I've always wondered about the reasoning behind how crude oil deposits work in the game.

Why did the developers choose to make oil fields produce indefinitely at a reduced rate instead of treating them like iron or copper deposits that eventually run out?

I'm just curious about the design decision and whether there's a specific gameplay reason for it.

#1 is is actually based on how real oil fields operate. We can't actually pump every last drop from a given borehole because as the oil is extracted, the pressure in the reservoir decreases. At some point, you get only tiny amounts of oil out because your pump can only suck so hard.

#2 is that implementing a semi-realistic system like this adds variety to the gameplay. It means you have to make a judgement during the game when to explore for more oil, and whether to dismantle an unproductive outpost. It's not a binary indicator when the right time to do that is.
