A new study by scientists from Purdue and Cornell suggests that the methane emissions from shale gas could be much higher than previously thought. The study, published in the Proceedings of the National Academy of Sciences, looked at fugitive methane emissions in Pennsylvania by flying an airplane over drilling sites and collecting samples. What they found was a bit unnerving. “It is particularly noteworthy that large emissions were measured for wells in the drilling phase — in some cases 100 to 1,000 times greater than the inventory estimates,” said Purdue chemistry professor Paul Shepson...............................................Full Article: Source
