dido writes "Princeton University geology Professor Kenneth Deffeyes has been studying world petroleum production data and has come to the conclusion that the world hit peak oil last December 16, 2005. If he is correct, total world oil production will never surpass what was produced last December. From the article: 'Compared to 2004, world oil production was up 0.8 percent in 2005, nowhere near enough to compensate for a demand rise of roughly 3 percent. The high prices did not bring much additional oil out of the ground. Most oil-producing countries are in decline."

I've seen this simulated, it isn't pretty. (Score:5, Interesting)
I remember in college a geologist was invited to demonstrate a "resource simulator" for our class. By today's standards it would be considered extremely crude (this was after all, in 1978), (wow, weird unintentional pun).
The simulation was basically a giant video game with a simple graphical display of the world's known and projected resources including but not limited to:
About 20 students in the class were given controllers, each to (again, crudely) simulate usage and comsumption patterns of all of these resources. Also, some students had controllers allowing them to spend resources to explore for MORE resources.
At the time, and years subsequent that demo stayed with me -- it left an indelible image of what could and probably would be.
The results? Basically, no matter what the students did to conserve, and what they did to increase the resources, the "world" pretty much always ran out of fuel and resources by the year 2020. At the time that seemed pretty far away and I don't think many people felt the need to care. Maybe that time has come.
Another interesting piece of the simulation: there were those students who pointed out these "estimates" of known and expected future discoveries of resources were just that, "estimates". The geologist obliged, and let the students rerun the simulations with a magnitude of latitude, i.e., ten times the estimated resources were allocated! The results then?, about an additional 10 to 20 years of resources before they ran out.
Note: the results (we ran many different trials) weren't ALWAYS about running out of oil and petroleum. On a few occasions there were severe food and water crises. A very interesting lesson.

So he wrote a program to demonstate the effect of exponential growth, and modeled some lame "conserve" and "research" options that didn't really effect the growth rate. It was a simulation designed to always come to that conclusion. Big surprise that it always led to that conclusion, huh?
Being college I hope somebody spoke up and challenged his assumptions, I also recall models that projected the population continuing to grow exponentially, though the reality has been far from that. Yes resources are being consumed far faster than they are being generated, but at the same time technology is moving fatser than ever too. My 295hp car just got 28 mpg on a 3 hour trip today, in 1978 that car would have gotten about 6-12mpg (since there were no 295 hp new cars in 1978, we'll have to estimate). One thing to keep in mind is that we DO have renewable sources of energy, and technology continues to lower the production costs of these while the non-renewable sources will continue to rise. At some point the two lines cross and we'll switch in a big way. The USA is real good at solving these problems.

Anyone can rub together two brain cells and write a report that glosses over market realities with some sensationalist simplifications.
Basic economics indicates that that the market can fall behind reality for several years.

