not
growing, so the burden on those still growing is increasing rapidly.
In 2003 several of the growers increased production by near 10%, mainly by
reopening wells that had been shut in during the price declines at the end of
the last century. Now every one is operating close to or at installed capacity,
so a similar increase cannot be repeated. To increase capacity significantly
will require large investment and some years. Declines however continue to
accelerate. It is only a matter of time, and not much time, before growth is no
longer able to offset declines.
Petroleum Background There is a phenomenon, well known in the oil industry, but little publicized,
that when an oil field has been about 50% depleted, production begins an
irreversible decline. In 1956 a petroleum geologist named M. King Hubbert
applied this concept to an analysis of the lower 48 states, and predicted a
decline of production starting about 1970. He was derided at the time, but lower
48 USA oil production has been in decline since 1970. The phenomenon has been
named the Hubbert Peak, and the production growth and decline curve is often
referred to as a Hubbert Curve.
In 1998, using the best petroleum industry database available, two petroleum
engineers (Campbell and Laherrere) applied a Hubbert analysis to the entire
world, and predicted a peak between 2000 and 2010. Refined analyses since then
focus on 2005 to 2010. In fact, due to economic and political factors, there is
more likely to be an irregular plateau, with possibly several small peaks before
the decline, but an irreversible decline by 2010 seems inevitable. There is a
great deal of real data to support such a view and little but untenable optimism
to support alternative views. “In God we trust, others please bring data!”
We know that Middle East reported reserves grew by about 280Gb between 1987
and 1990, with little additional exploration, and remained constant during the
1990s in spite of continuous production. It is certainly more likely that
reserves are overstated than understated. Middle East reported reserves seem to
have been influenced by OPEC quotas.
The USA consumes about 25% of world oil production and imports >60% of
consumption. With growing demand from developing countries and exploding
populations in OPEC countries, we will not be able to maintain our present share
of world oil, short of occupying the entire Middle East. When world availability
begins to decline, our availability will decline faster. Imagine a world where
natural gas availability has suddenly dropped by half, and oil availability has
gone into irreversible decline, and we have done nothing in advance to
compensate. That is the world we face with the present Congressional energy
bills, and it will lead to an economy that will make the Great Depression look
like a picnic. We can alleviate that probability by addressing energy
conservation and efficiency, and developing renewable electricity alternatives
vigorously, starting now, but that is the polar opposite of the emphasis of
present pending legislation!
So far, in their speeches Vice President Cheney and Secretary Abraham have
looked out 10 to 20 years, but not beyond 20 years. By 2030, oil availability
will be <50% of our peak year (which should occur before 2010), and before
2040 there will be no availability for general energy needs. The pittance
remaining will be allocated to chemicals and agriculture. What kind of world
will we leave our children if we have not succeeded in developing a new
electricity based energy economy long before 2030? What chance do we have to
succeed if we not make good strides by 2010? What can we gain by the present
policy of focusing on accelerated depletion of severely limited supply side
resources?
Petroleum Myths Poor information and silence USGS Disinformation To increase available oil (discovery plus reserve growth) by 1,300 Gb in 30
years, as the USGS projects, means an average increase of 43 Gb per year. This
is more than four times the experience of the 90s, and would mean sustaining the
highest level ever achieved during a single decade, over three decades. Such a
projection simply does not stand the test of reason. The USGS underwent a
Congressional investigation and was found guilty of misleading Congress after
the 1973 oil shock. It is clearly time they were subjected to a new
investigation.

Understanding the Petroleum challenge is hampered by a lot of non-information,
misinformation, disinformation and confusing information. There are numerous
myths floating around, a few of which need to be addressed. Fortunately the most
insidious myth of all, the implied myth of silence on the subject, is now dying.
High oil and gasoline prices have recently led to a growing spate of articles in
the printed media, and frequent mention on TV. Most recently the topic has been
featured in business-oriented magazines like Business Week and Fortune, both in
August 2004. The ability of government and industry to keep the issue under
wraps is rapidly eroding.
In their year 2000 report, the USGS (United States Geologic Survey) project
estimated ultimate recovery (EUR) of 3,000 Gb, with “potential” discovery
plus reserve growth adding 1,300 Gb to reserves from 1996 through 2025. The word
“potential” is not defined. They seem to have taken USA reserve growth
history and applied it to recently reported world reserves, a statistically
invalid approach. With 8 years of the period in question now elapsed, actual
reported discoveries are less than 30% of the needed run-rate. Reserve growth is
not reported, but the highest number that could be inferred is < 80% of the
needed run rate, and the likely number <30%. Both are in decline. A
cumulative number by 2025 above 300Gb (vs. 1300) seems very unlikely.
Many economists pin their hopes on “non-conventional oil,” generally shale
oils, tar sands, Orinoco bitumen and very heavy or very deep oils, not
recoverable or refineable by conventional technology. To do so they forget
recovery rate. For sure, such resources are vastly larger than known
conventional oil. However, after decades and billions of dollars of effort,
shale oil recovery has been abandoned. Tar sand and bitumen recovery are now
about 1% of total oil consumption, and even with economy breaking investment,
are unlikely to exceed 10% of present world demand by 2020. Tar sand recovery is
also an environmental nightmare. Further, it has been estimated that no more
than 1/6 of unconventional resources will ever be energetically recoverable.
Unconventional oil will never be a solution. At best it will slightly reduce the
rate of decline.
Others believe that enhanced recovery technology such as pressurization, water
or steam injection, and horizontal drilling will greatly increase recoverable
oil. For fields that have been in decline for long enough to project the EUR,
and for which enhanced recovery has been employed, recovery has briefly
improved, and then decline has resumed on a steeper curve, leading to the same
EUR. Enhanced recovery usually accelerates depletion, but does not increase
available oil.
Another frequently quoted statistic is reserves to production (R/P) ratio.
Recent BP/Amoco statistics provide an R/P of about 38 years, based on 2002
production rates and known reserves. Optimists note that this ratio has been
near 40 years for at least two decades. There are several problems with this
argument:
The scariest probable myth of all is stated reserves. It is likely that at least
some of the reserve increases claimed by OPEC in the late ‘80s were political,
not geologic. The virtually unchanged reserves during the last 15 years, while
about 120 GB have been produced by OPEC, is simply not credible. Real world
reserves might well be 200 to 300 Gb less than claimed, and the world production
peak might well be in 2004.
Some of the industry's most informed participants believe there is little that
can be done to increase worldwide oil production. Earlier this year, British
Petroleum announced that it will be returning to shareholders all cash flow it
receives in excess of $25US per barrel. For every dollar the company receives
in excess of $25US per barrel, BP will adjust its dividend or increase its
share buyback program to return the cash flow to shareholders. BP has
essentially given up its effort so increase production or even keep production
flat. Instead, the company has chosen to give shareholders back their capital
with interest.
