 This simple diagram is meant to represent the positive feedback mechanism that we've put into the model So if you imagine that we begin with a production increase, that's the initial change Let's say something happens and we increase production That is going to cause the proven reserves to decrease right because production drains that reservoir So as that goes down the commodity becomes more scarce and because of that the price goes up So that's another effect here It's triggered by the production increase and as the price is increased that will then encourage us to do even more to try to Produce more of the oil that's out there. It's it's an incentive to produce more oil So that leads to an increase in production again So the initial change that that began this Was the production increase and that has end up triggering a series of responses in the model that lead to a further Increase in price and so when that happens, this is called a positive feedback mechanism It's kind of like a cause and effect loop, right? So here's a cause it makes an effect and makes an effect makes another effect It comes back on that cause and and enhances it So that's going to really change the way that this model behaves
