The Office of Conservation is advising Assumption Parish officials and the public in the Bayou Corne area that CB&I and Itasca Group analysis of ongoing seismic monitoring has detected what appears to be an uptick in underground fluid movement below the sinkhole in the vicinity of the failed Oxy 3 cavern in the past 24 hours. As has been noted in earlier similar events, the fluid movement appears to be linked to observations of trees falling into the sinkhole, release of trapped debris from the sinkhole bottom and increased odor from hydrocarbons released to surface. CB&I and Itasca Group analysts have advised that, while the activity appears to represent no additional significant threat to the general area, operations directly on the sinkhole be suspended until subsurface activity slows again.
