Oil fields distribution

When analyzing the list of major producers of hydrocarbons in the world, the differences in the various countries are immediately highlighted. However it must be borne in mind that production is influenced by a vast series of factors, among which the potential of the reserves is only one of the main ones; technical factors can make  extraction more or less difficult even in the presence of large reserves and economic factors may lead to an increase in the production depending on the demand. For example, the production of the USA is very high compared to the estimated reserves, while in the Middle East, which has enormous reserves, the production/reserves ratio is very low. Therefore it is important not to confuse production with the size of the reserves. The largest producers are not necessarily the countries with the largest reserves. 49% of the oil reserves is localized in the Middle East. Most of the oil reserves are in Venezuela, accounting for 18.2%; the countries that follow are Saudi Arabia, Canada, Iran, Iraq, Kuwait, United Arab Emirates, Russia, United States and Libya. Most of the gas reserves, instead, are in Russia, accounting for 25.1% of the world reserves, followed by the Middle East, Iran and Qatar, which together account for 28.7% of the total.
