It will be interesting to see how Sen. Murkowski weighs in on the "hidden"
oil reserves in Alaska.
In the meantime, I must protest "kennj's" mode of discourse. It is
unprofessional and not acceptable in a professional discussion group.
Let us define a geological formation as a continuous region of subsurface
rock which was produced by the same historic geological event, regardless of the
time span involved. Let us define an oil reservoir as a subregion within that
formation containing crude oil distributed in one or more fields subject to a
common pressure gradient.
It is a well known fact that production from any reservoir will rise from an
initial value to a peak or plateau and then descend to a point where it is no
longer economically attractive, leaving MOST of the oil in the ground ! In
the mode of descent, it is often necessary to inject some other material into
the reservoir [ very carefully ] in order to maintain a pressure adequate to
lift the oil to the surface. These materials include CO2, fresh water, natural
gas, nitrogen and salt water. And if some of the water comes back up with the
crude, it must be separated from the latter. All of this of course takes
energy.
For example, the Ghawar collection of reservoirs in Saudi Arabia requires the
injection of 32 barrels of sea water to bring up 100 barrels of crude. This
collection produces about six percent of World crude-oil production.
In the 20th Century, there were several arguments at different times over
when World production would peak. Their principal focus was on techniques of
projecting future production from active reservoirs, based on past history and
estimates of reserves in the ground. In that sense at least, one could say that
the arguments were about some "theory of peak oil" [ in the street or
judicial sense of "theory", not the scientific
sense. ] .
This time things are different. In the 1990's, Matthew Simmons, an engineer
formerly employed by Saudi Aramco, began to have doubts about some of the
statements Saudi engineers were making about the condition of Saudi reservoirs. He
read some 200 papers presented by Saudi engineers at international confabs,
confirmed his suspicions and then wrote a book, Twilight in the Desert, or
something to that effect.
That stirred people up, and the more knowledgeable among them began to make
their own calculations, in many cases without using data for reserves, which
more than any other industry data, are full of errors, omissions and bald-faced
lies. Ironically this omission probably makes their calculations more reliable
!
Because of the deficiencies in production data, much of which is often a
"state secret" at the reservoir level, they came up with different dates, like
"already yet" [ 2004 ] and "far away" [ 2032 per Exxon/Mobil ]. Having waded
through quite a few of these estimates, it is my professional opinion as an energy
economist that it is impossible to pinpoint the peak year with an acceptable
degree of accuracy. However, we can say that there is a 90% chance that an
unsurpassable peak in World production of crude oil will occur by 2020, if not
earlier.
Since this is only 12 years away and so well within the horizon of many
strategic planners, it behooves them to make contingency plans, at the very least.
>From their size, the "hidden" Alaska reserves [ if they are of the magnitude
alleged ] may push that fatal year a few more years into the future, but it is
my guess is that it will not get it outside the planning horizons of most
strategic planners. So again, at the very least, some serious contingency planning
is called for, even if you side with Cambridge Energy Research Associates,
Exxon/Mobil, the Energy Information and other perpetual optimists.
In addition, I would like to point out two factors which are usually omitted
in discussions of peak oil but which would tend to make the peak year come
sooner rather than later.
[1] The energy used to put a marketable liquid in a tank on the surface.
We have already mentioned the injection of material into aging reservoirs,
examples of which are Ghawar in Saudi Arabia and Cantrell in Mexico, already in
decline despite injection. In addition, there is the energy required to obtain
oil from unconventional sources, such as tar sands, which can run to the
equivalent of 35-45% of the potential energy in the marketable oil produced.
Once this energy consumption could be safely ignored. Now it cannot. Yet none
of it is deducted from published figures, either for reserves or for
production. So even if statistics for production and reserves of crude oil were all
accurate and honest [ which they are definitely not ] they would be seriously
overestimated, in terms of what is available for conversion into salable
products.
[2] The rising consumption of energy is oil-producing countries. Iran,
for example is already an importer of gasoline, because refinery expansion
cannot keep up with the increase in domestic demand ! And in Qatar, whose gas is
often seen as the "white knight" which will save oil consumers from their
folly, much of the projected increase in production is already committed to 15,000
luxury condominiums, an ammonia plant, a fertilizer plant, a steel plant and
so on.
So the matter of peak oil is a difficult one, but it is definitely not
"rubbish". An unsurpassable peak in World crude-oil production is coming. The only
question is when. Since the odds are that "when" is within the planning
horizons of most of the people who make investment and/or political decisions, it
makes sense for concerned parties to stop insulting other participants in the
discussion and do some serious contingency planning.
Sincerely. ###
