Simple mod that gives infinite resource. For those who don't want to keep moving resource gatherers.
When an ore or oil well depletes, this mod tops it up to about 4billion units. So your miners/pumpjacks never run out.
For oil wells, it might take a while to deplete but once depleted it will be refilled and then your pumpjack will work at 140+k/s.
High performance. It only gets triggered when a resource depletes. No timers or per-tick.
No after-effects if you remove the mod.
