Where water goes after fracking is tied to earthquake risk
In addition to producing oil and gas, the energy industry produces a lot of water, about 10 barrels of water per barrel of oil...
How slick water and black shale in fracking combine to produce...
Radioactivity in fracking wastewater comes from the interaction between a chemical slurry and ancient shale during the hydraulic fracturing process, according to Dartmouth College...
Modeling the effects of wastewater injection
In work that offers insight into the magnitude of the hazards posed by earthquake faults in general, seismologists have developed a model to determine...
Small earthquakes at fracking sites may be early indicators of bigger...
Stanford geoscientists have devised a way of detecting thousands of faint, previously missed earthquakes triggered by hydraulic fracturing, or "fracking."
The technique can be used...
Anticipating hazards from fracking-induced earthquakes in Canada and US
As hydraulic fracturing operations expand in Canada and in some parts of the United States, researchers at the 2017 Seismological Society of America's (SSA)...
Study reveals two seismic processes by which hydraulic fracturing induces tremors
In some parts of western Canada, small-to-moderate earthquakes have been induced by oil and gas hydraulic fracturing operations. In Alberta, this type of induced...
Study links groundwater changes to fracking
A new study has found heightened concentrations of some common substances in drinking water near sites where hydraulic fracturing has taken place. The substances...