Which oil peak are we on? Deja vu! (Score:5, Informative)
In 1855, an advertisement for Kier's Rock Oil advised consumers to "hurry, before this wonderful product is depleted from Nature's laboratory."
In 1874, the state geologist of Pennsylvania, the nation's leading oil-producing state, estimated that only enough U.S. oil remained to keep the nation's kerosene lamps burning for four years.
In May 1920, the U.S. Geological Survey announced that the world's total endowment of oil amounted to 60 billion barrels.
In 1950, geologists estimated the world's total oil endowment at around 600 billion barrels.
From 1970 through 1990, their estimates increased to between 1,500 and 2,000 billion barrels.
In 1994, the U.S. Geological Survey raised the estimate to 2,400 billion barrels, and their most recent estimate (2000) was of a 3,000-billion-barrel endowment.
By the year 2000, a total of 900 billion barrels of oil had been produced. Total world oil production in 2000 was 25 billion barrels. If world oil consumption continues to increase at an average rate of 1.4 percent a year, and no further resources are discovered, the world's oil supply will not be exhausted until the year 2056.
The estimates above do not include unconventional oil resources. Conventional oil refers to oil that is pumped out of the ground with minimal processing; unconventional oil resources consist largely of tar sands and oil shales that require processing to extract liquid petroleum. Unconventional oil resources are very large. In the future, new technologies that allow extraction of these unconventional resources likely will increase the world's reserves.
Oil production from tar sands in Canada and South America would add about 600 billion barrels to the world's supply.
Rocks found in the three western states of Colorado, Utah and Wyoming alone contain 1,500 billion barrels of oil.
Worldwide, the oil-shale resource base could easily be as large as 14,000 billion barrels -- more than 500 years of oil supply at year 2000 production rates.
Unconventional oil resources are more expensive to extract and produce, but we can expect production costs to drop with time as improved technologies increase efficiency.
With every passing year it becomes possible to exploit oil resources that could not have been recovered with old technologies. The first American oil well drilled in 1859 by Colonel Edwin Drake in Titusville, Pa. -- which was actually drilled by a local blacksmith known as Uncle Billy Smith -- reached a total depth of 69 feet (21 meters).
Today's drilling technology allows the completion of wells up to 30,000 feet (9,144 meters) deep.
The vast petroleum resources of the world's submerged continental margins are accessible from offshore platforms that allow drilling in water depths to 9,000 feet (2,743 meters).
The amount of oil recoverable from a single well has greatly increased because new technologies allow the boring of multiple horizontal shafts from a single vertical shaft.
Four-dimensional seismic imaging enables engineers and geologists to see a subsurface petroleum reservoir drain over months to years, allowing them to increase the efficiency of its recovery.
New techniques and new technology have increased the efficiency of oil exploration. The success rate for exploratory petroleum wells has increased 50 percent over the past decade, according to energy economist Michael C. Lynch.
A question I asked Kenneth Deffeyes (Score:5, Insightful)
Today there was a talk in Beckman Auditorium by Kenneth Deffeyes [princeton.edu], Princeton professor emeritus and author of one of the more popular books on that ever-popular meme, peak oil. He discussed his belief that we had hit peak oil sometime around this past Thanksgiving, and that oil prices are going to fluctuate wildly and rise in the next 5 years of so.
During the Q&A period I went up to the microphone and asked the following: During your talk you briefly mentioned the futures market. Currently on the oil futures market, you can purchase a contract for a barrel of oil to be delivered in, say, the year 2010 or 2011 which is actually cheaper than a barrel of oil today. What are your thoughts on why this is the case?
In his response, he had mentioned that he had been asked a similar question after he gave his talk at Merrill Lynch, basically: "If you really think oil prices are going to rise, why don't you put your money where your mouth is and buy up futures contracts?" He said to them that he wasn't too knowledgeable about futures contracts, and afterwards read up on them a little and found some of their intricacies bewildering. He said that he would want to purchase futures options for the coming few years, due to the extreme price fluctuations he expects, followed by regular futures in the longer term.
I'm not sure I bought his answer. Although I'm not sure about how far ahead one can purchase futures options, regular futures can definitely be purchased for 2011 [tradingcharts.com], which should be well into the period of soaring prices he predicts.
Gasoline/Fuel Oils are only part of oil use, (Score:5, Insightful)
The first thing the govt. should do is reevaluate the way it calculates fuel economy. The current system is grossly innaccurate, and doesn't give consumers a true picture of the gas mileage they can expect. Consumer Reports had an article about this and the auto industry rep. basically said that the auto companies know how the govt. tests, and optomizes their vehicles for the test (gear ratio tweaking, using prototype vehicles, etc.). Changing the test methods would give consumers more accurate information so they can make a more informed decision.
The second thing the govt. could do is raise the minimum required fuel economy and make light trucks subject to the gas guzzler tax. I work at a Dodge dealership and the fuel economy of new vehicles is attrocious. A new durango gets 14-18 mpg and pays no gas guzzler tax. A station wagon that got similar mileage would have a several thousand dollar tax associated with it. Treat SUVs like the cars that they are replacing and you will find that fewer people will buy one.
The third thing that the govt. and EPA could do to help is to standardize fuel grades. Under the current system, refiners have to produce something like 60-70 different blends to comply with various state enviromental regs. The govt. could reduce this clusterfuck by having perhaps 2 or 3 different blends; one blend for urban/enviromentally sensitive (pacific northwest, etc.) areas, and one blend for areas where pollution isn't as big of a problem. Current refineries in the US are running at or above full capacity, and this would help ease that situation, and allow oil companies to put current resources to better use.
In addition to the step above, I firmly believe that the govt. should raise minimum octane ratings for gasoline. If the US had higher octane ratings, we could use higher compression ratings, and turbochargers would be a lot more effective, allowing smaller displacement engines (like most japanese cars have) to produce the same horsepower as a larger naturally aspirated engine but with increased fuel economy.
Obviously, these aren't complete solutions to Americas oil addiction, but they are things that would help.
P.S. while writing this post, I came across an interesting ad [sierraclub.org] that the sierra club ran in the new york times on Ford's 100th birthday. 100 years of "progress" indeed.

I really, really, really, wish that was the case. But I'm afraid it just isn't. A lot of people are living in fantasy land right now and assuming that any spike in oil prices is going to be like the 1970s. But after a point, it won't just come back down. Extrapolation works rather well in this case because there's no real reason to believe that the world's oil consumption is going to dramatically decrease, and considering that oil-producing countries are basically operating on the same fields they always have been (because there just aren't very many new ones). Oil price fluctuates because of the rest of the supply chain, not because there are new wells being drilled and others shut down all the time. Relatively speaking, it's a fairly predictable economy.

