Foam could offer greener option for petroleum drillers

Hydraulic fracturing, or fracking, provides critical energy for society, but also uses large amounts of fresh water while producing corresponding amounts of wastewater. Water-based foams, which use about 90 percent less water ...

When oil and water mix

Hydraulic fracturing of organic-rich shales has become a major industry. The commonly used term for this extraction of hydrocarbons—fracking—is especially intriguing. Not only does it convey the process of breaking apart ...

The potential impact of hydraulic fracturing on streams

Concerns over hydraulic fracturing, an oil and gas extraction method that injects millions of gallons of freshwater and chemicals into shale, have largely focused on potential impacts on water quality. But, as scientists ...
