Researchers trace water contamination to faulty gas wells

The contamination “stems from well-integrity problems such as poor casing and cementing,” Thomas H. Darrah, an earth science expert at Ohio State who led the study, said in a prepared statement.  More »

House tackling Keystone XL & gas exports in pre-election debate

Although gasoline prices have tumbled to four-year lows, that isn’t stopping lawmakers on Capitol Hill from exploiting concerns about high energy costs ahead of the mid-term elections.  More »

UTSA, Southwest Research find a new way to clean frack water

The University of Texas at San Antonio and the Southwest Research Institute say they have found an inexpensive way to treat the water that flows back to the surface after hydraulic fracturing. A team of researchers used a plant matter called biochar to remove impurities from the flowback water.  More »

Residents near gas wells twice as likely to report symptoms, study finds

Researchers found that residents living near Marcellus Shale natural gas wells were more likely to report rashes, sinus problems, coughs, sore throats, itchy eyes, nose bleeds and stuffy noses than those who lived farther away.  More »

Rigs in U.S. rose by 11 to 1,925, Baker Hughes says

The total energy rig count has almost doubled from five years ago as producers use horizontal drilling and hydraulic fracturing to draw record volumes of oil and gas out of shale formations from North Dakota to Texas.  More »

Water resources a problem for energy extraction worldwide, report finds

According to the analysis by the World Resources Institute, 38 percent of the earth’s shale gas and tight oil resources are in areas that are either arid or under high levels of water stress already _ a scenario that does not mesh with the high water demands of today’s extraction techniques.  More »

Researchers at work on using liquid nitrogen instead of water in fracturing

Petroleum engineers in Colorado are working on a process called cryogenic fracturing, which replaces water with searing cold liquid nitrogen or liquid carbon dioxide.  More »

Crude oil rides Texas’ rails with little tracking

For generations of producers drillers in Texas, where a vast pipeline system has grown with the fits and starts of the oil industry’s notorious business cycle, railroads provided little more than a relatively expensive last resort. But in the boom associated with the hydraulic fracturing, producers increasingly enlist trains to handle the glut.  More »

Study finds more arsenic in north Texas water wells near drilling

In the study, University of Texas at Arlington biochemists measured 100 wells across the Barnett Shale, believed to hold one of the largest natural gas reserves in the U.S., and compared the results to a similar study undertaken before hydraulic fracturing technology and higher natural gas prices opened the area to drilling.  More »

Feds advance hydraulic fracturing rule

The Obama administration is on track to impose new mandates governing hydraulic fracturing on public land by the end of the year, a move that threatens to topple the White House’s delicate balancing act assuaging worried environmentalists while still sustaining a domestic drilling boom that is bolstering the U.S. economy.  More »

Illinois state agency issues fracturing rules

he lengthy report follows months of delays and complaints over the process to draft rules governing hydraulic fracturing, or fracking, in Illinois. Industry officials say southern Illinois has rich deposits of natural gas, but a final draft of the rules — initially touted as a national model of both sides working together — has taken months for the agency to produce as industry groups warned the state was losing business.  More »

Feds to resume leasing for fracturing in California

The move will end a halt that has stood since a federal judge ruled in 2013 that the federal agency failed to follow environmental law in allowing fracking on public land in Monterey County.  More »
