Good news about oil, but for our grandkids – not us
A comment on this site said “The data really do speak for themselves if given a chance.” Unfortunately this is not so. Change can disorient us, making it difficult to clearly observe and analyze the situation. Lawrence Solomon demonstrates this for us in his article about peak oil. Too many people make his mistakes, and we will pay dearly as a result.
“Abundant energy will power future growth”, Lawrence Solomon, op-ed in Canada’s Financial Post, 12 July 2008 — Opening:
Up! Up! Up! The world is consuming more and more energy and, as if by miracle, the amount left to consume grows ever higher. Never before in human history has energy been accessible in greater abundance and in more regions, never before has mankind had more energy options and faced a brighter energy future.
Everything Solomon says about oil reserves is correct, yet his conclusions are almost totally wrong. How can this be? He commits one of the classic analytical errors, confusing stocks and flows (e.g., the annual fiscal deficit vs the total accumulated debt). He sees the problem as a lack of reserves (stocks), when it is a shortage of production (flows). It is a common mistake, despite countless explanations in the the peak oil literature that Peak Oil is not about running out of oil. Our great-grandchildren will still be pumping oil — just less of it.
Peak oil means shifting from conventional to unconventional reserves
Peak oil is a transitional phase, from conventional oil sources to unconventional sources – non-flowing deposits (Bakken Formation in the US), polar, deep sea (new finds off Brazil), heavy oil (Venezuela), bitumen (Canadian oil sands), kerogen (US oil shale), and coal (converting it into a liquid fuel). The aggregate reserves of these are immense. But they are not directly comparable to conventional reserves in the way Solomon does. Unconventional sources differ from conventional petroleum in two ways.
- Their extraction costs — either initial capital outlays or operating costs (or both) — are usually far higher.
- Their production flows are lower. Nothing like the massive flows from the great fields of Texas and Saudi Arabian.
For example, by 2020 Canada’s bitumen mining might produce 5 million barrels/day — after tens of billions of capital investments, with incalculable costs to Alberta’s environment (much of it will look like the moon). That assumes sufficient water and natural gas inputs, both of which might be insufficient (nukes have been suggested as alternatives to the nat gas). But that will not nearly offset the natural depletion of other N. American fields, let alone replace the peaking of the supergiant fields like Cantarell in Mexico or Gwahir in Saudi Arabia.
Another distinction between conventional and unconventional petroleum: the latter often require far larger inputs of energy for their extraction and refining than conventional sources. For example: heavy oil, bitumen, kerogen — all must be mined, heated, and hydrogenated to produce useful products.
Unconventional sources are valuable, and will increasingly represent the remaining global oil reserves. But neither their flows nor costs can be compared to the ample and cheap conventional fields now being sucked dry. That is the missing element in their euphoric stories.
Two briefer explanations
All unconventional oil needs time to be produced in great quantity, no matter how much effort is made. It is not possible to have a baby in a month with nine women.
— Jean Laherrere, A-team oil expert (from a DOE internal energy briefing, August 2007)
An analogous situation between rate and “reserve” appears with water. The planet’s surface is covered with it (approximately 71%) and to great depths, yet we have “water shortages.” If the same approach of those advocating large oil reserves reserves meaning “no problem” was applied to water, how could we ever have a water shortage? However, it’s not in a usable form and much effort has to be expended to treat it for suitable use.

Solomon’s second error
“But most of the world remains unexplored — the interiors of Africa, Asia and South America have seen relatively little oil exploration. Oil exploration in the oceans, too, is in its infancy.
This almost qualifies as an urban legend. While there are certainly many yet undiscovered conventional oil fields, it is unlikely there are many giants — let alone supergiants — to be found. And hundreds of small fields must be found to replace fields now in rapid decline, like Cantarell in Mexico and in the North Sea.
Update: magical thinking about energy
Can shale oil be developed economically? At today’s prices, of course.

Like Solomon’s op-ed, this is factually right — but misleading. We do not have a commercially-proven method of extracting oil from “shale oil” (kerogen). Commercially-proven means more than economics. The engineering must work reliably on a large-scale, with acceptable environmental impacts and available inputs (esp water). We are not yet there. From Wikipedia (an excellent article, with links to the sources used);
There are hundreds of patents for oil shale retorting technologies. However, only a few dozen have been tested in a pilot plant (with capacity 1 to 10 tonnes of oil shale per hour) and less than ten technologies have been tested at a demonstration scale (40 to 400 tonnes per hour). As of 2008, only four technologies are in commercial use, namely Kiviter, Galoter, Fushun, and Petrosix.
Once the engineering is proven — construction and operation of a modern pilot plant — it will take a decade to scale up production (building progressively larger plants) to a meaningful level. So “shale oil” might be part of a solution, but time and money will be required to find out. Then more time to put this technology into play. It’s not magic.
