How fluids flow through shale

Most of the world's oil and natural gas reserves may be locked up inside the tiny pores comprising shale rock. But current drilling and fracturing methods can't extract this fuel very well, recovering only an estimated 5 ...

How much water does US fracking really use?

Energy companies used nearly 250 billion gallons of water to extract unconventional shale gas and oil from hydraulically fractured wells in the United States between 2005 and 2014, a new Duke University study finds.

New contaminants found in oil and gas wastewater

Duke University scientists have discovered high levels of two potentially hazardous contaminants, ammonium and iodide, in wastewater being discharged or spilled into streams and rivers from oil and gas operations in Pennsylvania ...

Can we accurately model fluid flow in shale?

(Phys.org)—Given that over 20 trillion cubic meters of natural gas, a third of the United States' total reserves, are thought to be trapped in shale, and given the rush to exploit shale oil and gas resources by Australia, ...

Fracking shifts global energy balance

North America's shale oil and gas boom has shifted the balance in global energy markets, giving the US and Canada new leverage as exporters, despite the Middle East retaining a pivotal role.

NREL catalyst brings drop-in fuels closer

We live in a petroleum-based society, and the oil we use comes from plants that were buried eons ago and changed under pressure and high temperatures. As countries across the globe face dwindling oil supplies and the environmental ...

Research could be path to new energy sources

(PhysOrg.com) -- A team of researchers led by University of Kentucky College of Agriculture Professor Joe Chappell is making a connection from prehistoric times to the present that could result in being able to genetically ...
