  2. Environmental impact of fracking - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of_f...

    Hydraulic fracturing is a driver of climate change. [4] [29] However, whether natural gas produced by hydraulic fracturing causes higher well-to-burner emissions than gas produced from conventional wells is a matter of contention. Some studies have found that hydraulic fracturing has higher emissions due to methane released during completing ...

    Germany also had the largest hydraulic fracturing jobs in Europe, using up to 650 tonnes of proppant per well. Most German fracs used water- or oil-based gels. [34] The most popular target formation for hydraulic fracturing was the Rotliegend Sandstone. Hydraulically fractured wells are today the source of most of German natural gas production.

  4. Environmental impact of fracking in the United States

    en.wikipedia.org/wiki/Environmental_impact_of_f...

    Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.

  5. Fracking - Wikipedia

    en.wikipedia.org/wiki/Fracking

    Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...

    Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.

  7. Fracking and radionuclides - Wikipedia

    en.wikipedia.org/wiki/Fracking_and_radionuclides

    Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, particularly from unconventional reservoirs. [1]

  9. Induced seismicity - Wikipedia

    en.wikipedia.org/wiki/Induced_seismicity

    Hydraulic fracturing is a technique in which high-pressure fluid is injected into the low-permeable reservoir rocks in order to induce fractures to increase hydrocarbon production. [60] This process is generally associated with seismic events that are too small to be felt at the surface (with moment magnitudes ranging from −3 to 1), although ...
