U.S. shale oil (and gas) production depends upon a frenzied level of drilling never before seen, according to a new paper out from Harvard. That’s because the wells accessed by new fracking techniques typically decline dramatically not long after being put into production.
The U.S. Environmental Protection Agency announced today that it has asked nine natural gas service companies to voluntarily give information about the chemical composition of fluids used in the hydraulic fracturing or “fracking” process.
Fracking fluids are known to contain dozens of chemicals, designed to make the fluids work better when drillers crack into gas deposits deep in the earth. But the exact composition of companies’ formulas was exempted in 2005 from the Clean Water Act, which requires companies to make public chemicals being introduced into the environment.
People who want to know more about how hydraulic fracturing in the natural gas industry might affect drinking water, can attend EPA meetings in July in Texas, Colorado, Pennsylvania and New York.
These states have witnessed increases in natural gas drilling, as oil and gas companies tap stores thousands of feet beneath the surface in areas such as the Marcellus Shale in New York and the Barnett Shale in Texas.
