02.03.2012 16:35Poland Decreases Quantities of Expected Shale Gas Reserves
The country, seeking to reduce its reliance on Russian gas, may hold 5.2 trillion cubic meters of gas, or enough fuel trapped in shale to meet its needs for 300 years, the U.S. Department of Energy said

Poland’s estimated shale gas reserves, believed to be the largest in Europe, may be cut once data is analyzed from the country’s first wells, the Polish Geological Institute said.
“Core logs from Polish wells are being analyzed with the help of U.S. technology,” Miroslaw Rutkowski, a spokesman for the institute, said for Bloomberg. “As result, we’re expecting that our estimates will be lower than those of the EIA,” he said, in a reference to the Energy Information Administration.
Drilling horizontal wells and using so-called hydraulic fracturing to open fissures in shale rock has made the U.S. the world’s largest gas producer. While Poland was identified as the European country with the best shale-gas potential, initial results from drillers including Exxon Mobil Corp. and 3Legs Resources Plc have disappointed.
The country, seeking to reduce its reliance on Russian gas, may hold 5.2 trillion cubic meters of gas, or enough fuel trapped in shale to meet its needs for 300 years, the U.S. Department of Energy said in April. The estimate was made by applying recovery rates from shale areas producing in the U.S.
The Polish institute and the U.S. Geological Survey are working to analyze drilling results and will publish an estimate of technically recoverable resources of shale gas in Poland on March 21. The revised estimate won’t be definitive as only about a dozen exploration wells have been drilled in Poland so far, Rutkowski said.
