SUMMARY Poland has some of Europe's most favorable infrastructure and public support for shale development. The Baltic Basin in northern Poland remains the most prospective region with a relatively simple structural setting. The Podlasie and Lublin basins also have potential but are structurally complex, with closely spaced faults which may limit horizontal shale drilling. A fourth area, the Fore-Sudetic Monocline in southwest Poland, is less recognized but has non-marine coaly shale potential similar to Australia's Cooper Basin. Poland's risked, technically recoverable shale resources are estimated at 146 Tcf of shale gas and 1.8 billion barrels of shale oil in four assessed basins, Tables VIII-1 and VIII-2. Lithuania adds 0.4 Tcf and 0.3 billion barrels of risked, technically recoverable shale gas and shale oil resources, Table VIII-3. Kaliningrad adds 2.0 Tcf and 1.2 billion barrels of risked, technically recoverable shale gas and shale oil resources, Table VIII-3. Initial exploration has confirmed the shale resource potential but suggests that reservoir conditions are more challenging than originally anticipated by industry. New data collected since our 2011 resource assessment resulted in a 20% reduction in EIA/ARI's estimate of Poland's shale resources, on an energy-equivalent basis.
