FILE - In this file picture taken April 5, 2012, a rig of the Canadian-based Talisman Energy Inc. exploring for shale gas is pictured in the middle of muddy fields in the village of Szymkowo, in central Poland. Talisman is one among some two dozen international firms exploring shale gas deposits in Poland, but waiting with long-term strategy decisions for a law that would regulate gas production and distribution.Treasury Minister Mikolaj Budzanowski told The Associated Press, Friday, Jan. 11, 2013, that the law should be adopted in 2013 and take effect in 2015. Poland is hoping the fossil fuel will help develop mining and associated industries and will cut the nation's 70-percent dependence on expensive Russian imports. (AP Photo/Czarek Sokolowski, File)
