# Circa 1940, what was the oil production of each nation?

I'm looking for a source that lists all crude oil production by each nation, as it was in 1940. The reason is to understand geopolitics of the time, especially the oil security (or lack thereof) of each nation participating in WW2.

So far I've only found the US at 4 million barrels per day according to this graph.

• league of nations yearbook would have a reasonable summary. – pugsville Nov 11 '16 at 10:43

• @pugsville Thanks, but I'm confused about pages 131 and 132. Page 132 is production of petrol products (like gasoline), which is different than crude oil. I don't know what page 131 is tabulating, maybe imports? – DrZ214 Nov 11 '16 at 11:05
• my math gives 3.4 million barrels a day for 1939. (remember 1939 not 1940 figure) close enough not to be concerned. – pugsville Nov 11 '16 at 11:54
• @pugsville Thanks, I was dividing by 7.33 instead of multiplying by 7.33. If you make this into an answer I'll accept it. – DrZ214 Nov 11 '16 at 12:41

Here is a link with annual oil production in metric tons (Mt), 1936-1948.

The US is by far and away the world's largest oil producer (over 180 million MT in 1940), followed by the Venezuela and the Soviet Union (30 and 27 million MT respectively). The next tier includes Indonesia and Iran (about 8 million MT each), trailed by Mexico and Romania (6 million MT each). Germany got most of her oil from Romania, and could certainly have used Soviet or Iranian oil. In Asia, the East Indies (modern Indonesia) was the big prize.

• On that page it says: "Source: BR Mitchell". What exactly is BR Mitchell? – DrZ214 Nov 12 '16 at 6:01
• @DrZ214: It is a compiler of international statistics. amazon.com/International-Historical-Statistics-B-R-Mitchell/dp/… – Tom Au Nov 12 '16 at 23:55
• BTW, about `Germany got most of her oil from Romania`, I found this on wikipedia: en.wikipedia.org/wiki/… : `In 1938, two thirds of German oil supply came from the United States and Latin America`, and it cites a book tho I don't have it. – DrZ214 Aug 3 '17 at 22:55
• @DrZ214: That was true in 1938, but of course it changed "afterward." Basically, Germany did have the advantage of having stockpiled U.S. oil before the war. – Tom Au Aug 3 '17 at 23:09
• Thanks, I opened a new question about it so we can get more info: history.stackexchange.com/questions/39365/… – DrZ214 Aug 4 '17 at 1:16

Thanks to user:pugsville for pointing out the League of Nations reports. I chose one with a 1940 column, even though some spaces were not filled in due to war. But as it turns out, all nations producing more than a million tons of oil have a 1940 number.
