The analysis is based on data from thousands of fracking operations in the USA and natural rock fractures in Europe and Africa.” Quoted from the Durham University press release.More at Durham University.
An article on the Bloomberg.com website explains how some states are responding to the correlation between wastewater injection and shallow earthquake activity. Injection well disposal of hydraulic fracturing wastewater is declining rapidly as natural…More at Bloomberg.com.
While the ownership of oil and natural gas beneath a property has been rather well defined there are still significant uncertainties about who owns the ground water.More at Statesman.com.
“Hydraulic fracturing of shale formations to extract natural gas has no direct connection to reports of groundwater contamination [...] many problems ascribed to hydraulic fracturing are related to processes common to all oil and gas drilling operations, such as casing failures or poor cement jobs.” Quoted from the University of Texas at Austin press release.More at University of Texas at Austin.
The National Ground Water Association has published a position paper titled: “Hydraulic Fracturing: Meeting the Nation’s Energy Needs While Protecting Groundwater Resources.”More at National Ground Water Association.
A new regulation will require drillers in Texas to report the chemicals in their hydraulic fracturing fluid and the amount of water used to frack each well.More at The Texas Tribune.
The Ohio Department of Natural Resources has temporarily shut down a waste injection well that is suspected to have triggered earthquakes. The state has nearly 200 other injection wells that have not been associated with seismic activity.More at The Columbus Dispatch.
An article on the Platts.com website explains how Lawrence Livermore National Laboratory is studying how explosive detonations can be used as an alternative hydraulic fracturing in the production of natural gas from shale.More at Platts.com.
When a development project destroys an acre of wetlands the responsible company is often required to create another acre of new wetlands in the same watershed. This has fueled a new business of “mitigation banks”.More at Business Week.
It is never politically popular to accept out-of-state waste and injection well owners in Ohio are taking heat because they are injecting Marcellus Shale drilling waste from Pennsylvania. An article in the Houston Chronicle explains why so much Pennsyl…More at Houston Chronicle.
Many oil and gas companies that use hydraulic fracturing methods recycle the waste water produced during drilling. As a moratorium on hydraulic fracturing in New York is lifted the Niagara Falls Water Board is ready to accept hydraulic fracturing wast…More at WGRZ.

In Louisiana, a pipeline carries treated waste water from a paper mill to a natural gas field in the Haynesville Shale. The water is being recycled for hydraulic fracturing instead of being discharged into the Red River.More at UpstreamOnline.com.
The Shale Gas Advisory Board called for “making information about shale gas production operations more accessible to the public; taking immediate and long-term actions to reduce the environmental and safety risks of shale gas operations, with a particular focus on protecting air and water quality; creating a Shale Gas Industry Operation organization committed to improving operating practices; and continuing research and development to improve safety and environmental performance.”

Representatives of industry and government agencies often state that there has not been one documented case of hydraulic fracturing contaminating a private water supply well. However, an EPA report from 1987 links hydraulic fracturing with a contaminated water supply in Jackson County, West Virginia. Those opposed to hydraulic fracturing hope to get a lot of mileage out of that report. More in the New York Times.
The topic was also on the agenda at Chevron’s annual shareholder meeting.
An article on Platts.com reports on shareholder resolutions at ExxonMobil, Chevron and Ultra Petroleum calling for those companies to disclose information about the environmental and financial risks of hydraulic fracturing in the production of natural gas.
An article on the ShreveportTimes.com website considers the industry activity and environmental impact associated with the injection of salt water waste produced by drilling for natural gas in the Haynesville Shale.
“The Department of Energy’s Office of Fossil Energy (FE) announced favorable results from a demonstration project turning wastewater from drilling sites into clean water.” Quoted from the Energy Information Administration’s Natural Gas Update.
The FracFocus website is all about hydraulic fracturing. It contains information about the process, the chemicals that are used and contact agencies in states were oil and gas drilling is active. It also has a “Find A Well” feature that allows you to look-up wells and view the chemicals used in the hydraulic fracturing process. The site is provided by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission.
Mark Northam, director of the School of Energy Resources at the University of Wyoming says that horizontal drilling and hydraulic fracturing allow drillers to “manufacture a reservoir” in the Niobrara Shale. More in the Billings Gazette.

The impact of hydraulic fracturing on ground water supplies is a concern in almost every area where the well stimulation method is employed. The Texas Water Development Board has published an informative study: Northern Trinity/Woodbine GAM Assessment of Groundwater Use in the Northern Trinity Aquifer Due To Urban Growth and Barnett Shale Development. Get the report here.
The Railroad Commission has jurisdiction of natural gas drilling in Texas and the commission disagrees with the United States Environmental Protection Agency on the cause of domestic water well contamination in North Texas. EPA claims that Barnett Shale drilling has caused the problem. More in the Washington Post.
“As natural gas production has increased, so have concerns about the potential environmental and human health impacts of hydraulic fracturing in the United States. [...] The overall purpose of this study is to understand the relationship between hydraulic fracturing and drinking water resources. More specifically, the study is designed to examine the conditions that may be associated with the potential contamination of drinking water resources, and to identify the factors that may lead to human exposure and risks.” Quoted from the EPA publication announcement.
