USGS says seven small earthquakes shake central Oklahoma
The U.S. Geological Survey has recorded seven small earthquakes shaking central Oklahoma in a span of about 14 hours.
Another tiny miracle: Graphene oxide soaks up radioactive waste
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
Fracking risks to ground water assessed
Methane levels 17 times higher in water wells near hydrofracking sites
A study by Duke University researchers has found high levels of leaked methane in well water collected near shale-gas drilling and hydrofracking sites. The scientists collected and analyzed water samples from 68 private ...
Answers on link between injection wells and quakes
States where hydraulic fracturing is taking place are experiencing unprecedented earthquake activity.
Fracking leaks may make gas 'dirtier' than coal
(PhysOrg.com) -- Extracting natural gas from the Marcellus Shale could do more to aggravate global warming than mining coal, according to a Cornell study published in the May issue of Climatic Change Letters (105:5).
Nanotracer tester tells about wells
A tabletop device invented at Rice University can tell how efficiently a nanoparticle would travel through a well and may provide a wealth of information for oil and gas producers.
Energy industry develops nontoxic fracking fluids
The oil and gas industry is trying to ease environmental concerns by developing nontoxic fluids for the drilling process known as fracking, but it's not clear whether the new product will be widely embraced by drilling companies.
Study ties oil, gas production to Midwest quakes
Oil and gas production may explain a sharp increase in small earthquakes in the nation's midsection, a new study from the U.S. Geological Survey suggests.
Analysis of fracking wastewater yields some surprises
Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that the wastewater ...
US carbon emissions in surprise drop
US emissions of carbon dioxide blamed for climate change fell in 2011 and have slipped to a 20-year low this year as the the world's largest economy uses more natural gas and less coal, data shows.
No matter the drilling method, natural gas is a much-needed tool to battle global warming: study
No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.
Researchers challenge study on hydrofracking's gas footprint
(PhysOrg.com) -- A Cornell study's contention that hydraulic fracturing would be worse for climate change than burning coal is being challenged by another study, also by Cornell researchers.
Stray gases found in water wells near shale gas sites
Homeowners living within one kilometer of shale gas wells appear to be at higher risk of having their drinking water contaminated by stray gases, according to a new Duke University-led study.
