Shale development – rock formations are horizontally drilled and fractured using water and other liquids under high pressure

June 7 (Bloomberg) — Poland said it’s far too early to estimate the potential size of its shale gas deposits or to know whether they can be accessed.

Poland has so far issued 58 licenses to companies including Chevron Corp. and Exxon Mobil Corp. to search for so-called unconventional gas, said Ewa Zalewska, director of the license department at the Environment Ministry.
Shale development, where rock formations are horizontally drilled and fractured using water and other liquids under high pressure, is driving a surge in U.S. natural-gas output. Its development in Europe could help the region diversify sources of energy and cut down on imports.
While consultants estimate Poland may have 1.4 billion to 3 billion cubic meters of shale gas, hard figures on volumes and accessibility won’t be known for two to five years, Zalewska said. Production will take 10 to 15 years, she said.
