The strongest earthquake ever recorded in Oklahoma may have been triggered by oil and gas activity that started and stopped years before the shaking, newly published research suggests.
Crude prices are on the rise, drilling activity is ramping up, and Oklahoma’s oil and gas regulator wants to limit the volume of wastewater energy companies pump into underground disposal wells, an activity scientists say is fueling the state’s earthquake boom.
The letter to Oklahoma’s three corporation commissioners is especially relevant because of Oklahoma Attorney General Scott Pruitt’s pending appointment to head the EPA, Ziva Branstetter reports. “Pruitt would be in a position to alter the EPA’s request and position on induced seismicity in Oklahoma. Such an action would impact energy companies here that have partnered [...]
Attorneys are asking a district court judge to approve a class-action lawsuit against oil and gas companies after a 5.0-magnitude earthquake rattled near the town of Cushing in November.
Attorneys are asking a judge in Pawnee County to approve a class-action lawsuit against oil and gas companies after the 5.8-magnitude earthquake that shook the area in September.
Wastewater injection into clusters of high-rate disposal wells likely triggered a 5.1-magnitude earthquake that struck western Oklahoma in February 2016, new research suggests. The earthquake near Fairview produced a large blast of seismic energy that spawned a series of widely felt aftershocks. The quake is now considered one of the largest ever linked to the [...]
Officials with the U.S. Environmental Protection Agency say Oklahoma oil and gas regulators should “consider a moratorium” of waste-fluid disposal in its most seismically active areas. The suggestion was made in the federal agency’s annual review of the Oklahoma Corporation Commission’s oversight of disposal wells, which Energy Wire’s Mike Soraghan obtained through a Freedom of [...]
Though the rate of earthquakes “has declined from its peak,” the 5.8-magnitude earthquake near Pawnee has made 2016 the most seismically active year on record “as measured by seismic energy release,” Oklahoma Geological Survey Director Jeremy Boak tells the Enid News‘ Sally Asher. Studying seismicity: Quake frequency declines, seismic energy in Oklahoma increases ENID, Okla. [...]
Oklahoma Regulators Expand Limits On Disposal Operations Near Labor Day Earthquake Federal and state regulators on Monday expanded and modified emergency orders limiting oil and gas activity at wells near a fault line that produced Oklahoma’s strongest earthquake on record. Regulators are targeting 67 disposal wells in two counties near the damaging 5.8-magnitude earthquake that [...]
The Sept. 3 earthquake near Pawnee, now considered Oklahoma’s strongest ever recorded, is the latest in a seismic surge researchers say has largely been fueled by the oil industry practice of pumping waste fluid into underground disposal wells.
