Thirty-seven saltwater disposal wells in Oklahoma will cease operations by next Tuesday after a recent 5.6 earthquake--the state’s strongest in five years.
The earthquake rattled the region on Saturday, Sept. 3, though seismic activity continued through the Labor Day weekend and after.
The U.S. Geological Survey recorded two earthquakes on Tuesday, Sept. 6, that registered at 3.9 and 3.5 and struck less than 13 miles outside of Medford, Okla., near the Kansas border.
Saltwater disposal wells are used to dispose of fracturing flowback liquid and water collected from oil and gas production.
Bloomberg BNA reporter Paul Stinson says concern is building over Oklahoma’s potential seismic impact on its neighbors in his story 37 Oklahoma Disposal Wells Ordered Closed After Quake.
