with poll: Natural gas drilling technique called 'hydrofracking' comes to Michigan: 7 facts you should know
Water-intensive drilling techniques used for the first time in Michigan in the last year extract natural gas from deeper underground than ever before.
The new tactics could result in more natural gas used for generating electricity, heating homes and cooking. But water-intensive drilling tactics worry Ann Arbor environmentalists, said Marc Smith, a senior policy manager for the National Wildlife Federation’s Great Lakes Regional Center in Ann Arbor.
Companies have drilled two exploratory wells in the northwest Lower Peninsula’s Collingwood and Utica Shale within the last year that use high pressure "fracking" or hydrofracking to get at natural gas.
The depth, combined with the use of horizontal drilling, requires the injection of millions of gallons of water, plus a mix of sand and chemicals, to get to the gas-bearing shale in deeper, hard-to-reach spots underground.
Groups like the NWF are concerned about the environmental implications of the millions of gallons of water needed for hydrofracking; the possibility of predatory lease arrangements between private land owners and gas companies; and the environmental impact of secret chemicals used to help break up the gas-bearing shale.
The Ann Arbor office, along with other groups, is starting to push for more regulatory controls, Smith said.
