Fracking for oil and gas uses millions of pounds of chemicals, some of which are toxic or carcinogenic. Two researchers summarize what companies have disclosed and call for more transparency.
New research shows that injecting wastewater deep underground can cause earthquakes far from the injection site. It also raises questions about which rock layers are the safest injection targets.
New research shows the size of man-made earthquakes is linked to how deep industry wastewater is injected into the ground.
South Africa has been considering shale gas development in the Karoo region. The gas, will be expensive to explore and extract, will be used as part of the country’s energy mix.
Shale gas holds considerable advantages. But there are still a number of uncertainties around whether South Africa is ready for such a bold step.
