Sentences with phrase «shale natural gas extraction»

Not exact matches

But fracking opponents claim that, though natural gas is considered the greenest of fossil fuels, shale extraction is significantly more carbon - intensive than conventional production and may result in the release of large quantities of methane, itself a greenhouse gas.

Hydraulic fracturing, or «fracking,» is a petroleum - extraction procedure in which millions of gallons of water (as well as sand and chemicals) are injected deep into underground shale beds to crack the rock and release natural gas and oil.

However, the stark reality is that global emissions have accelerated (Fig. 1) and new efforts are underway to massively expand fossil fuel extraction [7]--[9] by drilling to increasing ocean depths and into the Arctic, squeezing oil from tar sands and tar shale, hydro - fracking to expand extraction of natural gas, developing exploitation of methane hydrates, and mining of coal via mountaintop removal and mechanized long - wall mining.

Fracking allows for the cheap extraction of natural gas from shale deposits that were previously inaccessible, and it is responsible for both the boom in natural gas production as well as the correlate controversy.
