Hurricane Ida- Update #3

(ISSUED AT 9:00 PM CST): Shell continues to actively monitor Hurricane Ida in the Gulf of Mexico. As a precautionary measure, Shell has shut in production and evacuated all personnel from Ursa, Mars, Olympus, and Appomattox assets. In addition, production has been shut in and personnel will be evacuated from Auger and Enchilada/Salsa. Stones, which had earlier shut in production, is working to resume partial production, potentially as early as tomorrow. Some drilling operations have been safely paused.

We will continue to monitor weather reports and respond accordingly. As always, the safety of our people, the environment and our assets is Shell’s top priority.

Any personnel moved from or to our assets will continue to adhere to our existing COVID-19 risk mitigation measures. All personnel will be required to pass our COVID-19 screening process prior to returning to work offshore.
