It’s official — the U.S. government’s authoritative Energy Information Administration has confirmed that the world’s three leading shale gas producers are U.S., Canada, and China, respectively.
According to the “Technically Recoverable Shale Oil and Shale Gas Resources: An Assessment of 137 Shale Formations in 41 Countries Outside the United States” analysis prepared by Advanced Resources International for the EIA, in comparison with 2011 figures, 41 countries were assessed to have recoverable shale gas reserves, up from 32 two years ago. The number of basins with recoverable shale reserves increased from 41 in 2011 to 48 in 2013, and the number of formations containing shale gas nearly doubled in the same time period, from 69 in 2011 to 137 in 2013. Worldwide, estimates of “technically recoverable resources” of shale gas also increased from 6,622 trillion cubic feet in 2011 to 7,299 tcf two years later. Shale/”tight oil” estimates also rose, more than 1,000 percent, from 32 billion barrels in 2011 to an impressive 345 bb.
