Though the fluids were natural and not the byproduct of drilling or hydraulic fracturing, the finding further stokes the red - hot controversy over fracking in the Marcellus Shale, suggesting that drilling waste and chemicals could migrate in ways previously thought to be impossible.
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.
Previous studies have shown that fracking fluids contain high levels of salts, barium and radioactive elements, in addition to human - made chemicals added in the process of hydraulic fracturing.
But according to a panel of geologists at the AAAS Annual Meeting, the culprit isn't hydraulic fracturing, or «fracking,» in which geologists crack open subsurface rocks to extract oil and gas; instead, it's the processes associated with pumping wastewater and other fluids back into the ground.
Fracking — or hydraulic fracturing — is a process in which rocks are deliberately fractured to release oil or gas by injecting highly pressurised fluid into a borehole.
They looked both at wells used for enhanced oil recovery — in which fluid is injected to flush lingering oil from a depleted reservoir — and at those used to dispose of wastewater from conventional oil and gas extraction or from hydraulic fracturing (fracking).
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.
When hydraulic fracturing or «fracking» to access unconventional oil and gas reserves was a hot topic in the fossil fuel industry, Ryerson was tapped to lead a team to develop GEOS — a dynamic computational rock mechanics and hydrologic tool — that can model facture propagation, resulting seismic signals and pressure - driven fluid flow through a rock mass.
According to Gupta, who is part of the research team, StimuFrac consistently outperformed conventional fluids used for hydraulic fracturing and «is believed to have lower critical pore invasion pressure that provides further advantage over conventional fracking fluids.»
Another prime concern is water contamination either from poorly constructed wells or mismanagement of water and other fluids used during hydraulic fracturing, or fracking, of wells to liberate gas from the shale.
The shale energy surge also is spurring innovation: waterless hydraulic fracturing fluid, methods to decontaminate and recycle water used in fracking and more.

During hydraulic facturing, known as fracking, large volumes of fluid are pumped underground to pressurize and break rock, thereby releasing trapped natural gas.

The method combines a new form of horizontal drilling with hydraulic fracturing — more commonly known as fracking GThe process blasts open fissures in underground shale - rock formations by injecting a high pressure combination of fluids, chemicals and proppants causing the fossil fuel to flow to the production well.
