With the corrosion of pipelines in Prudhoe Bay Field, the nation's largest oil field and the subsequent halting of oil shipments from BP PLc, the world's second largest petroleum company, oil prices have risen by $2.22 a barrel.
The Prudhoe Bay Field accounts for 8 percent of all U.S. oil production and serves the West Coast and its loss is most likely to affect California and neighboring states.
This new crisis will add to the already creeping inflation and further slow down growth in the US.
The corroded pipelines are an environmental threat and the extent of the problem became known when BP announced that 16 of their 22 Alaskan pipelines need to be replaced.
The shutdown of production could go on for months and will reduce US oil production by 400,000 barrels a day. Though the Bush government has come up with an alternative for refineries by offering oil from the 688 million barrels of Strategic Petroleum Reserve, analysts feel that it would be very difficult to ship that much oil to the West Coast in the absence of a pipeline.
A spokesman from the Energy Department however said that the high crude oil inventories would serve the refineries and there was no immediate need to dip into the Reserve. Despite this, gasoline prices are expected to rise by few cents or more a gallon.
There has been disagreement among experts about the impact of the Alaskan shutdown.
While few believe that the present loss would be a mere "blip" if supply of heavier crude oil from Saudi Arabia was stepped up for West Coast refineries, most experts are of the opinion that prices can be expectedto rise by $10 to $15 and that the longer the field remains shut, the higher the prices would go.
The situation has drawn a lot of negative attention on BP, which reported record earnings in the second quarter but has allowed extensive corrosion of a pipeline of such importance to the country.
Officials said that the oil pipelines being shut down were clogged by sludge buildup which may have prevented the most sophisticated internal corrosion tests.
While a device called a "scraper pig" was used to clean out the pipes of sludge in 1992, it is unclear whether another device called the "smart pig" which can detect pipeline abnormalities was used.
BP Alaska President said that the company is already in the process of adjusting their corrosion program.
Bob Slaughter, president of the National Petrochemical and Refiners Association, has a hopeful addition in that the US recovered from last year's hurricane caused supply disruption and "that was worse than this."
