Oklahoma City-based SandRidge Energy is the latest company to be included in a federal lawsuit concerning induced earthquakes.
The Oklahoma Chapter of the Sierra Club and Public Justice amended their lawsuit Wednesday to include SandRidge. The two organizations filed the original lawsuit in mid-February naming Devon Energy Production Co., Chesapeake Operating LLC and New Dominion LLC.
In the lawsuit, the Sierra Club and Public Justice seek an order requiring the four energy companies to immediately reduce the amounts of waste water they are injecting into disposal wells. The groups also want an independent scientific body to be formed to oversee research and response actions related to injection wells. Finally, the suit asks for a public study looking at infrastructure that might be threatened by on-going earthquakes.
