Clyde earthquake directive

The Oklahoma Corporation Commission’s Oil and Gas Conservation Division today issued a formal directive in its continuing response to the 4.5 earthquake that occurred Monday, January 31, in the Clyde area of Grant County.

Under the directive:

• Arbuckle oil and gas wastewater disposal wells operating within six miles of the earthquake’s epicenter will be shut down indefinitely.
  • There are seven wells in all, with four currently injecting.
• Arbuckle disposal wells operating within six to 10 miles of the earthquake’s epicenter will be restricted to their 30-day reported average volume, or 500 barrels a day, whichever is less.
  
  

The Arbuckle is the state’s deepest formation.
