If we leave all the tight oil in the ground, we will be short about 3 million barrels a day. That degree of shortfall would cause a massive price spike. But consumers couldn't possibly afford that. If consumers could actually afford super high priced oil, why aren't they doing it now?Who knows? And it doesn't matter. Until the price goes up, the tight oil will just sit there and then we can extract it if and when we need it. Thermodynamics is not going to make it somehow harder, or less worthwhile, to extract if we leave it for a bit. There's no penalty for taking the cheapest oil out first.
How, exactly, can the current price of oil double or triple and still be affordable to oil consumers?
And if the oil price cannot rise that much, how will we ever get the tight oil out of the ground?
