Ross and Mahdavi's dataset of oil and gas production contains information "about the volume and value of oil and natural gas production in all countries from 1932 to 2014." They note that "to calculate the total value of production, we multiply the volume by the world price for oil or gas. Since these are world prices for a single (benchmark) type of oil/gas, they only approximate the actual price, which varies by country according to the quality, the terms of contracts, the timing of the transactions, and other factors." The dataset also contains production data for some countries before they became sovereign. The original dataset is available at http://dx.doi.org/10.7910/DVN/ZTPW0Y
