The Oil Drum

BP expects to replace 73% of Prudhoe pipelines now.

Here's the first Prudhoe Bay thread.

Because of severe corrosion in one of the pipelines, BP is temporarily closing the production from the Prudhoe Bay oilfield, and, in the process, cutting off some 400,000 barrels of oil a day, some 8% of US production. The NYT story suggests that this might raise prices by as much as $10 a barrel.

ANCHORAGE, Alaska - In a sudden blow to the nation's oil supply, half the production on Alaska's North Slope was being shut down Sunday after BP Exploration Alaska, Inc. discovered severe corrosion in a Prudhoe Bay oil transit line.

BP officials said they didn't know how long the Prudhoe Bay field would be off line. "I don't even know how long it's going to take to shut it down," said Tom Williams, BP's senior tax and royalty counsel.

Once the field is shut down, in a process expected to take days, BP said oil production will be reduced by 400,000 barrels a day. That's close to 8 percent of U.S. oil production as of May 2006 or about 2.6 percent of U.S. supply including imports, according to data from the U.S. Energy Information Administration.

and then let's not forget:

OPEC production down in July 0.8%.

Tomorrow will be an interesting day. More under the fold.

UPDATE: From Rigzone

The Department of Energy Monday said it would consider offering refiners oil from the nation's emergency oil stockpile to address supply concerns in Alaska resulting from BP's shutdown of Alaska's Prudhoe Bay field.

If one  further looks at the numbers that the EIA site provides. There is a slight discrepancy between the tabulated data and that plotted, and it took me a minute to realize that the curves are showing the rolling four-week averaged data, rather than the actual weekly for the imported gasoline data (and presumably also for the rest).  This is of significance since such an average, in this case with the changing situation, initially masks the fact that the imports for the past three weeks have gone from 0.938 to 1.207 to 1.423 mbd.  One may assume (at least I am) that about 500,000 bd of this is coming from the 20 mbd of gasoline that was put up by the IEA partners in response to our request following Katrina.  If this is the level of support that can be anticipated, then it will last some 40 odd days before that source is gone.
