Introducing StateImpact’s New Marcellus Shale App

StateImpact's new app tracks Marcellus Shale wells

Who’s drilling where?

It’s the basic question everyone wants to know about Pennsylvania’s Marcellus Shale boom, and it’s something StateImpact’s new interactive app will help answer.

More than 1,600 shale gas wells are plotted in the app, which reflects the state’s most-updated data for 2011. Click on a well, and you’ll learn who owns it, how much gas it’s producing, and whether Department of Environmental Protection inspectors have cited it for violations. Problem-free wells are green on the map. If inspectors have cited a site for violations, it’s plotted as a orange dot — and the citation details are listed on the page.

Every single well has its own own page, so you can link to them or share them via Twitter and Facebook. If you think there’s more we need to know about the drilling site, there’s a space for you to share comments, stories or pictures.

The app helps answer broader questions, too. Trying to figure out who the biggest players are, or what areas are drilling hot spots? You can navigate to wells by county, municipality or operator to learn that information.

Our app is based on data from DEP’s website. The department updates production information twice a year, and refreshes violation reports about once a month. The next production update is scheduled for early next month. We’ll refresh the app as soon as the new data is public.

Some context on the app’s information: the production data covers DEP’s last reporting period, so the total you’ll see for each well is the amount of gas produced between January and June 2011. The app only tracks producing wells, so the thousands of additional wells DEP has issued permits for, but aren’t yet producing, do not appear on the site. Finally, a reminder that 1,608 wells doesn’t mean there are 1,608 large drilling rigs dotting Pennsylvania. Energy companies drill multiple wells on each site.

So click on the app, and after you do, let us know what you think by sending us an email. Also, be sure to check back throughout the week, as we publish reports based on the information in the app.

    I haven’t noticed this in my state of West Virginia.  How was this made?

    NPR needs to be defunded NOW. Let’s see…George Soros, ultra-progressive, ultra liberal, gives 1.8 million to NPR to start his pet project called “State Impact”. Now go to the NPR site, specifically the State Impact area. Look who else is currently funding it:

    Doris Duke Charitable Foundation
    Ethics & Excellence in Journalism Foundation
    The William and Flora Hewlett Foundation
    The Melville Charitable Trust
    Open Society Foundation
    The Wallace Foundation
    Ultra progressives all. Now, does any honest-thinking person actually believe that reporting born of this parentage will be fair and balanced? Anyone? If you doubt me just visit the sites of the 8 different states covered by State Impact and look at the issues focused on and the slanted coverage thereof.

    Here in PA the major focus is drilling the Marcellus shale. EVERY SINGLE STORY is a hit piece against the industry and are little more than op/ed columns. State Impact? Couldn’t “impact” be both good and bad? Then where are the stories about how drilling has benefited PA? Jobs, tax revenue, economic plusses, less reliance on foreign energy, among others. Surely these things should rate at least a story or two every now and then.

    But I’m sure Scott Detrow and Suzy Phillps would like to keep their jobs. And when your bosses are Soros and Ann Beeson, well you just better be sure to toe the line.

    So how about it Scott &Suzy? How about a little balance? Surely not every person in PA is against drilling. Maybe you could find a few and stick your mic in their faces, as repulsive as you find this to be. You see, if you really want your stories to have the “impact” that Soros/Beeson intended with their grant, here’s what to do: Practice some honest, objective journalism and print of few of those stories I mentioned. That way, your hit pieces will actually have more legitimacy by comparison. Get it? I’m not sure that Soros/Beeson will be pleased, but if they remove you from the project at least you’ll have the satisfaction that you actually performed what you got into the journalism business to do – tell the truth.

      I have to say this site has been one of the only places around to get objective information about drilling.  There are very few sources of information NOT funded by the industry.  In my oppinion, our industry funded governor and legislators are putting the health and welfare of the citizens of Pennsylvania at risk by allowing this toxic industry to freely pollute our air and water.    He is also intent on taking away basic rights of citizens to have a voice in whether or not they want fracking to happen in their communities.  As a mother, I feel a strong responsibility toward allowing my children to grow up in a healty environment.  As it stands Pennsylvania is on a path toward large scale pollution and environmental devastation. I am a supporter of NPR because I can get unbiased information that is not available from other media sources.  I would not be if they simply repeated the same rhetoric as everyone else.  I thank them for quality reporting.

      I suggest that Penguin5B should buy a home near a Marcellus well at the price it would have brought before we all learned of the Marcellus and live in it.  And drink the water from the home’s water well and have his whole family drink the water.  This may give him a different perspective on the development of the Marcellus shale.  I believe that very few people are totally against any development of the Marcellus shale, but many people think it should be managed to make its development safe for those of us who are here now and those who will come after us.  I would wager even money that Penguin5B benefits in some way from the Marcellus.

      Drop the ad hominem attacks and address the issue of lessening enviromental damage.

    @Penguin5b: Everyone I know is against the drilling, specifically the chemical fracking technique. I’m all for a free market, but the issues raised about water usage, possible groundwater pollution, and the release of methane into neighboring wells is all very important stuff.

    • ajm8127

      I agree. I live right at the western tip of Allegheny county. It seem that the concern over the fracing fluid migrating through thee bedrock is masking another threat. We need to look at the thousands of ponds that hold the fracing fluid on the surface. Not only can spills occur, but out gassing of the compounds in the fluid is a major concern to nearby ingredients.

      I think that natural gas can be a great energy source as we move away from coal and towards truly renewable non fossil fuel energy. The economic benefits are undeniable. The drilling need the managed responsibly, however, and we know that the free market is not that great at keeping the public’s interest in mind.

    This information has been available on for the past year.

    $ is greater than fresh water,or lifes. people will die you will see, it will take many before they might stop, they know it is going to kill. People flock to high dollar jobs there, you will die first, workers are exposed to  Uranium and other radioactive backflush, good luck, Nature will fight back!!
