Brine water that flows back from gas wells in the Marcellus Shale region after hydraulic fracturing is many times more salty than seawater, with high contents of various elements, including radium and barium. The chemistry ...
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.
(Phys.org)—Researchers have made a genetic analysis of the microbes living deep inside a deposit of Marcellus Shale at a hydraulic fracturing, or "fracking," site, and uncovered some surprises.
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.
Most earthquakes in the Barnett Shale region of north Texas occur within a few miles of one or more injection wells used to dispose of wastes associated with petroleum production such as hydraulic fracturing fluids, according ...
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.
A Duke University study of well water in northeastern Pennsylvania suggests that naturally occurring pathways could have allowed salts and gases from the Marcellus shale formation deep underground to migrate up into shallow ...
Certain oil and gas operations that involve injecting wastewater underground can cause earthquakes, but the risk from hydraulic fracturing is generally low, said a US scientific report Friday.
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.
(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.
