Well at least we did until the price of oil dropped below $50 a barrel. I think IIRC they need somewhere around ~$70 a barrel to make a profit on Shale oil, tar sands etc. Any lower and they will shut things down and wait for a price recovery.
I see. I did not know this, and just spent some time reading a bit about the economics of shale oil (tight oil). I learned something, thanks!
