Two natural gas exploration companies agreed to extend the shutdowns of two injection wells as researchers study if the wells are linked to a recent increase in earthquakes in central Arkansas. Chesapeake Energy Corp. and Clarita Operating LLC requested a continuance on hearings about the wells but the state oil and gas commission agreed only if the companies continued the shutdown of the two wells. The state seismologist says the area where the wells are located has experienced a noticeable increase in seismic activity since the injection wells closed in March.
