The model doesn't fail inmediately after having consumed all the resources, because we usually don't get to that point: at certain point the costs are higher but the price of the goods hasn't improved (because somebody else has replaced the goods with technology or has started to exploit cheaper to extract resources from somewhere else), so you just drop the still available resources and get your money to other investments.

That's what's happening right now in Vaca Muerta, Argentina (which is similar to Permium in Texas).

Well, I'm not going to the end of the story in Earth resources, when everything has been depleted, but I suspect I would be rushing conclusions in that case: (even) current technology still holds some good cards to fastly add lots of new resources to our planetary whole stuff.
