  • xls

This graph illustrates the production of natural gas in thousands of billions of cubic meters (both conventional and unconventional).

Global production of natural gas has been rising constantly over the past 40 years. It tripled between 1970 and 2010. In 2010, the largest worldwide producers were the United States with 20% of global production (including unconventional natural gas), Russia (18%), Canada (5%) , Qatar (4%) and Iran (4%). Two thirds of global production takes place in 10 countries. It is important to note that while the Middle East represents close to 40% of proven global reserves, it only represents 16% of global production.
