Concerns over possible link between injection wells and quakes

FORT WORTH, Texas (AP) — States where hydraulic fracturing is taking place have seen a surge in earthquake activity, raising suspicions that the unconventional drilling method could be to blame, especially the wells where the industry disposes of its wastewater.

Fracking generates vast amounts of wastewater, far more than traditional drilling methods. The water is pumped into injection wells, which send the waste thousands of feet underground. No one knows for certain exactly what happens to the liquids after that. Scientists wonder whether they could trigger quakes by increasing underground pressures and lubricating faults.

USGS: 7 small earthquakes shake central Oklahoma

GUTHRIE, Oklahoma (AP) — The U.S. Geological Survey has recorded seven small earthquakes shaking central Oklahoma in a span of about 14 hours.

The temblors are part of an increase in earthquakes across Oklahoma, Texas and Kansas that some scientists say could be connected to the oil and gas drilling method known as hydraulic fracturing, and especially the wells in which the industry disposes of its wastewater.

Halliburton forms energy joint venture in China

NEW YORK (AP) — Halliburton said Friday it is entering its first joint venture in China that will use hydraulic fracturing, or fracking, to unleash energy.

The Houston company, which provides drilling services to oil and gas operators, said it will create the joint venture with an affiliate of SPT Energy Group. The venture will focus on hydraulic fracturing and production enhancement services in Xinjiang, China.

Oklahoma has experienced twice the number of earthquakes this year as California, and some communities and environmental groups are concerned that the state's surge in hydraulic fracturing may be playing a role, Bloomberg reports.

EU energy chief urges Germany to keep open mind on fracking

Saying Europe could reap one tenth of its energy needs from hydraulic fracturing in shale, European Union Energy Commissioner Guenther Oettinger urged Germany to keep an open mind on fracking in light of recent recommendations that raise concern on the safety of the process, Reuters reports.

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 the wells than expected.

Combined, those wells daily pour more than 5 million gallons (19 million liters) of water a mile or two underground into rock formations, the study found. That buildup of fluid creates more pressure that "has to go somewhere," said study lead author Cornell University seismologist Katie Keranen.

Future legal challenge to a NY fracking ban may come from landowner

Following a court ruling backing the power of New York communities to ban fracking, lawyers are speculating that a future legal challenge could come from a landowner challenging the loss of valuable rights known as takings, E&E reports.

Fracking study finds new gas wells leak more

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 engineering professor Anthony Ingraffea, who heads an environmental activist group that helped pay for the study.
