If you read some of the links I posted, the fundamentals of oil have changed dramatically in just the last year.
Fracking isn't going away with lower prices like most thought, it's now much more efficient than it was, and it gets more efficient every day.
The cost of pulling oil out of the ground here is now around $13 per barrel, vs around $11 per barrel in Saudi, not a huge difference and not enough to stop drilling.
Nobody is cutting back because if they do, they lose market share, hello $20 per barrel oil, with a ceiling of $60.
