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...

Injection wells can induce earthquakes miles away from the well

A study of earthquakes induced by injecting fluids deep underground has revealed surprising patterns, suggesting that current recommendations for hydraulic fracturing, wastewater disposal, and...

Human-made earthquake risk reduced if fracking is 895m from faults

The risk of human-made earthquakes due to fracking is greatly reduced if high-pressure fluid injection used to crack underground rocks is 895m away from...

Oklahoma’s earthquakes strongly linked to wastewater injection depth

Human-made earthquakes in Oklahoma, USA, are strongly linked to the depth at which wastewater from the oil and gas industry are injected into the...

Fox Creek earthquakes linked to completion volume and location of hydraulic...

The volume of hydraulic fracturing fluid and the location of well pads control the frequency and occurrence of measurable earthquakes, new Alberta Geological Survey...

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...

Hydraulic fracturing rarely linked to felt seismic tremors

New research suggests hydraulic fracturing and saltwater disposal has limited impact on seismic events. For the past two years, UAlberta geophysicist Mirko Van der Baan...

West Virginia groundwater not affected by fracking, but surface water is

Fracking has not contaminated groundwater in northwestern West Virginia, but accidental spills of fracking wastewater may pose a threat to surface water in the...

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...

Research finds way to make fracking safer

Study finds that wastewater injections cause man-made earthquakes, but the risk can be reduced through monitoring Injecting wastewater deep underground as a byproduct of oil...

Hydraulic fracturing chemical spills on agricultural land need scrutiny

Hydraulic fracturing, a widely used method for extracting oil and gas from otherwise impenetrable shale and rock formations, involves not only underground injections composed...

Hydraulic fracturing

What is Hydraulic Fracturing? Oil and natural gas, which are hydrocarbons, reside in the pore spaces between grains of rock (called reservoir rock) in the...

Some gas produced by hydraulic fracturing comes from surprise source

San Francisco--Some of the natural gas harvested by hydraulic fracturing operations may be of biological origin--made by microorganisms inadvertently injected into shale by oil...
