Earthquake shakes Oklahoma, wastewater injection wells ordered "shut in"

The Oklahoma Corporation Commission is ordering wastewater injection wells near this morning’s earthquake “shut in”. Arbuckle Oil and Gas has three wells within six miles of the epicenter of the 4.5 magnitude quake.

The quake was near Medford in Grant County, but was felt in Tulsa, Oklahoma City and Wichita. No damage or injuries were reported.

Wastewater injection, as part of the drilling process, has been linked to Oklahoma’s seismic activity.
