The storm swept through key offshore oil and gas production zones and made landfall in Louisiana as a Category 2 hurricane last Wednesday. It left a trail of destruction, uprooting trees, flooding coastal regions, and causing widespread power outages across four southern states.

On Sunday, energy companies reported that 338,690 barrels per day of crude oil and nearly 515 million cubic feet of natural gas production remained offline in Gulf waters. The Bureau of Safety and Environmental Enforcement (BSEE) shared these figures based on data provided by producers.

The cumulative losses due to the storm are significant, with total offshore production declines reaching 2.16 million barrels of crude oil and 4.635 billion cubic feet of natural gas, according to a Reuters summary of BSEE's daily estimates.

On Sunday, 37 oil and gas platforms remained evacuated, roughly 10% of the Gulf of Mexico's total. This marked a sharp decrease from the 171 platforms that had been evacuated at the peak of the storm's impact last week, as reported by the offshore regulator.
