As far as reduced OP mat distribution, maybe they could put in something so that the drill actually fails or wears out over time? That way you at least have to maintane the OP in some manner. The drill could actually randomly break, wear out over a given amount of time or even simply have to be removed and a new one purchased because there are no longer resources available at that area. We run out of sup mats when we dig so why would "OP materials" be any different?
