(AP) – Oklahoma regulators say they will shut down some disposal
wells and reduce volume in others after a magnitude 5.0 earthquake struck near
Cushing on Sunday night.
The Oklahoma Corporation Commission’s Oil and Gas Division said Monday that
more than 700 square miles are included in the new area, but specific details
wouldn’t be released until Tuesday.
Wastewater from oil and gas production is injected into the disposal wells.
Scientists have linked the practice to the increase in earthquakes in Oklahoma
in recent years.
An official said Monday that 40 to 50 buildings sustained “substantial damage”
in Sunday’s quake.
Normal operations also resumed Monday at the Cushing oil storage terminal, one
of the world’s key oil hubs.
