9:05 a.m. Update

It has been reported to Assumption Parish Incident Command that their is 96′ of area left to be filled in the Oxy 3 cavern. The drilling operation on the Geophone 1 well to be installed into the salt begins today.

11:35 a.m. Overnight Breaches in Berm

Texas Brine’s western berm encountered five breaches overnight. Two breaches have been repaired, one breach is small and has not been repaired yet and two larger breaches continue to fill the sinkhole and containment area. Texas Brine has indicated that repairs will occur once water levels have stabilized.

10:30 a.m. Sinkhole Burp Reported

Early this morning, there was a burp in the sinkhole. Dr. Hecox has reported that seismic monitors recorded a VLP (very long period seismic signal) at 3:24 a.m. and it is likely that this is when the burp happened. The monitoring/alert status remains at Code 3, which means all work directly on the sinkhoke, Oxy 3 pad and within the containment berm is ceased until further notice.

12:15 p.m. Advisory from the Office of Conservation

The Office of Conservation, in consultation with Assumption Parish Incident Command, is advising the public that the Oxy 3/sinkhole monitoring alert status has been raised to Code 3 – requiring all work directly on the sinkhole, Oxy 3 pad and within the containment berm to cease until further notice. Seismic monitoring had detected a sustained increase in the trend of micro-earthquake (MEQ) activity in the area around the sinkhole and Oxy 3 over the past week, and a marked uptick in MEQs in the past day. This pattern of MEQ increase has been identified as an indicator of likely shifting and sloughing in the sinkhole and the area below it, based on past observations. The seismic activity is limited to the Oxy 3/sinkhole area, showing no indication of impact to the Oxy 1 area. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions.
