Shell, Chevron Reduce Gulf of Mexico Oil Output Amid Tropical Storm Threat

Oil Companies Respond to Approaching Tropical Storm Isaias

Shell's Offshore Operations and Evacuations

Oct 7 (Reuters) - Shell and Chevron said on Wednesday they were curtailing offshore operations in the Gulf of Mexico as Tropical Storm Isaias approached the region.

Shell said it was evacuating all personnel and shutting in production at its Mars, Olympus, Ursa, Vito and Appomattox assets. The company added that it had already moved non-essential personnel from its Stones asset.

Chevron's Precautionary Measures

Separately, Chevron said it had initiated shut-in procedures for production at four Chevron-operated Gulf of Mexico facilities in preparation for the storm.

Personnel Safety and Production Status

The US oil major added that some additional personnel were being transported onshore, while production at its other five Gulf of America, referring to the Gulf of Mexico, facilities remained at normal levels.
