Oklahoma Corporation implements plan following 5.0 magnitude earthquake in Cushing

OKLAHOMA CITY -- The Oklahoma Corporation Commission is implementing an action plan after a 5.0 magnitude earthquake shook Oklahoma Sunday night.

According to a press release, a total of 58 disposal wells that inject into the Arbuckle formation will be affected. The OCC says four of the wells were shut down in 2015.

A spokesman with the Commission says the plan is an initial response and operators are being warned that work is underway on a broader plan that will encompass a greater area.

Below is the initial plan released by the OCC.

There are 3 areas in the initial plan, at 6, 10, and 15 miles from the location of the 5.0 earthquake that struck the area Sunday evening.

  • 6 miles – all Arbuckle disposal well operations in the area must cease. 
  •  
  • 10 miles – all Arbuckle disposal wells must reduce volume by 25 percent of their last 30 day average.
  •  
  • 15 miles – all Arbuckle disposal wells in the area are limited in volume to their last 30 day average.
  •  
  • 15 of the Arbuckle disposal wells included in the latest directive have already been shut in by the September 3, 2016 directive.

Those wells that will have to take new action:

  • 7 Arbuckle disposal wells will be shut-in under the new directive.
  •  
  • 16 Arbuckle disposal wells will be reduced 25 percent in volume from their last 30 day average (Note: This is in addition to the 40 percent volume reduction that was  imposed earlier this year).
  •  
  • 59 Arbuckle disposal wells will be limited in volume to their last 30 day average (Note: This is in addition to the 40 percent volume reduction that was  imposed earlier this year).
