Hurricane Ida- Update #20

(ISSUED AT 10:00 AM CST) Shell continues to actively monitor the impact of Hurricane Ida to our assets in Louisiana and in the communities where we operate.

Following repairs to portions of our West Delta 143 (WD-143) offshore facility, operated by Shell Pipeline, we have safely and successfully re-started production at our Olympus asset in the Mars Corridor. The remaining assets in that corridor, Mars and Ursa, remain shut in. Our other Gulf of Mexico assets, Appomattox, Enchilada/Salsa, Auger, Perdido and Stones are all producing.

The Shell Norco Manufacturing Complex has completed damage assessments to the facility and has restored utility services to the site. We continue to make progress on our maintenance and repair activities in preparation to start up units beginning mid-October through mid-November. The site continues to flare residual light hydrocarbon material. Air monitoring is being conducted on the fence line and we are utilizing a 3rd party resource for air monitoring in the community. We will continue this monitoring throughout the duration of this event.

As always, Shell’s top priority is the safety of our people, the environment, and our assets.
