Backlash of Fracking in Oklahoma After Record Quake Could Slow Shale Play Development

A record-tying earthquake that shook Oklahoma and was felt in six other states on Saturday may bring more backlash against hydraulic fracturing, which could possibly slow down development of some U.S. shale plays.

The 5.6-magnitude tremor was felt from Texas all the way to Illinois, tying with a record in 2011. Last year, 890 earthquakes were recorded as 3.0 or higher, a significant increase from a 2008 recording of only two earthquakes at 3.0 or higher, which occurred before the state’s fracking boom.

With an oil production increase in Oklahoma came an increase in wastewater disposal wells. As drilling companies use fracking methods to break up rock and extract oil, large quantities of wastewater are produced as a result. Drilling companies then inject the water into deep wastewater wells.

Many earthquakes in the state have been triggered by wastewater injection, and the Oklahoma Corporation Commission has been issuing restrictions over the last year to reduce the amount of wastewater injected into wells.

The weekend earthquake led the commission to suspend 37 wells in the state.

President of Strategic Energy and Economic Research in Winchester, Massachusetts Michael Lynch said: “[Oklahoma is] going to push the industry to come up with some permanent solutions. It’s hard to believe Oklahoma would ban fracking, but I can see where they would say to people that they have to do something else with the wastewater, which is believed to be the source of the increase in earthquakes,” according to Bloomberg.


Oklahoma Corporation Commission Reports Several Failures Prior to Gas Explosion

Oklahoma Corporation Commission reported Wednesday that Oklahoma Natural Gas failed to investigate the cause of at least eight previous failures on a gas main in an Oklahoma City neighborhood before a gas explosion in January damaged 50 houses and injured one man.

According to the report, the technician did not properly investigate an odor complaint made approximately 12 hours before the explosion occurred on January 2, 2016.

The commission reported earlier this year that the explosion was caused by poor workmanship on the line that was installed in 1983.

Spokesman for the commission Matt Skinner said actions following the violations could include a court case or fines.

Oklahoma Natural Gas is currently reviewing previous testing and maintenance made throughout its entire system and expects to finish by the end of the year.
