Is that the reason, though? I heard on the news (unfortunately don't remember where) that oil production decreased when people were driving less, then as people resumed driving, production didn't increase as fast as demand.

Which would make sense to me because there have been a ton of situations where some pandemic event has caused some previously generally stable thing to shift (up or down) to some new level, then we have chaos as other things try to adapt and find a new equilibrium. Then when the pandemic stops forcing that thing to an unusual level, it springs back toward its normal level, and again other things take time to adapt and find an equilibrium.

So actually we seem to get two edge-triggered periods of chaos where something shifts from value V1 to V2 (that's one edge trigger) and then shifts back from V2 to V1-ish (the other edge trigger).

And if you look at crude oil prices over the last few years, they were lower during 2020 than in previous years. Now they are higher. So that fits the pattern I'm describing.
