Hurricane Isaias is already causing significant disruptions in the energy industry in the United States. Oil companies have proactively suspended 25.08% of crude oil production in U.S. Gulf waters, a reduction that could put pressure on the fuel market if it continues over the coming days.
According to the official report published on Wednesday, October 7 by the Marine Minerals Administration (MMA), the suspension amounts to 511,619 barrels of oil per day, while 16.37% of the regional natural gas production also remains interrupted.
The measures were adopted while Isaías was still a tropical storm. Hours later, the National Hurricane Center (NHC) confirmed that the system had reached category 1, with maximum sustained winds of 120 kilometers per hour.
The concern now is that the energy disruption will extend and impact fuel supply chains, especially in states like Florida, which heavily rely on maritime shipments of gasoline.
More than half a million barrels per day cease to be produced
The MMA, the federal agency responsible for overseeing maritime energy activities, confirmed that the companies had evacuated workers from eight production platforms, accounting for 2.16% of the 371 inhabited facilities of this type in U.S. Gulf waters.
Personnel from two drilling teams were also evacuated, and a unit with dynamic positioning moved out of the risk area.
The suspended natural gas production reached 350.25 million cubic feet per day.
The figures correspond to the reports received by federal authorities until 11:00 a.m. on Wednesday, Central Time in the United States, and represent estimates of the production that companies expected to extract during that day.
The temporary suspension of wells is a common safety procedure in the event of an approaching hurricane. It does not mean that the facilities have suffered damage or that this production has been permanently lost.
The agency explained that once the cyclone has passed, the companies will inspect their facilities and will be able to resume operations in those that show no damage. The affected platforms may require additional time to become operational again.
Shell and Chevron scale back their operations in response to Isaías
Among the major companies that have adopted preventive measures are Shell and Chevron, two significant players in the U.S. oil industry.
According to Reuters reported on Wednesday, Shell announced the evacuation of personnel and the suspension of production at its Mars, Olympus, Ursa, Vito, and Appomattox facilities.
The company had also previously relocated non-essential workers from its Stones facility to land.
For its part, Chevron announced that it had begun suspension procedures for production at four facilities it operates in the Gulf, while maintaining normal operations at five others.
These measures reflect the industry's concern about the possible intensification of the hurricane, whose winds, swells, and sea conditions may compromise the safety of workers and infrastructure.
Could gas prices increase in Florida due to Hurricane Isaias?
The suspension of a quarter of the U.S. offshore oil production in the Gulf raises a particularly important question for drivers in Florida: Will there be a new increase in gas prices?
For now, there is no proven relationship between the disruptions caused by Isaías and a specific increase in state pump prices.
According to AAA data as of October 7, the average price of regular gasoline in Florida was about $4.19 per gallon, still below the level recorded a week earlier.
However, a prolonged interruption of oil production could add pressure to crude prices, especially if it coincides with other supply issues.
The evolution will depend on how long the facilities remain shut down, whether the hurricane impacts the refineries and distribution terminals, and the overall behavior of international oil markets.
Therefore, it cannot be assumed that gasoline will increase in price immediately, nor can it be determined how much it might rise.
Why Florida is especially vulnerable to supply issues
Florida has a characteristic that makes the evolution of the hurricane particularly important: it does not have its own refineries and relies heavily on fuel transported by ship from other regions of the United States and international markets.
The U.S. Energy Information Administration (EIA) has explained that a significant portion of the gasoline consumed in Florida arrives through ports such as Tampa, Port Everglades, Jacksonville, and Port Canaveral, from where it is distributed to various areas of the state.
The institution has also documented how previous hurricanes disrupted port operations, shipping routes, and distribution chains, causing temporary supply difficulties.
In an analysis of hurricane risks for the refining industry, the EIA noted that the Gulf holds a crucial part of the U.S. refining capacity.
Thus, the economic consequences of a hurricane do not depend solely on the oil wells that stop producing. It also matters that the refineries, ports, and transportation systems can continue to operate.
If Isaías causes prolonged shutdowns or difficulties in distributing fuels, there could be price increases or localized supply issues. However, that scenario remains a possibility, not a confirmed consequence of the current disruption.
What will happen to oil production after the hurricane?
The main factor will be the speed at which companies can inspect and reactivate their facilities once the danger has passed.
If most of the platforms resume operations without significant damage and fuel transportation remains stable, the impact on supply could be limited.
On the other hand, if damage is recorded in the infrastructure, power outages, or prolonged interruptions at refineries and ports, the consequences for the energy market could last longer.
As a precedent, the EIA has documented that hurricanes Harvey and Irma caused significant disruptions in the supply and price increases of gasoline in Florida during 2017, although the current conditions are different.
CiberCuba reported this Thursday that Isaías has become the first hurricane of the Atlantic in 2026, with hurricane warnings and storm surge advisories for areas along the northern Gulf coast.
The threat has also led Florida authorities to order evacuations and announce airport closures in areas of the state's northwest.
As the hurricane approaches, the energy sector remains vigilant regarding its trajectory as well as the subsequent inspections, which will help determine how long oil production will be halted.
For Florida residents, the crucial detail over the next few days will be whether the disruptions also affect gasoline supply to service stations or are limited to a temporary halt in maritime operations.
