OKLAHOMA CITY (AP) — A SandRidge Energy injection well has been ordered shut down because of numerous earthquakes near the well in north-central Oklahoma.
The Oklahoma Corporation Commission issued the order Tuesday after a 4.1 magnitude earthquake was recorded in the area on Friday. The well is the second to be shut down since the commission began a new monitoring system in 2013.
Injection wells are used to dispose of wastewater produced from oil and gas wells. Several studies have linked injection wells and earthquakes. There are about 3,200 active injection wells in the state. In 2013, they moved about 1.1 billion barrels of wastewater.
Corporation Commission spokesman Matt Skinner told the Tulsa World (http://bit.ly/1xg19kf ) that SandRidge was operating with a permit that said the well would be shut down if there was any seismic activity.
SandRidge Vice President Jeff Wilson said the company is cooperating with the commission as it reviews the well near the Kansas border.
According to the newspaper, the commission held a hearing on Nov. 26 to discuss a SandRidge permit application after staff raised concerns about earthquakes in the area. The energy company had requested a permit to dispose up to 80,000 barrels of wastewater per day. It was later granted a permit to dispose of up to 40,000 barrels per day.
