PAWNEE, Okla. – More disposal wells near Pawnee will be shut-in following the 4.3 magnitude quake that struck the area earlier this week.

Following a second large earthquake in the Pawnee area, the Oklahoma Corporation Commission announced a new plan of action.

"Through these last few years, the damage has mounted time after time, earthquake after earthquake,” said Jackie Dill, a Murrow resident.

Dill is one of dozens affected by a recent outbreak of earthquakes near Pawnee.

"The estimate for doing the repairs, they were going to have to take everything out of my house. They were going to have to take all of the floors out, cabinets, bathtubs, everything. The only thing left standing in the house was the interior walls and exterior walls,” said Lisa Griggs, another earthquake victim.

After the 5.8 magnitude quake rattled Pawnee and surrounding areas in early September, the OCC shut down many disposal wells.

"This latest action covers a total of 38 Arbuckle disposal wells. It's Arbuckle disposal wells that have been focused on by researchers that say that's where the highest risk is for earthquakes,” said Matt Skinner, a representative for the OCC.

However, some of those well have already been shut-in following the first large quake.

"We have it divided up into 6 miles, 10 miles and 15 miles around the location of the 4.3 earthquake that struck,” Skinner said.

Arbuckle disposal wells within six miles will stop operations, within 10 miles must reduce volume by 25 percent of their last 30 day average, wells within 10 miles must reduce volume by 25 percent of their last 30 day average, wells within 15 miles are limited in volume to their last 30 day average.

"We're going to keep going forward with this response. This is a very, very serious situation,” Skinner said.

A total of four new Arbuckle disposal wells be shut-in under this new directive.

10 Arbuckle disposal wells will be reduced 25 percent in volume.
