Gulf operators had shut in an estimated 1,282,879 barrels of oil a day as of 11 a.m. CDT on Oct. 8, while Hurricane Isaias closed in on the northern Gulf Coast, the federal offshore safety regulator reported. That is 62.89% of the Gulf’s current daily oil production, and natural gas is not far behind, with about 1,127 million cubic feet a day, or 57.35%, also stopped.
The totals come from a Marine Minerals Administration update posted Thursday on the Bureau of Safety and Environmental Enforcement’s website. Twelve companies filed the operator reports behind the 11 a.m. snapshot, and the agency says the figures will be refreshed daily at 1 p.m. CDT. The Marine Minerals Administration was formed July 10, 2026, when the Bureau of Ocean Energy Management and the Bureau of Safety and Environmental Enforcement were reunified.
For households, the open question is how much of that lost output and how many coastal refineries stay out of service long enough to move the pump. Bloomberg, in a report carried by Transport Topics, put the national average for gasoline at $4.36 a gallon on Oct. 7, with diesel near $6.28, after diesel set an all-time record in September. Anyone filling a tank on a fixed budget is watching the same two things: how long the shut-ins last, and whether the refineries nearest the storm keep running.
The offshore regulator will post a fresh shut-in total at 1 p.m. CDT each day, and Isaias is forecast to reach land late Friday or early Saturday.

What 62.89% says about the whole Gulf
The agency published percentages next to its volumes, which allows a quick back-of-the-envelope check. If 1,282,879 barrels is 62.89% of daily oil output, the Gulf was producing about 2.04 million barrels a day before the shut-ins, which leaves roughly 757,000 barrels a day still flowing. The same arithmetic on gas puts total output near 1.97 billion cubic feet a day, with about 838 million still moving. Those totals are calculations from the agency’s percentages, not figures it published.
A shut-in is a precaution, not damage. Operators stop production and move crews ahead of a storm, then restart once conditions allow. GasBuddy’s Patrick De Haan, quoted in the Bloomberg report, expects production to resume significantly by early next week once the storm passes. His Oct. 8 tally matched the agency’s: 62.9% of oil and 57.4% of natural gas shut down.
Three refineries in the storm’s path
Crude that stays in the ground matters less to a driver than gasoline and diesel that stop coming out of refineries, and Bloomberg counted nearly 500,000 barrels a day of refining capacity in Isaias’s projected path. The largest is Chevron’s Pascagoula, Mississippi, refinery at 356,000 barrels a day of crude, on the western edge of the Hurricane Center’s projected track as of Oct. 8. Chevron said it is monitoring the storm and making “appropriate preparations” at its onshore facilities.
Vertex Energy’s refinery in Mobile, Alabama, rated at 88,000 barrels a day, sits directly in the projected path. Hunt Refining’s Tuscaloosa, Alabama, plant, at 50,000 barrels a day, lies farther inland under a tropical storm watch. Neither company had answered Bloomberg’s request for comment. Together the three plants account for about 494,000 barrels a day.
De Haan also noted that the storm is moving away from roughly 2 million barrels a day of Louisiana refining capacity, a point that limits the exposure. Bloomberg added that oil markets were already under pressure from the war in Iran, so any extra outage lands on a market with little cushion.
Where the hurricane stands
The agency’s release is headed “Tropical Storm Isaias,” but the storm has strengthened since. In its 10 p.m. CDT advisory Thursday, the National Hurricane Center classed Isaias as a hurricane with maximum sustained winds of 105 mph and a central pressure of 969 millibars, about 260 miles south of the Mississippi River mouth and moving northeast at 14 mph. A turn north is expected Friday, with landfall late Friday or early Saturday inside a hurricane warning that runs from Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida.
Forecast storm surge reaches 5 to 7 feet from Dauphin Island, Alabama, to Indian Pass, Florida, if the peak arrives at high tide. Rainfall of 4 to 8 inches is forecast for southern Alabama, the Florida Panhandle, the Big Bend and southwest Georgia, with localized totals up to 15 inches. Surge and flooding are what threaten the onshore plants, which is why the refinery list matters as much as the offshore tally.
Tracking pump prices until the platforms restart
The cleanest way to follow the story is to compare each daily 1 p.m. CDT update from the offshore regulator with the last full count: 1,282,879 barrels of oil and 1,127 million cubic feet of gas shut in on Oct. 8. A falling share means crews are returning and wells are restarting; a rising one means more of the Gulf is idle ahead of landfall.
On the consumer side, the baseline is the $4.36 national average for gasoline and about $6.28 for diesel reported for Oct. 7. Price moves in the days after landfall will depend less on the offshore number than on whether Pascagoula, Mobile and Tuscaloosa take storm damage or lose power. Announcements from Chevron, Vertex and Hunt about restarts are the ones that carry the most weight for fuel supply along the Gulf Coast and inland.
The agency’s own table remains the benchmark for the offshore side: operators reporting as of 11 a.m. CDT on Oct. 8 had stopped 62.89% of oil and 57.35% of gas output.
