Office of Conservation Orders Texas Brine To Assess And Abate Natural Gas In Bayou Corne Area
Order draws from scientific evidence that shows Texas Brine cavern failure led to crude oil and natural gas reaching surface
BATON ROUGE Louisiana Commissioner of Conservation James Welsh today ordered Texas Brine LLC to take action to assess and abate threats to public safety and the environment caused by the failure of its abandoned brine cavern on the west side of the Napoleonville Salt Dome, including the presence of natural gas in the area ground water aquifer.
In addition, Texas Brine is ordered to:
Maintain stability of pressure in the failed cavern to prevent additional changes to the cavern or sinkhole due to pressure changes
Install monitoring wells in the Bayou Corne community to monitor water quality and pressures, as well as elevation benchmarks within the community for subsidence monitoring
Install pressure monitor at wellhead of the cavern re-entry well, designed to provide real-time data to parish emergency response agencies of any rapid pressure change
Upgrade and expand seismic monitoring array to cover a wider area and include real-time data processing and interpretation of micro-seismic data, with seismic data reported in real-time to parish emergency response agencies
Install continuous water level monitoring station at the sinkhole
Collect and interpret geophysical data to determine the exact structure of the zone of failure and its impact on the surface and subsurface
Welsh said that the Office of Conservation is also continuing the effort, in coordination with Shaw Environmental, to establish and expand the array of observation/vent wells to provide for removal of natural gas found in the aquifer near the Bayou Corne community.
