Why Class II Injection Wells are Safe

Protecting Our Environment. Protecting Our Communities.

"Safe disposal of the salt water fluids, brine, that’s produced during oil and gas production is crucial to protect our groundwater."

Wasterwater is:
  • Returned to the confining geologic layers where it occurs naturally.
  • Only injected into the geologic strata where the water is not suitable for drinking.
Class II Injection Wells are:
  • Constructed using several layers of protective materials, including steel and cement.
  • Highly regulated by the Environmental Protection Agency.
  • Closely monitored by permitting agencies.
  • Regularly inspected by Penneco Environmental employees.
Penneco Environmental Solutions:
  • Performs Mechanical Integrity Tests to ensure that our wells are mechanically sound.
  • Monitors injection rates, volumes, and pressures to assure structural and operational safety.
  • Reports monitoring data to regulating bodies and permitting agencies.

Class II Injection Wells have been the preferred way to dispose of fluids produced during oil and gas production for decades.

Did You Know
  • Deep underground injection has been identified as one of the safest ways to manage wastes [fluids produced along with oil and gas].
  • They include both flowback water and brine (deep water found naturally in geologic formations).
  • The history of underground disposal shows that it is a practical, safe and effective method for disposing of fluids from oil and gas production.
  • Industry compliance monitoring organizations like the American Petroleum Institute organizations like the Interstate Oil and Gas Compact Commission prefer injection wells to other means of wastewater disposal because the wastewater is returned to where it originated, thus eliminating the need to find an alternate disposal location
