'Do not operate' quake-linked disposal wells -- EPA draft report
U.S. EPA officials say oil and gas wastewater injection wells that are causing earthquakes should stop operating if there's no way to stop the shaking. But there is a variety of other options to consider first, according to a "decision model" outlined in a draft report obtained by EnergyWire. That includes scaling back how much well owners can inject, requiring more data collection or public education about "the complexities of injection-induced seismicity."
Geologists link Okla.'s largest quake to injection wells
A 2011 earthquake that rattled Oklahoma and destroyed 14 homes was not only unusual -- it was probably unnatural, scientists say. Research published yesterday in the journal Geology links the quake -- the state's largest at magnitude 5.7 -- to underground injection of wastewater from nearby oil and gas production. It is the largest quake ever linked to injection.
States deciding not to look at seismic risks of drilling
Nine months after a National Academy of Sciences panel said oil and gas regulators should take steps to prevent man-made earthquakes, officials in key states are ignoring quake potential as they rewrite their drilling rules.
