EDMOND, Oklahoma - The Oil and Gas Division of the Oklahoma Corporation Commission (OCC) is taking action in response to the earthquake activity in the Edmond area.

Officials said this is an ongoing response, and details on the most immediate actions should be available on Monday, January 4.

The issue is extremely complex, as the initial review of the data for the area in question has not identified any oil and gas wastewater disposal wells that are both high volume and in the state’s deepest formation, a combination that researchers have identified as being at the highest risk for inducing earthquakes, according to a news release from OCC.

OCC officials said it’s important to note that based on the data provided by researchers, the focus of the effort is directed at oil and gas wastewater disposal wells disposing into the Arbuckle formation, the state’s deepest formation. The source of most of the wastewater is not from hydraulic fracturing operations, but rather from producing oil and gas wells.

The wastewater is “produced” water; i.e., salt water that already exists underground and comes up with the oil and natural gas, officials said.
