As earthquakes continue to surge in Oklahoma and seismologists warn of more frequent and more damaging shaking, the state’s oil and gas regulator is issuing new orders to companies operating wells in seismically active regions of the state.

The Oklahoma Corporation Commission’s new requirements, known as directives, were mailed March 18 to 92 people or companies operating 347 Arbuckle formation disposal wells in quake-prone regions of the state.

As Authorities Use Permit Process to Scrutinize Wells, Oil Industry Remains Silent

As earthquakes continue to rattle Oklahoma and scientists study links to oil and gas production, many Oklahomans want to know what, if anything, is being done to address the shaking.

An investigation by StateImpact shows that while authorities are quietly scrutinizing wells in quake-prone parts of the state, most of the companies that operate the wells are staying silent.

Oklahoma’s earthquake surge is unrelenting. The shaking is rattling residents and cracking the foundations of homes.

The quakes have also strained state agencies, which are struggling to keep up with the ongoing swarm while simultaneously developing a longer-term plan to analyze and address factors that might be triggering the earthquakes.

High-Rate Disposal Wells Could Have Triggered Oklahoma Earthquakes, New Study Suggests

Joe Wertz / State Impact Oklahoma

This year, Oklahoma has had more earthquakes than California. There is a growing body of scientific research that suggests oil and gas production is fueling this increase in seismic activity.

new paper published today in the journal Science, suggests a small number of wastewater wells used in drilling operations could be responsible for many of the quakes.
