You should recognize, that while they may go bust, the production is not going to be idled.
Even if bankrupt, someone will buy every producing well for dimes in place of dollars and keep that oil flowing.
The Bust just limits the new wells drilled. The old wells decline in production over time, but they don't stop because oil falls to $50.
Ping me when you find a wellhead selling for dimes on the dollar, please.
