Now we come to the completely false [or deliberately misleading] claim by Peak Oil shills that production from existing oil wells is "slowing down", thereby proving that the oil fields are "running dry". This is so wrong that it is almost breathtaking. Think of this slowing down process in the same way you might think of the engine oil in your automobile. The longer you run the engine, the higher the level of contaminates that get into the oil. The higher the level of contaminates, the higher the level of friction. Sooner or later you have something closely akin to glue coating your piston rings, and the performance of your engine declines accordingly. This is an inevitable mechanical process well known to all automobile owners.
Henry Ford and others managed to slow down the rate of contamination in engine oils by inventing the oil filter, through which the oil has to circulate each time it passes around inside the engine. A high percentage of the contaminates stick to the filter element, thereby allowing extra miles between oil changes, though heaven help the careless motorist who thinks he can get away without ever changing his clogged oil filter when recommended.
When oil is extracted from a producing formation underground, it flows out through pores in the reservoir rock, and then into the open borehole, from where it is transported to surface by the production tubing string. So by the very nature of the beast, the bottom section of the well is "open hole" which allows the oil to flow out in the first place, but because it is comprised of exposed and sometimes unstable rock, this open hole section is also continually subject to all manner of turbulence and various contaminates. For example, tiny quantities of super fine silt may exit through the pores but not continue to the surface with the oil, tumbling around in the turbulence instead, until the silt very slowly starts to block off the oil-producing pore throats. Yes, of course there are a variety of liners that can be used to slow down the contamination, but there is no such thing as a Henry Ford oil filter 10,000 feet underground.
The inevitable result of this is that over time, the initial production rate of the well will slowly decline, a hard fact known to every exploration oilman in the business. However, this is certainly not an indication that the oil field itself is becoming depleted, proved thousands of times by offset wells drilled later into the same reservoir. Any new well comes on stream at the original production rate of its older cousins, because it has not yet had time to build up a thin layer of contaminates across the open hole. Though as we shall see it is possible to "do an oil change" on a producing well and bring it back to full production, this is extremely expensive, and rarely used in the west.
Look at a simple example: Say we have a small oil field in Iraq with ten wells that each started out in life producing 10,000 barrels of oil per day. Fine, for a known investment we are producing 100,000 barrels of oil per day from our small field, at least for a while. Five years later contamination may have slowed our overall production down by ten percent to 90,000 barrels per day. So we are now faced with a choice: either "do an oil change" on all ten existing wells at vast expense and down time, or simply drill one additional well into the same reservoir, thereby restoring our daily production to 100,000 barrels with the minimum of fuss. Take my word for it, ninety-nine percent of onshore producers will simply drill the extra well.
Naturally there are times and places where this simple process is not an option, for example on a huge and very expensive offshore platform, which may have only 24 drilling 'slots', all of which have been used up. To restore your overall production after five years you can either build another giant platform next door for two billion dollars, or "do an oil change" on each of your existing 24 wells, one at a time. Clearly this time you are forced to carry out the time consuming business of restoring the open hole section at the bottom of the well to its old pristine condition, before various contaminates started to slow down your production rate.
For this task you first pull the production tubing out of the hole, and then run back in with a drill string, to which is attached an underreamer as shown in the pictures above. When the reamer is directly opposite the top of the open hole producing section, the drill string is rotated to the right and the blades fly out under centrifugal force to a distance preset by you before lowering the tool into the hole. The objective is to cut away the contaminated face of the well to a depth you consider will once again expose pristine producing pores. As the spinning underreamer is slowly lowered, it enlarges the size of the hole, with the contaminated debris cut away and flushed back to surface by the drilling fluid. Hey presto, you have a new oil well, and it only cost one or two million dollars to restore…
Remember I said this process is rarely used in the west, which is true, but it is not true of Russia, where the objective for many years has been to dominate global oil supply by continual investment. With no shareholders holding out their grubby little hands for a wad of pocket money every month, the Russian oil industry managed to surge ahead, underreaming thousands of its older existing onshore wells in less than ten years. Then along came Wall Street asset Mikhail Khodorkovsky, who fraudulently got his hands on Yukos oil for a mere fraction of its value, and was on the point of selling the entire outfit to the American multinationals when Vladimir Putin had him hauled off his private jet somewhere in Siberia. So Wall Street was finally 'cheated' of its very own 'free' Russian oil, and poor old Mikhail had better get used to the taste of prison food.
To recap, 'Peak Oil' claims that because today we only find one barrel of oil for every four that we use, world oil reserves are running out. Completely misleading propaganda. as the Russians [and the CIA] know perfectly well, reserves of oil in the mantle of the earth are infinite. 'Peak Oil' also claims that we will shortly be unable to pump sufficient oil out of the ground to keep up with demand. Completely misleading propaganda again. We could drill more wells, but Wall Street cannot afford to pay for them, and never intended to, at least not while it still believed conquest and eternal occupation of the Middle East was a realistic possibility.
Professor Poleo makes it quite clear which direction the west needs to go in if it is to survive in the long term, and that is to follow Russia's example by sharply reducing domestic consumption. Back in 1990 America was using around 6 million barrels per day compared to Russia's 8.4 million, but how things have changed since then. Thirteen years later in 2003, American consumption was up to 9 million, while Russian consumption had been reduced to a mere 3.2 million. A few billion folk over there in America might like to walk around their houses and switch off any electrical appliances they don't actually need. Believe me, I can almost hear the oil surging through the pipelines in New York, and I live more than 12,000 miles away in Australia.
In closing I would like to pass on my greetings and thanks to the cheerful Russian drillers and scientists I had the pleasure of working with at Bodra #3 in West Bengal, without whose expertise we might all be dead today, as a direct consequence of repeated American sabotage attempts on the high pressure well. My thanks also to the Moscow Drilling Institute for the unrestricted flow of information and documents on ultra deep oil production technology, without which I could not have written this report.
