ABSTRACT

According to the US Energy Information Administration (EIA) Report (2013), 7,299 trillion cubic feet (Tcf) of shale gas technically recoverable resources (TRR) and 345 billion barrels (bbl) of shale oil TRR exist in the world. The EIA covered the most prospective shale formations in 41 countries that demonstrated some level of relatively near-term promise and that had a sufficient amount of geologic data for a resource assessment (Fig. 4.1).
