ENID, Okla. — The Oklahoma Corporation Commission is taking action on disposal wells near Medford as a slew of earthquakes continue to shake the area.

According to a media advisory, the OCC has announced a plan to "reduce the risk of induced earthquakes" near Medford, which has had at least 23 earthquakes since Saturday.

The plan, focused on disposal wells injecting into the Arbuckle formation, calls for wells within 3 miles of the center of the earthquake activity to reduce volume injected by 50 percent, wells within 3 to 6 miles to reduce volume by 25 percent and wells within 6 to 10 miles to be on notice for possible coming changes.

Affected wells include three operated by Sandridge Exploration Production LLC, with one reducing volume by 50 percent and two reducing volume by 25 percent; one operated by Kirkpatrick Oil Company Inc., which will be shut in and have depth reduced before resuming operations at a 50 percent reduction in volume; three operated by Primexx Operating Corporation, with two reducing volume by 25 percent and one reducing volume by 50 percent; one operated by Union Valley Petroleum Corporation, which will reduce volume by 25 percent; and one operated by Special Energy Corporation, which will reduce volume by 25 percent.

The OCC plan has various deadlines, with all measures set to be taken by Dec. 7.
