This is a list of countries by net oil exports in barrels per day based on The World Factbook[1] and other sources.
[2] "Net export" refers to the export minus the import.
Note that the net export is approximate, since the import and export data are generally not for same year (though year-to-year changes are generally small).
Many countries are missing data for either imports or exports, but this generally indicates that the missing number is small.
