Recent reports show that disposal well operators placed about 23 percent less saltwater from oil and natural gas production into Oklahoma's deepest geological formation within the earthquake zone in 2016 compared to the previous year. The year-end reports about the Arbuckle formation come from the Oklahoma Corporation Commission. The commission says the 2016 volume numbers are mostly complete, though some companies haven't reported their latest data.
