Sentences with phrase «unconventional oil and gas extraction»

After over six years of campaigning against fracking by Friends of the Earth Scotland and local communities, the Scottish government announced on 3 October to effectively ban unconventional oil and gas extraction - in short: fracking — in the whole country.

Mining projects (37 %) and water impounded behind dams (23 %) are the most commonly reported causes of induced earthquakes, but unconventional oil and gas extraction projects using hydraulic fracturing, are now a frequent addition to the database, said Miles Wilson, a geophysicist at Durham University working on the HiQuake research effort.

That surge has coincided in time and place with the boom in unconventional oil and gas extraction such as hydraulic fracturing, or «fracking,» in which high - pressure fluid is injected into the ground to break up the underlying rock and release trapped gas or oil.

Not exact matches

Fluid injection can occur with conventional oil and gas extraction methods, which extract fuel from underground pools, and with unconventional methods like fracking, which recover oil and gas from small voids in rocks.

The alternative pathway, which the world seems to be on now, is continued extraction of all fossil fuels, including development of unconventional fossil fuels such as tar sands, tar shale, hydrofracking to extract oil and gas, and exploitation of methane hydrates.

Since the peak of crude oil production a decade ago, the fossil fuel industry has been forced to resort to costly and unconventional methods of extraction — arctic drilling and shale gas fracking among them — giving rise to unprecedented economic and environmental hazards.

Separate production models were developed for mining (coal and unconventional oil) and field (gas and conventional oil) operations, which reflected the basic differences in extraction and processing techniques.

By the time Mitchell and Devon Energy combined to «crack the Barnett» in 2002, work on unconventional gas extraction had been underway for decades, tracing back to the oil embargo and even before that to the nuclear tests of the 1960s.

The alternative pathway, which the world seems to be on now, is continued extraction of all fossil fuels, including development of unconventional fossil fuels such as tar sands, tar shale, hydrofracking to extract oil and gas, and exploitation of methane hydrates.

The extraction of unconventional gas and oil poses a significant threat to the climate, the environment and to local communities.

The ratio of energy returned on energy invested (EROEI) for fossil energy production has tended to fall as high - quality deposits of oil, coal, and natural gas are depleted, and as society relies more on unconventional oil and gas that require more energy for extraction, and on coal that is more deeply buried or that is of lower energy content.
