Study links hundreds of Ohio quakes to fracking

COLUMBUS, Ohio — A new study suggests fracking triggered hundreds of small, unnoticeable earthquakes in eastern Ohio late last year, months before the state first linked seismic activity to the much-debated oil-and-gas extraction technique. The report, which appears in the November issue of the journal Seismological Research Letters, identified nearly 400 tremors on a previously unmapped fault in Harrison County ...

Study shows how drilling wastewater causes quakes


WASHINGTON (AP) — A new study explains how just four wells forcing massive amounts of drilling wastewater into the ground are probably shaking up Oklahoma. Those wells seem to have triggered more than 100 small-to-medium earthquakes in the past five years, according to a study published Thursday by the journal Science. Many of the quakes were much farther away from ...

Fracking study finds new gas wells leak more

Seth Borenstein | The Associated Press WASHINGTON (AP) — In Pennsylvania’s gas drilling boom, newer and unconventional wells leak far more often than older and traditional ones, according to a study of state inspection reports for 41,000 wells. The results suggest that leaks of methane could be a problem for drilling across the nation, said study lead author Cornell University ...

Cornell study: defects responsible for gas well leaks


Shane Thielges | Shale Plays Media A study released today by Cornell University found that defects in Pennsylvania’s gas wells are responsible for methane leaks that contribute to global warming. According to Climate Central, the study examined environmental compliance records from over 40,000 wells constructed between 2000 and 2012. About 9.1% of those wells were found to have defects that ...
