Singapore - Crude prices surged in Asia on Monday as supply of oil and gas from the Gulf of Mexico was curtailed after tropical storm Isaac forced the closure of production facilities in the region, analysts said.
New York's main contract, light sweet crude for October delivery soared $1.03 to $97.18 a barrel in the afternoon and Brent North Sea crude for delivery in October gained $1.25 to $114.84.
The shutdown and evacuation of personnel from production facilities in the Gulf of Mexico due to Isaac was fuelling a crude rally, said Victor Shum, senior principal of Purvin and Gertz energy consultants in Singapore.
"In the Gulf of Mexico there is this tropical storm... that's threatening the region and has already caused some precautionary shut down of the production facilities there," he said.
"And so (this) is the main factor supporting oil at this point," Shum added.
The Gulf of Mexico is the hub of US offshore energy production, accounting for 23% of US crude oil output and 7.0% of US natural gas production.
The Gulf coast's facilities also have more than 40% of total US petroleum refining capacity and 30% of natural gas processing plant capacity.
BP said Sunday it was shutting down production at all of its oil and gas platforms in the Gulf of Mexico and evacuating all staff amid forecasts that Isaac was set to strengthen into a a category two hurricane.
The shutdown includes BP's Thunder Horse platform, the world's largest offshore production and drilling facility, which has a capacity of 250,000 barrels of oil and 200 million cubic feet of natural gas per day.
Chevron - the second-largest oil producer in the Gulf of Mexico behind BP - also said Sunday it was evacuating staff from some offshore facilities.
Royal Dutch Shell said it was preparing for evacuations of non-essential personnel from platforms and had suspended some drilling operations.
Meanwhile, three US Gulf Coast states also declared states of emergency on Sunday as Isaac barreled towards land, threatening to slam into Louisiana as a damaging hurricane.
The governors of Louisiana, Mississippi and Alabama issued their declarations as Florida, which went on a state of emergency a day earlier, was drenched by heavy rains and strong winds from the storm.
