Biden's policies are wretched but have little to do with current production rates. I am a geologist. I could go into specifics, but there's spin both ways. Biden's policies will affect future production, not current. Much of the current malaise is due to rolling hedge policies that are just starting to burn off from covid. These are "insurance" banks place on production for lending in the oil & gas industry. Due to this, many companies have been budgeting within cash flow. Right now, many companies are upside-down on their hedge positions and not realizing the full price you hear on the news.

And no, Trump did not cause the big increase in oil production during his administration. That was just good timing. The industry had been researching and figuring out new ways to increase production in West Texas. I was a part of it. Before 2016, much was still unknown. After that, a land grab ensued. As part of the terms of an oil & gas lease, there is an expiration. If you drill on a lease, it will be held by production (and not expire). The run-up in production during Trump's administration was caused by companies (using debt) trying to secure as much of their leasehold as possible.
