Oil and gas producers, and refineries that fuel the U.S., are assessing the impact on operations after the passage of Hurricane Ida.

It could be quite some time before a full extent of the damage is known, with access to many facilities along the Louisiana coast still severely limited. Crews have been able to make aerial surveys, but roads are largely impassable due to high water and downed trees.

At least 2 million barrels a day of oil refining capacity was affected by the weather pattern, which cut power across Louisiana and left at least one facility in standing water. About 95% of oil production, and 94% of gas output had been shut-in as of Monday, according to the Bureau of Safety and Environmental Enforcement. 

Here is a list of major oil and gas production sites that were shut and their capacity in barrels per day, or barrels of oil equivalent a day.
