Marcellus Shale Gas Drilling – Interactive Website

hydraulic-frac-graphic - Energy in Depth,

Did you know the following about Marcellus Shale and hydraulic fracturing …

  • A typical Marcellus Shale well is drilled 5,000 to 9,000 feet vertically and up to 10,000 feet horizontally
  • Each drill site requires between 3 and 5 million gallons of water per frack
  • There are more than 50 known chemicals that may be added to the water that is used for hydraulic fracturing
  • Approximately 10% to 30% of the total water used per frack returns to the surface with the extracted gas – the rest remains underground
  • The Marcellus Shale lies underneath about 90,000 square miles of Pennsylvania, New York and West Virginia and is believed to hold hundreds of trillions of cubic feet of natural gas.
  • Between January and June of 2011, Marcellus wells produced 432.5 billion cubic feet of natural gas

  1. Does anyone know the standards for treated plowback, production, or fraction water are to satisfy the state and the EPA? Are the standards published any where?

  2. Pickard Trepess says:

    3 million gallons of water is the amount used as drinking water in New York City about every 10 minutes. Much of that does not come back either !

  3. Alan J says:

    Robert that’s a good question. There must be someone who is in the water treatment world who could enlighten us. Or maybe the EPA will let us know…

  4. Brent Gunderson says:

    So that’s 300,000 to 1.5 million gallons that come up with each well….what the heck are they doing with all of that mess? Kind of a double-edged sword if you ask me. Sure PA needs the jobs and we certainly need the energy independence but if you destroy the environment in the process, it’s kind of a bad proposition overall.

  5. Jan says:

    Yes Brent the 300,000 to 1.5million gallons of used frac water can present a problem, or should I say a few problems thanks to the contamination and difficulties faced with treating the water and resultant brine. You don’t have to look too far around PA to see hundreds of abandoned mines and then take a look at the environmental disaster that’s happened to some of the rivers – now orange rivers. The EPA and DEP have put stops to the dumping of toxic waste but it’s a little too late for that.

    Now our hope is being able to use the latest technology to totally recycle and reuse the water AND brine in an environmentally friendly manner. It CAN now be achieved with the CLLEEN Water and Power treatment solutions and packages.
    So there is light at the end of the tunnel. We have to start somewhere to help save our environment whilst feeding our need for energy and water.

  6. Time is the scarcest resource and unless it is managed nothing else could be managed.
