ignored (help)Two alternatives to transport the proppant can be used, either a high viscosity fluid or a high flow rate. The first one generates large fractures while the second one causes small micro fractures in the formation.
In our work to oppose fracking, the Park Foundation has simply helped to fuel an army of courageous individuals and NGOs,' or non-governmental organizations, said Adelaide Park Gomer, foundation president and Park heir, in a speech late last year.
Beta emitters, including 3H and 14C, may be used when it is feasible to use sampling techniques to detect the presence of the radiotracer, or when changes in activity concentration can be used as indicators of the properties of interest in the system. Gamma emitters, such as 46Sc, 140La, 56Mn, 24Na, 124Sb, 192Ir, 99Tcm, 131I, 110Agm, 41Ar and 133Xe are used extensively because of the ease with which they can be identified and measured. ... In order to aid the detection of any spillage of solutions of the 'soft' beta emitters, they are sometimes spiked with a short half-life gamma emitter such as 82Br

The shale-drilling frenzy in the Permian has enabled the United States not only to reduce crude-oil imports, but even to become a major exporter [...] New technologies for drilling and hydraulic fracturing helped bring the break-even price
More than a quarter-century of efforts by some lawmakers and regulators to force the federal government to police the industry better have been thwarted, as E.P.A. studies have been repeatedly narrowed in scope and important findings have been removed
While environmentalists have aggressively lobbied the agency to broaden the scope of the study, industry has lobbied the agency to narrow this focus
The Times reviewed more than 30,000 pages of documents obtained through open records requests of state and federal agencies and by visiting various regional offices that oversee drilling in Pennsylvania. Some of the documents were leaked by state or federal officials.
Hydrofracturing a horizontal Marcellus well may use 4 to 8 million gallons of water, typically within about 1 week. However, based on experiences in other major U.S. shale gas fields, some Marcellus wells may need to be hydrofractured several times over their productive life (typically five to twenty years or more)

: CS1 maint: multiple names: authors list (link)During much of the fracking boom, the US economy grew and emissions declined. One study found that between 2005 and 2012, fracking created 725,000 jobs. That's largely due to natural gas from fracking displacing coal in electricity production.

... hydraulic fracturing techniques spurred a historic U.S. production boom during the decade that has driven down consumer prices, buoyed the national economy and reshaped geopolitics.
