天然氣之國

Gasland is a 2010 American documentary film written and directed by Josh Fox. It focuses on communities in the United States where natural gas drilling activity was a concern and, specifically, on hydraulic fracturing ("fracking"), a method of stimulating production in otherwise impermeable rock. The film was a key mobilizer for the anti-fracking movement, and "brought the term 'hydraulic fracturing' into the nation's living rooms" according to The New York Times. Fracking is a technique that has been used routinely since the late 1940s as an aid to stimulating production in oil and gas wells. Horizontal drilling, a recent innovation in drilling techniques, can create horizontal pathways deep within the Earth, and has successfully incorporated hydraulic fracturing to release fluids from shale formations.
