Using well data from the website FracFocus spanning 2008-13, the researchers found well depths ranged nationwide from deeper than 3 miles to as shallow as 100 feet.

The most recent such study, published in Environmental Science & Technology, finds that at least 6,900 oil and gas wells in the U.S. were fracked less than a mile (5,280 feet) from the surface ...

Shallow fracking raises questions for water, new Stanford research shows ... The states with the highest average water use per well were Arkansas, Louisiana, West Virginia and Pennsylvania.

Penneco Oil Co., on the other hand, has been fracking horizontal shallow wells for several years now. It perforates the casing at more than a dozen stages and pumps “off-the-shelf” frack fluid ...

Following up on the team’s earlier work [pdf] documenting methane contamination of drinking water in Pennsylvania, the authors analyzed 426 shallow water samples taken both recently and in the ...

That flow-back water is laced with fracking chemicals (which the industry does not have to disclose), as well as underground contaminants including naturally occurring radioactive materials that ...

He says well stimulation, which is one method of fracking, accounts for a tiny fraction of all of California's oil and gas production. The rest comes from traditional oil drilling and steam ...

An unusually shallow earthquake triggered by hydraulic fracturing in a Chinese shale gas field could change how experts view the risks of fracking for faults that lie very near the Earth's surface.

Five years ago, The Heartland Institute set out to correct some misperceptions about the hydraulic fracturing process (commonly known as “fracking”) that had gained traction in the opinions of ...

Fracking also uses very strong acids injected to dissolve formations as well. Water-injection is also common, to displace the oil and bring it up. Water is cheap, free.

Anti-fracking protesters outside a shale gas well site in Lancashire, UK. Fracking of oil and gas wells is a conundrum. On one hand, fracking was a key to releasing oil and gas from shale rock ...
