Subsidence Reports

Operators of salt caverns in Louisiana submit yearly subsidence reports to LDENR as a compliance requirement by the state. As part of an enhanced program to monitor ground subsidence at Sulphur Mines, Westlake was ordered by LDENR to provide more frequent updates and reports since January 2023.

The method used is InSAR, which employs satellites to approximate relative ground movement over time. Currently, one satellite (SNT) provides data every 12 days, and one satellite constellation (TSX/PAZ) provides data every 4 and 7 days, respectively.
