Westlake Sulphur Dome & Other Information

Westlake's Statement - 9/20/2023

Westlake Corporation’s Lake Charles operations have been actively investigating, managing, and responding to the condition of one of the company’s salt caverns located in the Sulphur, Louisiana area. 

Since January 2023, Westlake has been working diligently with the Louisiana Department of Natural Resources (DNR) to address the situation. Westlake immediately started engaging third party experts (e.g., seismologists, geophysicists, geo-mechanical engineers) to assist Westlake in understanding the situation and to provide us advice on how to best address it, including brine injection into the well, which has stabilized cavern pressure.  We also have continued to work with the DNR on any developments, additional observations, and to mobilize additional resources and services to anticipate and respond to any circumstances that may arise.
