According to a recent report by the U.S. Energy Information Administration (EIA) there is an estimated 5,760 trillion cubic feet of technically recoverable gas located in shale rock formations within 32 countries around the world.
China has the largest reserves of countries examined in the study. It is estimated that China holds 1,275 Tcf. in shale based natural gas reserves.
China is gaining experience in shale gas production through operations in the United States. The Chinese National Offshore Oil Corporation (CNOOC) has recently acquired U.S. shale gas reserves. CNOOC has purchased interest in the shale gas operations in Colorado, Wyoming, and the Eagle Ford shale in Texas from Chesapeake Energy.
In addition to China, the report concludes the existence of large shale gas reserves in Argentina, Mexico, South Africa, France, Poland, and Canada.
The report did not include Russia and countries within Central Asia, the Middle East, Southeast Asia and Central Africa.
