Eventually, Durham hopes that researchers will help to develop novel chemicals that could be used to make the entire hydraulic - fracturing process cleaner and more efficient.

«The operation of an enhanced geothermal system uses the injection of a fluid (water or carbon dioxide) to extract thermal energy from the rock located a few thousand metres below the surface, and whose permeability has been improved or stimulated previously with fracturing processes,» explains César Chamorro, one of the authors.

Understanding of fundamental processes and prediction of optimal parameters during the horizontal drilling and hydraulic fracturing process results in economically effective improvement of oil and...

He noted that the hydraulic fracturing process lends itself to more leakage because it takes more time to drill the well, requires more venting and produces more flowback waste, he said.

Understanding calving might turn out to be as difficult as understanding earthquakes: a quasi-analogous fracture process that is a notoriously difficult problem.

Continental's success for the second consecutive quarter over Whiting highlights the importance of improving hydraulic fracturing processes, including the use of larger amounts of sand, which the Oklahoma City - based company has helped pioneer.

As the article notes, the biggest risk is in chemical transport, and chemicals used in the hydraulic fracturing process are a miniscule proportion of those transported and in use in Australia every day.

But the contaminants can come from several sources: from the hydraulic fracturing process itself, from the waste water, from the pits where drilling chemicals are stored, or from transporting chemicals and wastewater.

The fact is they have potential but they are not light crude they have to be pressed out of the earth through a fracturing process that up until the price of oil went over 75 $ a barrel was deemed too expensive by the oil companies to go after.

The downsides are a fractured process and responsibility that requires careful planning, contractual agreement, management and expertise at both ends of the operation.»

(Industry groups have seized on some recent findings that leaky wells, and not the fracturing process itself, might be responsible for tainted ground water in certain places.)

That's in part because the identity of the chemicals used by the gas industry for drilling and fracturing are protected as trade secrets, and because the EPA, based on an exemption passed under the 2005 Energy Policy Act, does not have authority to investigate the fracturing process under the Safe Drinking Water Act.

America's midsection has experienced an uptick in quakes due to part of the hydraulic fracturing process: Wastewater from the fossil fuel extraction is pumped deep into the ground, causing faults to separate and slip.

The panel's recommendations included public disclosure of chemicals during the hydraulic fracturing process, which is widely called «fracking.»

When faced with uncertainties about the chemicals used in the hydraulic fracturing process, the researchers deliberately overestimated the amount of toxic chemicals that would reach the environment to ensure they weren't minimizing fracking's health impacts, Miller said.

Much of the uncertainty relates to the hydraulic fracturing process.

USGS's studies suggest that the actual hydraulic fracturing process is only very rarely the direct cause of felt earthquakes.

The study, to be published in Water Resources Research on October 20, demonstrates that fractures in surrounding rock produced by the hydraulic fracturing process are able to connect to preexisting, abandoned oil and gas wells, common in fracking areas, which can provide a pathway to the surface for methane.

Hydraulic fracturing processes, similar to those used in oil and gas production, also have been used in enhanced geothermal systems, but those processes have drawbacks due to the amount of water required, the potential toxicity of the chemicals used and the high costs of retrieving and treating the water.

The high - volume hydraulic fracturing process.

However, other mechanisms such as fluid withdrawal, enhanced oil recovery, or hydraulic fracturing processes can also result in induced earthquakes.»

The hydraulic fracturing process — pushing gallons upon gallons of chemical - laden water into shale rock in order to bubble up natural gas — takes place deep in the ground, thousands of feet below the earth's surface and thousands of feet below the shallow aquifers that provide drinking water.

This layering is part of the fracturing process, the breaking up or «exploding» of a recognisable image, a response, says Stubbs, to the ever expanding proliferation of broadcast and internet - based images that fill our world.

There's a substantial push toward recycling and cleaning water used or produced during the fracturing process.

This technology holds great potential to lower the «dread to risk ratio» surrounding the hydraulic fracturing process, in which water with traces of other substances is injected into a well at high pressure to fracture deep shale layers holding the gas.

Overall, the report demonstrates that industry practices, industry trends, and regulatory programs protect water resources at every step of the hydraulic fracturing process.

Through my research for the story map, I learned about the hydraulic fracturing process.

Gas companies that use the hydraulic fracturing process - a drilling technique that uses millions of gallons of water, combined with a fair amount of chemicals, to crack shale formations and extract natural gas - are exempt from the Safe Drinking Water Act, unless they use diesel as part of the frack fluid.

As is often the case with resource development, shale gas production also has raised local environmental concerns, largely centering on the amount of water used in the fracturing process and the need to handle, recycle, and treat fracturing fluids in a manner that addresses the risk of spills that can potentially affect water quality.

Another twist in the Marcellus Shale natural gas fracking saga: Scientists from SUNY Buffalo have found that the hydraulic fracturing process can release uranium naturally occurring in the shale and that it may pollute
