Very troubling. The sad thing is how much waste of natural resources still occurs. As you noted in another article we are also busy fouling and wasting water with this process.

The key to the ...Your article is very informative. The key to the problems of contamination, as you point out, is well bore integrity. There are many ways to "design" the well to protect the shallower water sands. Additional casing strings are normally added to protect shallow and intermediate water producing formations. Proper cementing techniques and close supervision of the cement job is essential (this is a key point). Cement bond surveys can be taken to determine if the casing is properly cemented prior to the fracture treatment. No human endeavor is 100% certain, but a good wellbore design and proper supervision can reasonably eliminate contamination. <br /><br />The current paranoia about fracking is based mostly on fear, fiction, distrust of oil companies, and in many cases motivated by groups with their own monetary agendas. Until viable energy sources are developed we are dependent on hydrocarbons. We can't just say no more development of hydrocarbon resources.<br /><br />Retired Petroleum Engineer<br />Ken, Ellen, Toby and Rileyhttps://www.blogger.com/profile/14884080565367570614noreply@blogger.comtag:blogger.com,1999:blog-6399730406480392183.post-39400624774997347862013-10-19T12:09:03.957-03:002013-10-19T12:09:03.957-03:00Not that I've found thus far.

In truth, the real transition that is happening is from fossil fuels to green technologies. Most of the new power installations are using green technologies. Our government needs to come up with a master plan on our energy sources and use. We cannot let the fossil fuel companies determine this plan, because they will surely act in their own interest. Unfortunately, they are currently the big gorilla in the room, and they are succeeding in deciding for all of us our energy policies.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6399730406480392183.post-77895774625872302572013-09-15T20:37:19.182-03:002013-09-15T20:37:19.182-03:00Bruce

As much concern as many of us have the political and economic desire to rip into these resources as a easy way to mask other problems is very real. I have heard how this can effect ground water but any idea as to what these up to now contained gases will do to the atmosphere?<br /><br />http://brucewilds.blogspot.com/2012/05/another-earth-needed.htmlBruce Wildshttps://www.blogger.com/profile/10181323607060607040noreply@blogger.com
