>There is another way in which oil & gas fields are re-charged -- via the biogenic production of oil & gas. But biogenic production via geologic heat and pressure is generally a much slower method of re-charging than Gold's abiogenic method. But it inevitably occurs all the same. Biogenic oil is a renewable resource, but it is renewable on a different time scale than humans generally use. >And yet, there is a way in which biogenic oil can "rapidly" recharge a depleted oil field. In the case of multiple communicating oil reservoirs at different depths, heat, and pressure, a deeper biogenic reservoir could re-fill a more superficial reservoir at variable rates, depending upon a number of factors. Oil & gas migrate upwardly, when given the opportunity. In this case, instead of "turtles all the way down," it is "oil & gas reservoirs all the way down." https://oilprice.com/Energy/Energy-General/Are-Oil-Wells-Recharging-Themselves.html [Geochemist Says Oil Fields May Be Refilled Naturally](https://www.nytimes.com/1995/09/26/science/geochemist-says-oil-fieldsmay-be-refilled-naturally.html) I think the idea that oil is limited is a fear manipulation tactic. Like saying wood is limited. All we have to do is grow more trees.
