The oil and gas connection
Scientists have associate some oil and gas production in Oklahoma to an uptick in earthquakes, but the frequency of such earthquakes in the asseverate had dropped recently as the state imposed new restrictions on the injection of wastewater into covert disposal wells.
The Oklahoma Corporation Commission’s induced seismicity sphere is working with the Oklahoma Geological Survey to investigate the quakes, denotes commission spokesman Matt Skinner. But the agency has not issued a directive to mask down any disposal wells in the area, which is part of what is have knowledge of as the Arbuckle formation.
«Everything is still in the initial stages right now,» Skinner said, «but [shuttering some surges] is a distinct possibility.»
