This is a list of countries by oil production , as compiled from the . Energy Information Administration database for calendar year 2016, tabulating all countries on a comparable best-estimate basis. Compared with shorter-term data, the full-year figures are less prone to distortion from periodic maintenance shutdowns and other seasonal cycles. The volumes in the table represent crude oil and lease condensate , the hydrocarbon liquids collected at or near the wellhead. The volumes in the table do not include biofuel . They also do not include the increase in liquid volumes during oil refining ("refinery gain"), or liquids separated from natural gas in gas processing plants ( natural gas liquids ). 
The United States took caution on the amount of production created during World War II because of them still recovering from the Great Depression. However FDR set enormous production goals to fulfill during the war. The early 1940's were set to have 60,000 aircraft increasing to 125,000 in 1943, also with the production of 120,000 tanks and 55,000 aircraft in the same time period. Ford Motor Company in Michigan built one Ford car made of 15,000 parts on the assembly lines every 63 seconds. Fords production contributed to America's total production of vehicles in 1941 totaling three million. America surpassed production numbers that caused employment to skyrocket. Compared to Japan,, America excelled production at the rate it took Japan all war, building more planes in 1944 than Japan built in the years 1939-1945. As a result, half of the production of war from the whole world came from America. Government paid for production using techniques of selling war bonds to finical institutions, rationing household items, and creating more tax revenues. Contributing to the manufacturing boom during the war can trace back to the 1930's and the help of the Alcoa plant. The Alcoa plant prepared millions of pound of aluminum that was used for the production of 304,000 airplanes created during the war. The United States quickly adjusted to huge amount of production loads that can be credited for the hundreds of thousands military and war products used during World War II.
