Earthquakes

The Oklahoma Corporation Commission (OCC) has ordered two disposal wells to stop operations and for another three wells to reduce their disposal volume after analyzing disposal well and seismicity data in the Cushing area, the agency said Friday.

Oil and natural gas operators need to cut back on waste fluids that are injected into wells to help reduce the outbreak of small earthquakes, which are occurring with increasing frequency in the Midcontinent, according to two recent studies.

After a 4.0-magnitude earthquake in North Texas on Thursday, four area drilling waste disposal well operators have shut down operations at five wells while data on seismicity in the area is collected. Meanwhile, Oklahoma injection well operators are living in a different world following quake-minded regulatory initiatives.

Last week's initiation of a show cause order by the Railroad Commission of Texas (RRC) against operators of drilling waste injection wells thought to be linked with earthquakes in the Barnett Shale region was a dramatic and unusual step, an environmental lawyer with RRC experience told NGI's Shale Daily.
