Two Injection Wells Shut Down After Oklahoma Quakes
Oil and gas operators shut down two wastewater injection wells in northern Oklahoma on 28 July and reduced operations at a third after several earthquakes centered in the town of Crescent rattled the state
Stephens Production and Devon Energy each voluntarily closed one well, and Stephens reduced operations at another well by 50%, Oklahoma Corporation Commissioner Matt Skinner said.
“In this case, we didn’t have to issue a directive. We simply called them up and said what we were looking at,” Skinner said. “In terms of fast cooperation from the industry, there’s always exceptions to the rule, but broadly speaking we’ve had very fine cooperation.”
Crescent is a town of about 1,400 people approximately 35 miles north of Oklahoma City. Earthquakes in the area recorded by the US Geological Survey include a magnitude 4.5 quake at 1:12 p.m. Monday that is the strongest reported in the state so far this year. In all, more than 15 temblors of magnitude 2.0 or stronger were reported on 27 July by the Oklahoma Geological Survey. An additional nine quakes ranging from 2.2 to 4.1 were recorded through the early evening of 29 July.
There were no immediate reports of injuries or damage in the area, although people reported feeling the 4.5 quake as far as 650 miles away in Indiana and Minnesota, according to the USGS.
