Small earthquake results in temporary shutdown of completion of Canadian County well


A small earthquake early Thursday morning near Union City in Canadian county resulted in state regulators enforcing their earthquake mitigation plan and the temporary shutdown of a well completion process.

The reported 2.2 magnitude quake followed a series of weaker rumblings. Under the mitigation plan created some years ago by the Oklahoma Corporation Commission, it is to be enacted after a 2.0 magnitude reading.

Regulators enacted the plan and as a result, Paloma Resources paused the completion operation for a reported 6-hour period.

The Oklahoma Geological Survey indicated the quake was one of four recorded in the past 24 hours in an area northwest of Union City. The strongest, recorded by the OGS at 2.1 magnitude, was about 6 miles from the city and its epicenter was about one mile west of the El Reno Municipal airport.
