Reuters: Colorado regulators said on Thursday that the disposal of oil and gas wastewater at a well in Weld County likely caused a series of small earthquakes this year, in another sign that a U.S. drilling boom is contributing to higher seismic activity. The issue of wastewater disposal disturbing underground faultlines has become a national issue in the United States where drilling and wastewater disposal have increased sharply in recent years. The Colorado Oil and Gas Conservation Commission (COGCC)...

Study finds that quakes tied to drilling

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 of water a mile or two underground into rock formations, the...
