“In my home state of Colorado, hundreds of wells have been abandoned”
If they were in the process of drilling they can stop and let them sit.
If they have been finished and are in production, they simply can not stop pumping some of those wells or they will loose the pressure and wont be able to bring that well back into production.
For those pressure wells its pump no matter what.
I remember the early late 1970s when the oil embargoes sent the price of oil sky high! The government decided the oil companies could not charge the higher price than what the oil well originally produced.
As a result, the oil well was shut down, and a new well drilled beside it in which they could charge the higher price as it was a “new” well.
