America’s latest hydrocarbon crush is shale gas. Shale gas has been around for a long time– the Marcellus Shale, which underlies much of Pennsylvania and western New York, dates back to the mid-Devonian period, almost four hundred million years ago– and geologists have been aware of its potential as a fuel source for many decades. But it wasn’t until recently that, owing to advances in drilling technology, extracting the gas became a lucrative proposition. The result has been what National Geographic has called “the great shale gas rush.” In the past ten months alone, some sixteen hundred new wells have been drilled in Pennsylvania; it is projected that the total number in the state could eventually grow to more than a hundred thousand. Nationally, shale-gas production has increased by a factor of twelve in the past ten years. Read more of this article on marcelus shale pennsylvania by clicking here
