The largest reserves are concentrated in China (32 trillion cubic meters), Argentina (23 trillion cubic meters), Algeria (20 trillion cubic meters), the U.S. (19-33 trillion cubic meters), Canada (16 trillion cubic meters), Mexico (15 trillion cubic meters), Australia (12 trillion cubic meters), South Africa (11 trillion cubic meters), Russian Federation (8 trillion cubic meters) and Brazil (7 trillion cubic meters). Together, these ten countries possess about 80% of the estimated world reserves of shale gas.
According to the Energy Information Administration, 3.6 trillion cubic meters (1.75% of estimated world reserves) are concentrated in Ukraine.
It is noted that the most promising shale gas extraction will be in those countries that are heavily dependent on natural gas imports, and have developed gas transportation infrastructure. These countries, along with Ukraine, include France, Poland, Turkey, Chile, South Africa and Morocco.
