During the heart of the pandemic you'll remember oil producers tried to keep it going, but filled all storage vessels on earth until they ended up with -$39 spot prices because storage was so short you had to pay someone to take delivery and store it. That caused producers to not only cap wells, but quit starting new wells.
Think of shale fracking wells as your dinger and the oil is your pee after drinking 5-6 of those miller lites in your pool. When you hop out to finally take a leak, you can initially shoot a stream over the neighbors fence. But soon it's starts to lose strength and after enough time has passed your just trickling out at an annoying level that's too much to stop, but it would take 30 seconds to fill up a shot glass. That's a fracking well.
So most of the big production is from brand new wells. So uncapping the old wells helps, but the real volume is in drilling a whole bunch of new ones with the power stream. But, much like everything else that shutdown suddenly, they destroyed their supply chain. Fracking sand and labor are the big ones. It will take years if ever to recover the damage done in a few months.
Another factor is they were drilling so fast pre pandemic just to stay alive. Prices were so low that they had to max out production. But the resource is limited. If they were able to get back to 2019-2020 they would tap the entire Permian basin within 5 years. Keeping at the current track might give them 10-15 years.
Here are some estimates of how much is left in current known inventory for frackers at current rates and after a 15% increase in production.
EOG
Current = 11 years
+15% = 4.4 years
Continental
Current = 11 years
+15% = 3 years
Devon
Current = 9 years
+15% = 2.2 years
Great article laying it all out, but I summarized since it's behind paywall most likely.

Ultimately for multiple reasons, don't expect to see big upticks in US production in the very near future. The frackers need time to explore new fields.
