Is that wanted or unwanted?
After all the geography of oil and rares has been known (and talked about) since before the EU3-->Vic conversion ... yet there were no murderous wars for Arabian, Texan or Caspian oil? Despite the weaknesses of the nations owning those provinces. Italy in particular never once saw invasion despite woefully inadequate land forces. Georgia was not raped tenfold and partitioned when Chinese and French forces laid her low. No price was paid by Italy and Georgia for the protection of the other powers...
Thinking about it, a nice way to put dynamics into the late game would be to have the size of the oil finds in various regions of the world be dynamic. Instead of knowing that Baku, Texas, Kuwait, Ploesti and so on are going to become big oil centers while Hannover, the Carpathians, the Kazan region, Pennsylvania and others will only be minor centers, maybe random events could determine which in fields the major oil finds of the 1920s and 1930s will be made? After all in real history people did not know either which oil fields would prove to be huge and which not. Pennsylvania saw a brief oil boom in the 19th century but that ended soon when the wells ran dry.
You should have KoM or someone else write random, non-deterministic Vic events set to trigger between, say, 1920 and 1936 which determine the final sizes of the oil provinces. Maybe also some follow up events for the 1936-1946 period in HoI where increased prospection efforts in the minor fields may or may not open up some more fields.
If you "seed" it so that 6-8 out of maybe ~30 provinces in HoI in different regions, which historically produced oil to some extent, may become the "big ones" like Baku or Kuwait or Texas, then it should become a bit more exciting. And not so annoyingly deterministic.
Write about 30 events, each one causing one successful exploration effort (flagging a field as "big strike") and two-three unsuccessful exploration efforts (flagging other fields as "disappointments") and sleeping some of the other events, each one set to a random frequency, and you could model this kind of process within the Victoria engine.
