TULSA — Two energy companies asked a judge Wednesday to throw out a lawsuit by an Oklahoma woman who claims she was injured in an earthquake caused by the injection of wastewater deep into the ground — a long-used method to dispose of the chemical-laced byproduct of oil and gas production.

The lawsuit by Prague resident Sandra Ladra alleges the companies are liable because they operated wastewater disposal wells that triggered the largest earthquake in state history, a 5.6-magnitude quake that hit in 2011. Ladra, who claims the quake crumbled her two-story fireplace and caused rocks to fall on her legs and gash her knee, is among others who have similar lawsuits pending elsewhere in the country.

Ladra is suing Oklahoma-based Spess Oil Co. and New Dominion LLC, as well as 25 unidentified parties. Her case was given new life in June when the Oklahoma Supreme Court overturned a decision by Lincoln County District Judge Cynthia Ferrell Ashwood, who had dismissed the suit on the grounds that the court didn't have jurisdiction in the matter.

Ashwood, who also presided over Wednesday's hearing, took the matter under advisement and did not issue an immediate ruling.