Re:Why the peak? (Score:5, Informative)
At some point, the oil is not under so much pressure and doesn't squirt out so much. Perhaps the oil men need to drill deeper, or sideways, or use other fancy techniques and so the take per day is reduced. This may go on for some time, forming a flattening of the peak at the top. Maybe. More often, and especially over the last 20 - 30 years, the field is run flat out for as long as possible, so production stops more quickly.
As production dwindles, other techniques come into play, like forcing in seawater under pressure to push the oil out (as in Saudi Arabia), and many of these can damage the field, reducing the long term extraction total in favour for a higher extraction rate today. As time goes on it becomes harder and more expensive to extract the oil (diminishing returns) and eventually it's just not worth it, so the field is closed down.
This is the idea, there's a curve for every well and every field. If you add all the curves together, then you get one big curve, whith "Hubbert's Peak" in teh middle (the geologist who first noticed the production bell curve).
Now the problem isn't that suddenly all the oil's gone when we wake up next tuesday, it's that this month/year we produced less than last month/year, but -- and this is the problem -- we use MORE than last month/year. Demand is growing faster than ever before, just at the time when the supply is starting to drop off. This causes price increases and countries can be expected to squabble over an oil supply which continues to become smaller.
As an aside, people like to say that "They've been prediciting this for years, it's never happened before so whay should it happen now?" The answer is that it's been predicted to happen now. I have a text book from 1954 (that's over 50 years ago) which predicted that demand would exceed supply around the year 2000 -- and you could argue that we are later that this because of improved extraction (not production, you extract oil) technology and because of a drop in consumption from teh late 70's oil shocks.
The supply/demand gap is a political and economic (and military?) problem in itself -- whether or not there's still enough oil to make all the toy for the happy meals might be a problem, but even if it isn't, the gap between supply and demand is a big enough problem all by itself.
peakoil.net is where to go to explore the argument in detail -- it's not a greenie thing, it's not a anti-american thing, it's to do with geology and chemistry. Beware of people who quote reserve figures, not only to countries lie outright about the figures, but quoting reserves is a potential -- you can't ever get every single barrel out of the ground and leave dry dust behind, lots remains and will never be extracted. As for scientists saving us, bear in mind that the warnings of peak and the warnings that alternatives like ethanol are almost useless are coming from eminent, experienced talented scientists. Science is not magic, if we're using too many joules per day then you can't just create it. I'm delighted to discuss why every alternative is doomed, try me at drose@dtlm.homelinux.net and I'll explain why I reckon population will halved in the next fifty years.

Oil sands reality (Score:5, Informative)
But getting it out is tough. First, read this fact sheet from the Athabasca Oil Sands Developers. [oilsands.cc] Current production is about 1 million barrels/day. This should be up to 2 million per day by 2010, and 4 million per day in 2015. That's about where the Ghawar field in Saudi Arabia is now. If everything works out right, Athabasca might be able to keep up with the decline of Middle East oil fields. (Incidentally, production in Kuwait peaked last November, somewhat to the surprise of the Kuwaitis.)
Money is being spent on oil sands development at increasing rates. In 1995, the forecast was CN$5.7 billion over 25 years. Spending is now at CN$9 billion per year and climbing. Payback is slow; more than a decade. This isn't a bonanza business, although at $60 a barrel, it's looking better than it ever did before. The oil sands industry got clobbered when oil prices dropped in the early 1990s. Investors still worry about that, since the actual cost of extracting Saudi oil is somewhere around $3/bbl.
Extraction from oil sands is a big job. The settling ponds are visible from orbit. Take a look at 57N 111.6W. Those aren't lakes. Those are man-made open pit mines and settling ponds. This is a far more expensive process than drilling and pumping. A ton of sand yields a barrel of oil. You don't even get oil out; you get asphalt, which has to be cracked down to crude oil, then to gasoline. Costs are running around $30/barrel.
Worse, with current technology, natural gas is used to make the steam to separate the oil from the sand. This is currently a substantial fraction of Canada's natural gas consumption. When natural gas prices go up, so does the cost of oil from oil sands. And it's a wasteful thing to do with natural gas. There's a project underway [nexeninc.com] to build an oil-sands project that's self-fueling, using its own product to generate steam, but it won't be running until 2007. If that project doesn't work out, oil sands are in big trouble.
If you want a job as a heavy equipment operator, mechanic, or welder, head for Fort McMurray, Alberta. They're hiring. But apartment occupancy is at 100%, so you may end up in worker barracks.
So that's a more realistic view of Athabasca oil. It's real, but it's not a miracle.
