I have had peak oil on my mind lately. Probably because I find it interesting for speculation but, I also find it interesting to read what others have to say on the subject. It has become a topic of discussion on the main stream media lately and, like most things they discuss, the information that they present is either just outright wrong or highly distorted. I wonder if our class room teachers do a better job of explaining things than the knuckle heads in the media. Part of the problem with the main stream media, MSM, is they all have a bias and simply cannot tell you anything without attempting to make Obama look great or make him look stupid. It all depends on politics. Why is it that everything has to be politicized? I mean things like global warming and peak oil really should be scientific subjects and presented as matter of fact. What I mean is that facts should be presented without the politics. Dream on.
I’m drifting again. Back to peak oil.
If you open a text book on oil exploration you will almost certainly be presented with a graphic image that attempts to show the cross section of the earth under an oil well. So far, every one of these images that I have seen has it wrong. A casual reader will come away from the book with an image of a pool of liquid oil somewhere below the surface trapped above a salt dome. I mean a literal pool. You know something you could swim in. I do not know why it is always represented that way because there is no such thing. Oil is not in pools under the surface. Oil is distributed throughout porous rock layers. Oil must move through the pores of the rock in order to get to the well and then to the surface.
Keep that thought in mind for a second.
I will now turn your attention to Boulder Dam. Behind it is a huge reservoir of water from the Colorado River. There is enough water behind the dam to supply Las Vegas for a hundred years. OK, now we are going to turn off the water flowing out of the dam and in place of the normal discharge, we will drill a hole through the bottom of the dam into the lake behind it and that hole will be 1 inch in diameter. So, here is the question. How many people can you keep alive given that there is enough water behind the dam to supply everyone in Las Vegas for 100 years IF the only way you can get at the water is through the 1 inch hole?
There you have it. That is what the MSM always seems to get wrong. You hear them say things like we have enough oil beneath the earth to supply mankind for 100 years. It makes absolutely no difference whether there is enough to last 100 years or 10,000 years. The only thing that matters is how fast you can get it out of the ground. If you cannot extract the oil as fast as it is needed you have a supply vs. demand imbalance. If you only have a 1 inch hole then you might have a problem.
The MSM forgets that it is not the quantity of oil that is left but the rate at which it can be extracted that is important.
The rate at which oil can be extracted from an oil well depends on the oil pressure and the diameter of the pores in the rock in which it resides. When the first well is drilled into a new oil field, the pressure is great and the oil comes out of the well rapidly. As more wells are drilled into the field and as oil is extracted, the flow rate of the wells decreases over time. As more and more wells are drilled into the field a curious thing happens. Basically, if you double the number of wells then, the flow rate at all the wells is cut in half. If you quadruple the number of wells then the flow rate at all of them is reduced by a factor of 4. At some point no matter what you do, you cannot increase the total extraction rate for oil from that oil field. When that happens, you have reached “peak oil”. Peak oil means peak oil extraction rate.
There are methods for increasing the flow rate but, these enhanced extraction methods only cause the oil field to be drained quicker and are expensive to employ. Mexico has the third largest oil field in the world and it passed it peak production rate in 1999. It has been in decline ever since. All of the latest enhanced extraction methods have been applied to that oil field. It is expected to stop producing oil completely within 7 years. In fact, the majority of oil fields in the world are past peak and are in terminal decline. They may have enough oil to last 100 years but they have reached maximum production and each year that goes by they produce less and less oil. The entire world has already reached peak oil and it did so many years ago. No one will tell you that on the evening news. Now I have to be careful here. What I mean is EXISTING oil wells combined are producing less and less oil every year. The amount of oil available from EXISTING oil wells is decreasing at a rate of about 4% per year. If nothing is done the production rate will accelerate and in 10 years or so the production rate is expected to be about 7% per year.
So, if we are to continue to produce oil sufficient to meet the needs of the world then, we must be actively looking for new oil to take up the slack. The oil companies have been successful at this and for the last 5 years the worldwide oil production rate has remained almost constant. But, the worldwide total production rate has NOT increased. To do that we would need to find even more oil. And to do that oil companies are now drilling wells in the deep ocean to depths approaching 30,000 ft; as deep as Mt. Everest is high!!!
So, when the MSM talks about peak oil they really mean the day when the new oil discoveries are no longer sufficient to offset the declining production rate of existing oil wells. . When the supply of oil drops below the demand, you can expect the price of oil to sky rocket. That is what all the hubbub is about. And, of course, it has become very political.
But, that is not even the biggest problem or even the first oil problem that we will face regarding the worldwide oil supply. There is another problem that is on its way and is already on our door step. This problem is one we will have to deal with long before peak oil becomes an issue.
Recall that I said that Mexico has the third largest oil field in the world and that it will be dry in 7 years? Well, in about three years, the oil consumption inside Mexico will increase to the point that Mexico will not have any oil to export any way. They will have oil but none to sell us. And, as the oil producing countries get richer and richer they want air conditioning systems, cars, electricity and all the things that oil is used for. And they want more and more of it every year. So, while the oil production rate from oil wells is decreasing at only 4% per year, the oil consumption rate of the oil producing countries is increasing at about that rate as well. And this means that the oil available for export is decreasing at about 6% per year. The world needs to find and bring on like new oil fields to replace all of the loss. As oil producing countries see their reserves decline, they are torn between limiting exports to preserve their supply and increasing exports to obtain much needed cash. Eventually, they will all stop exporting.
Here in America, we have an even larger problem. We already use 25% of all the oil that is produced every year. Developing countries like China and India are getting rich and they want cars and air conditioners and electricity and all the stuff that is made from oil. As they consume more there will be less for us. IF the demand exceeds the supply you can be sure that prices will escalate and that will price a lot of people out.
