Drilling & Fracturing
Energy Institute at the University of Texas at Austin Study Reviewing Groundwater Contamination Claims Finds Fracturing Not At Fault
(information reported from an Energy Institute press release)
"Hydraulic fracturing of shale formations to extract natural gas has no direct connection to reports of groundwater contamination, based on evidence reviewed in a study released Thursday by the Energy Institute at The University of Texas at Austin.
The study, released at the annual meeting of the American Association for the Advancement of Science (AAAS) in Vancouver, British Columbia, foundthat many problems ascribed to hydraulic fracturing are related to processescommon to all oil and gas drilling operations, such as casing failures or poor cement jobs.
University researchers also concluded that many reports of contamination can be traced to above-ground spills or other mishandling of wastewater produced from shale gas drilling, rather than from hydraulic fracturing per se, said Charles "Chip" Groat, an Energy Institute associate director who led the project."
