A district court judge has approved class-action status for a lawsuit accusing an Tulsa oil company of being responsible for damage caused by earthquakes.

The judge ruled that residents and business owners with property in nine counties — Cleveland, Creek, Lincoln, Logan, Okfuskee, Oklahoma, Payne, Pottawatomie and Seminole — can join a 2015 lawsuit brought by resident Jennifer Lin Cooper after a string of earthquakes shook near the city of Prague in 2011.

The lawsuit accuses New Dominion of operating wastewater disposal wells that triggered the shaking, which peaked with a 5.7-magnitude earthquake that injured two people and damaged more than a dozen buildings.

New Dominion President and General Counsel Fred Buxton declined to comment on the pending lawsuit, but the company has denied causing the earthquakes in court filings.

The Prague earthquake was the first Oklahoma temblor scientists linked to the energy industry practice of pumping oil-field wastewater into underground disposal wells.

Trial is set to begin in September. Attorney Scott Poynter, who represents Cooper and the class of plaintiffs, expects trial to last two weeks.
