Ah, yes, I remember those WiF points. They were assigned for the effect, not in relation with the real production.
I have detailed data (I will post them tonight) but in short, America's share in world oil production exceeded 65%. That production was located in the United States, Venezuela and Mexico too.
The second region, far behind, started in the Caucasus and went south to the persian and iraqui oil fields.
The third, again far behind the second, was modern world Indonesia.
The rest, including Romania, Burma, etc, was negligible in comparison.

Fuel was rationed in the U.S. during the war, but the book I read claimed that the problem was not oil, which was plentiful. The idea behind it was to reduce rubber needs.

An additional idea - pipelines. The pipelines from the iraqui fields to the mediterranean were vital for the british war effort in the mediterranean (there were two, one to Haifa and other to French Lebanon), for example. And the U.S. built one big pipeline from the Gulf to the northen states were the industries were located (that pipeline was far more economical than a continuous stream of tankers, and in addition avoided the terrible losses that U-boats were inflicting on the allied merchant fleets in that area).
