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.

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.

Modeling changes in the observed harmonic frequencies indicates that the spectral characteristics of seismic data can provide important information about hydraulic fracture geometry and fluid pressure at depth, leading to important insights into subglacial hydrologic processes.

In work that offers insight into the magnitude of the hazards posed by earthquake faults in general, seismologists have developed a model to determine the size of an earthquake that could be triggered by the underground injection of fluids produced as a by - product of hydraulic fracturing.

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.
