Storm status, as of 10 a.m. CDT Friday, Oct. 9: Isaias was a Category 3 hurricane with 120 mph winds about 195 miles south of Pensacola, Florida, according to the National Hurricane Center, as reported by Rigzone. Landfall was expected on the western Florida Panhandle Friday evening. A storm surge warning covered the coast from the mouth of the Mississippi River in Louisiana east to Florida, AccuWeather reported.

A hurricane doesn't have to hit Louisiana to affect Louisiana's economy. Isaias is a good example: its forecast track stays east of the state's big refineries, yet most of the Gulf's offshore oil production was shut off ahead of it. Here's how that works.

Quick definitions. Shut-in production is oil or gas that operators deliberately stop pumping, usually by closing valves below the seafloor, so nothing leaks if equipment is damaged. A production platform is a fixed offshore facility. A dynamically positioned (DP) rig holds its place with thrusters instead of anchors, so it can move out of a storm's path with its crew aboard.

Offshore: the first thing to shut

As of 11 a.m. CDT Thursday, Oct. 8, operators reported, according to the Marine Minerals Administration:

MeasureFigure
Production platforms evacuated121 of 371 (32.6%)
Oil production shut inAbout 1.28 million barrels a day (62.9% of Gulf output)
Natural gas production shut inAbout 1.13 billion cubic feet a day (57.4%)
Non-DP rigs evacuated5 of 11
DP rigs moved off location4 of 17

The Marine Minerals Administration is the federal agency that, since July 10, combines the former Bureau of Ocean Energy Management and Bureau of Safety and Environmental Enforcement. It updates these figures daily at 1 p.m. CDT. Shell, Chevron and BP all reported shutting in production or moving workers onshore at several of their deepwater facilities, Rigzone reported.

Why shut in so much for a storm headed elsewhere? Platforms across the central Gulf sit in the storm's path at sea, where waves were forecast to reach 15 to 25 feet. Evacuating crews by helicopter takes days, so operators act early. For scale, Hurricane Ida in 2021 shut in about 96% of Gulf oil production at its peak.

The recovery is usually faster than the shutdown. After the storm, facilities are inspected, and "production from undamaged facilities will be brought back online immediately," the agency said.

Refineries: it depends on the track

Louisiana's large refineries, including those at Garyville, Baton Rouge, Norco, Chalmette and Meraux, sit along the Mississippi River west of Isaias's forecast landfall. The commodity pricing firm Argus said the track "would likely spare most of the refineries in Louisiana," and the hurricane center gave New Orleans and Baton Rouge less than a 3% chance of tropical-storm-force winds, Energy News Beat reported on Oct. 9.

The refineries closer to the path are next door. Chevron's Pascagoula refinery in Mississippi, a Vertex plant near Mobile and Hunt's refinery in Tuscaloosa together process nearly 500,000 barrels a day, Bloomberg estimated, according to Energy News Beat. U.S. diesel inventories were at their lowest for early October in federal records going back to 1982, which makes any refinery outage more noticeable.

Ports, rivers and the coast

Storm surge is the main coastal risk for southeast Louisiana in this storm. AccuWeather forecast some surge in Lake Pontchartrain, followed by a minor to moderate surge pushed toward New Orleans by northerly winds after the storm passes, and 1 to 6 feet of surge from the Florida Big Bend through southeast Louisiana. Ports and terminals typically restrict vessel traffic under Coast Guard port conditions as a storm approaches; check the Coast Guard's sector notices for current status.

Why this matters beyond oil

Louisiana's newer industries ride the same weather. The shipyards along U.S. 90 that are building Navy drone ships, the Port of Gulfport site where Saronic tests them, and the data centers going up across the state all plan around hurricane season. Each storm is a reminder of the questions worth asking about any large project here: how it protects its workers, how fast it can restart, and who pays when the grid goes down.

We'll update this story with production figures and any reported damage after landfall.
