You got that right, no point of shutting down a well that already producing, profitable, and the money has already been sunk into.
I don’t think there is any talk of shutting down wells at today’s prices.
But some of the wells that would get drilled next year will be put on hold. While that happens, the flowing wells continue to slide lower on the production curve. If drilling slows down enough, the total US production rate will fall. It will certainly slow down the growth rate at $75 versus $100 over time.
