Hurricane Isaias Disrupts Gulf Oil Production

For drivers in the U.S., it’s a classic case of “when it rains, it pours.” Just when it seemed that the hurricane season was going quietly, Hurricane Isaias arrives towards the end of the season, causing significant disruptions in oil production across the Gulf of Mexico and possibly pushing several refineries to halt operations temporarily.

This situation is likely to lead to renewed upward pressure on gasoline and diesel prices after a couple of weeks of gradual decline from highs not seen since 2026. The U.S. Marine Minerals Administration (MMA) reported that nearly a third of the 371 oil production platforms in the Gulf had to be shut down and evacuated to ensure the safety of personnel and infrastructure due to the storm.

Regrettably for consumers, Isaias is moving through some of the most productive oil areas, and those shut-down platforms account for about 63% of the Gulf’s total crude production. The MMA estimates that for at least a few days, the storm could remove around 1.3 million barrels of oil per day from the refining and distribution supply chain, which translates to nearly 10% of the country’s total output. Some platforms may resume operations quickly after passing safety checks, but others that incur damage will remain offline for a longer period.

The decreased supply of crude oil means there will be less refined gasoline and diesel available for the short term, leading to a rise in pump prices, reversing the recent downward trend. It’s just how the market responds.

When it comes to refining, there’s a mix of good and bad news. On the bright side, Isaias’s path is east of the major refinery cluster along the Mississippi River, stretching from Baton Rouge to New Orleans—an area that significantly contributes to the Gulf Coast refining landscape in Texas and Louisiana. However, it’s important to note that a few refineries lie directly in the hurricane’s path.

The following refineries were positioned in or near Isaias’s expected route as of Friday afternoon:

• Chevron’s Pascagoula refinery in Mississippi, with a capacity of about 356,000 barrels per day, is on the western edge of the storm’s cone. Chevron is monitoring the storm and following its storm-preparedness plan, with no announcements regarding shutdowns.
• Vertex Energy’s plant in Saraland/Mobile, Alabama, which processes around 88,000 barrels per day, is directly in the storm’s projected path. There hasn’t been any comment from the company lately.
• Hunt Refining’s Tuscaloosa refinery in Alabama, with a capacity of approximately 50,000 barrels per day, is further inland and under a tropical storm watch, though it remains in the broader forecast path. Hunt had not provided any updates at the time of this writing.

For the best outcome, it would be ideal for these refineries to keep operating despite the storm’s threats. Of the three, Chevron’s operation in Pascagoula appears to be the safest as it sits slightly east of the expected path. Its significant capacity ranks it as the 11th largest in the nation, and because it produces gasoline, jet fuel, and diesel, it represents the largest potential disruption among the three facilities.

Interestingly, although crude oil prices saw some easing in trading early this week, wholesale diesel and gasoline prices seemed to be heading in the opposite direction as Isaias approached landfall. By Thursday, November diesel futures (ULSD) closed at $4.8829, up about 26 cents, while gasoline futures (RBOB) rose around 8 cents to $3.3160. These wholesale price increases are likely to quickly reflect in retail prices at the pump, though that may only last temporarily.

This situation certainly comes at a difficult time, as Andy Lipow, president of Lipow Oil Associates LLC, pointed out the low inventory levels for gasoline and diesel in a statement on Wednesday. His observations are hard to dispute.

Ultimately, this scenario highlights the reality that nature has a significant influence on the market. No amount of legislative action, executive orders, or regulations can completely mitigate the impact that a single hurricane can have on prices for gasoline and diesel, at least in the short term. As Walter Cronkite might have said, that’s just the way it is.
