A new study published in October purports to link seismic activity in Oklahoma to wastewater injection wells. Besides rates and pressures, Bridget Scanlon, hydrogeologist and lead author of the study, suggested injection depth may influence seismicity potentials. However, Scanlon limited her study to deep wastewater injection wells in Oklahoma.
The study examined the correlation between seismicity and wastewater injection wells in Oklahoma’s Arbuckle Formation—located adjacent to the basement. Additionally, the study noted seismic activity appeared to decrease in connection with reduced wastewater injection rates. According to the study, wastewater injection wells are the culprit of the increased seismic activity in … Continue Reading
