Ah, the folly of operating in artificially defined boundaries drawn by engineers with a linear mindset on a Holy Grail quest for increased oil profits! The world they manufacture is so perfect that they are actually able to convince skeptics and environmentalists that they can pull oil out of oil shale in a manner that actually creates more energy than is expended.
A least that is what Shell oil would have us all believe. They just can't leave the world's biggest deposit of oil alone, even if it is locked up in rocks underlying Utah, Wyoming and Colorado. Even though the oil companies tried to do this back in the 1970S and failed miserably. But this time Shell has new technology (that marvelous silver bullet to save us all) that is going to extract this liquid gold in an environmentally safe process providing that favorite drug of overly consumptive Americans--cheap oil.
Here's how Shell plans to do it. They are going to drill giant holes in the ground, lower in huge electric heaters and heat the rocks until they ooze oil in a viscosity that can be pumped out. Then, to protect the ground water Shell will drill another set of holes surrounding the heater holes where they will insert electric refrigeration systems to freeze the water, forming an ice wall so the flowing oil can't get out and pollute anything.
Just like the days of the Synfuels project during the Carter Administration these same oil companies are trying to get us all to believe that they can extract more energy out of the ground then they have to use getting it out. In this case "3.5 units of energy for every 1 unit used in production." But the question really is what constitutes "production?"
These folks are much more sophisticated about terminology now then they were back in the 70S. They throw around words such as "life-cycle analysis" to give the impression that they have looked at the whole system and have taking everything into consideration. But let's just pull at the edges of their study boundary a bit more to see where this oily Ponzi Scheme begins to erode.
First, the energy needed to heat the rocks and then freeze the water will require enormous amounts of electricity. A report estimates that for "each 100,000 barrels produced daily it would require about 1.2 gigawatts of electric-generating capacity." That is more than the largest power plant in Colorado today!
Second, the fuel used to generate this energy would most likely be coal. How much energy is expended mining, processing, transporting and fueling these coal fired power plants? Has this been factored into the equation for determining recoverable energy from oil shale?
Third, if this process for extracting oil from oil shale requires the construction of new power plants, what is the energy expended in building these plants? How much energy is used to make the materials, transport the materials and then erect the plants? This has not been factored into the energy availability equation at all.
And finally, with all of the evidence of global warming and climate change linked to the burning of fossil fuels it is simply an oil addict's insanity to burn coal to generate electricity to heat rocks to 700 degrees to extract oil to burn for energy all the while generating megatons of life destroying CO2.
If Shell's plans succeed and their minions in Congress push through legislation supporting and subsidizing this petroleum psychosis we won't be able to breath easier because of lessening our dependence on Mid-East oil.
We probably won't be breathing at all.
