ABSTRACT
Poland is characterized by presence of numerous sedimentary basins and petroleum provinces. Polish Outer Carpathians remains one of the first oil producing province in the World. Its Miocene flexural fordeep basin, one of the main gas province in Poland, contains biogenic methane at the shallow depths. In the western Poland the Rotliegend basin is producing gas since 50’ties. This is mainly dry gas, nitrogen and helium rich. Currently new exploration results allows to upscale the Rotliegend basin due to previously unrecognized tight gas opportunities. Up section in the same basin the Main Dolomite (formation within the Zechstein evaporates) is a reservoir for both oil, condensate and gas, commonly sour and overpressured. In the offshore Baltic Basin oil and condensate is produced from the Middle Cambrian sandstone. Moreover a few very small oil and gas fields were discovered so far in the Devonian-Carboniferous Lublin and Pomerania basins. Recently unconventional potential of Poland gets higher attention. Significant resources of a coalbed methane are documented particularly for the Upper Silesian Coal Basin (100-160 Bcm of recoverable gas). The Lower Paleozoic shale in the Baltic-Podlasie-Lublin Basin is being still evaluated, though at current understanding its shale gas recoverable prospective resources are within a range of a few to several Bcm.
