LP and Stephens Energy Group LLC, took the actions voluntarily, the commission said. The three disposal wells are northeast of Crescent.Stephens shut in its Chambers disposal well and reduced injected volumes 50 percent at its Cat in the Hat disposal well.Devon shut in its Hopfer disposal well, which is about a mile east of Stephens’ Cat in the Hat well.The companies either declined to comment or didn’t return calls Tuesday.More than a dozen other disposal wells are within a 6-mile radius of the earthquakes near Crescent, according to commission data.Those wells are under previous commission directives to either shut in or prove they aren’t injecting through the deep Arbuckle formation into the crystalline basement.Several recent studies have linked injection wells that touch the basement to some of the recent earthquake activity in Oklahoma.Stephens’ Chambers disposal well was added earlier this month to an updated list of wells under increased scrutiny from commission<a href="http://newsok.com/three-disposal-wells-change-operations-after-earthquakes/article/5436778" target="_blank">http://newsok.com/three-disposal-wells-change-operations-after-earthquakes/article/5436778</a></blockquote>
