In the conservative scenario resources are estimated at 346-768 billion cubic metres - enough to supply the country for 35-65 years. The higher estimates indicate that Poland's total reserves could reach 1.9 trillion cubic metres. A study in May 2012, conducted by Saponis Investments S.P., has shown a potential 376 billion cubic metres of shale gas under just three concessions in northern Poland, indicating that reserves may be more abundant than allowed for by the Polish Geological Institute.According to initial estimates from the US Energy Information Administration, not yet confirmed by exploratory drilling, Poland’s shale gas reserves are among the largest in Europe, with a potential 4.1 trillion cubic metres (148 trillion cubic feet) of technically recoverable resources, although the scale of these reserves is still being determined.
