Study Finds Large Emissions from Shale Gas Wells
“Researchers found higher-than-expected emissions of a potent greenhouse gas emanating from Pennsylvania wells, according to a study published Monday that adds to concerns about the environmental footprint of natural gas,” according to Fuel Fix .
“The study , conducted by Purdue and Cornell universities and published in the Proceedings of the National Academy of Sciences, is the latest to scrutinize methane emissions associated with natural gas development, with implications from New York to Texas.”
“Researchers used a specially equipped airplane to collect samples above the Marcellus Shale in southwestern Pennsylvania. They traced large methane emissions to seven wells that were were being drilled, a phase of operations not normally associated with such high levels. That suggests the U.S. Environmental Protection Agency’s estimates, released in an annual inventory, are not capturing all the released methane.”
