The tricky part is that once it switches over from the waste dirt, you'd probably want it to revert to infinite for the actual Crude Oil / Nat. Gas / etc output. I'm not entirely sure how the game is differentiating it, if it converts the node on the ground into something else or what. I circumvented the issue temporarily by disabling this mod, letting the oil derrick dig out the waste dirt, and then turning the mod back on.
