Sentences with phrase «trapped oil or gas»

Not exact matches

Hydraulic fracturing, or fracking, deploys a mix of water, sand and chemicals at high pressure to release gas or oil trapped in rocks.

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.

Hydraulic fracturing, or fracking, the rock - cracking method to release trapped oil and natural gas, always takes place thousands of meters below Earth's surface — or so many people assume.

And, although a few projects such as the Sleipner gas field in the North Sea or oil fields owned by the EnCana Corporation in Calgary, Alberta have proved that CO2 can be pumped underground and remain trapped below cap rock, they are aimed at enhancing recovery of the fossil fuels in those fields rather than permanently storing the greenhouse gas.

Hydraulic fracturing, or fracking, is a method of hydrocarbon recovery that uses high - pressure injections of fluid to break apart rock and release trapped oil and natural gas.

Various Updates In a move that environmental campaigners had sought for years (as had I), the Environmental Protection Agency has issued final rules that could substantially cut emissions of heat - trapping methane, smog - forming volatile organic compounds and toxic air pollutants such as benzene from new, rebuilt or modified oil and gas wells and other infrastructure and operations.

The game - changer is «unconventional fossil fuels,» much of it trapped in shale — rock that often contains oil or gas.

By driving cars, using electricity from coal - fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat - trapping gases into the atmosphere.

That's because far more energy is trapped in uranium atoms than in the chemical bonds within wood, coal, oil, or natural gas.

Also known as hydraulic fracturing, fracking refers to using pressurized water and chemicals to release oil or natural gas trapped in underground rock formations.

The sandy water fractures the shale, releasing the gas or oil trapped inside.

Ignoring the mountains of evidence showing that the burning of coal, oil and other fossil fuels is causing unnatural levels of heat trapping gas in our atmosphere seems insane at this point, and we know that those who do are likely driven by ideology, their bank account or an overly active conspiratorial mind.
