Earthquake risks prompt evaluation of wastewater injection

Earthquake risks recently prompted lawmakers and regulators in several oil and gas producing states to evaluate wastewater injection purportedly linked to seismic activity. Key developments include:
  • 4/21: SMU faculty publish geophysical report blaming two wells for Azle, Texas quakes
  • 4/23: US Geological Survey issues report claiming seismic events in 8 states were induced
  • 4/23: Oklahoma Geological Survey issues statement saying seismic events unlikely to be natural
  • 4/24: Texas Railroad Commission issues public statement that it will order show cause hearings for the two Azle wells
  • 5/4: Researchers and Railroad Commission officials testify before Texas House Energy Resources Committee induced seismicity hearing
Review a discussion of legal issues associated with induced seismicity.

We will continue to monitor breaking developments here at The Hydraulic Fracturing Blog.
