The agency says it notified the operators of five Johnson County disposal wells that they would need to shut down for tests on their operations.
The Railroad Commission says the tests are needed to determine if the wells have anything to do with seismic activity, and that the operators have agreed to shut down for testing.
The quake was strongest felt by North Texans in recent months. The U.S. Geological Survey measured the quake at a magnitude of 4.0.
It was recorded south of Fort Worth, between the towns of Venus and Lillian. People also reported feeling movement as far as Hillsboro, Fort Worth, Arlington and Dallas.
