Inspired by a comment on my previous post, I decided to take a look at the data provided for crude oil consumption on the World Factbook. This include oil production, exports and imports. From this I calculated oil consumption to be simply oil produced plus oil imported minus oil exported. These numbers are given in bbl/day, which I believe is barrels per day.

There are only weak correlations between oil production or exports and GDP – while we consider oil producing countries to be rich, and indeed Qatar has the second-highest GDP per capita in the world, there are seemingly many other strong factors at play. Much stronger is the correlation between GDP and oil consumption:

Which unsurprisingly suggests those countries that consume a lot of oil are those who can afford it. Much more interesting, however, is to look at which countries export most of the oil that they produce and which keep it instead by plotting oil production against oil exports:

Those countries on the diagonal (y=x) line export all of the oil that they produce. The further a country is below the line, the more oil they keep rather than exporting. Curiously, there are some countries above the diagonal – exporting more oil than they produce! The Netherlands, for example produces 29,000 barrels per day but exports 850,000! This is possible because they import 1.8 million barrels per day, much of which apparently passes through on to other countries.
