Oklahoma Temporarily Shuts Deep Disposal Well After Cushing Quakes

Seeking the cause of an increased number of small earthquakes, Oklahoma officials temporarily shut a disposal well that had been drilled too deep near the Cushing, OK, oil pipeline and storage hub (see Shale Daily, Oct. 15). While not assigning blame, they said the depth of the disposal well could have contributed to the outbreak of seismic activity.
