The fracking drilling technique used to tap shale oil and gas is unlikely to trigger earthquakes, but underground injection of waste water from drilling offers more risks for seismic activity, a new U.S. study said on Friday.
Advances in hydraulic fracturing, or fracking, have dramatically increased U.S. oil and gas production from shale formations.
Companies have been moving into the area for the past two years, leasing or buying mineral rights and lining up areas for large drilling horizontal wells.
The drilling is projected to continue for up to 20 years, with thousands of new wells anticipated. While workers from out-of-state companies are drilling the wells now, it’s expected that Texans will be filling the jobs in the future.
