I took a TAOS damage estimate graphic and did a really rough overlay of Green Canyon, Miss Canyon, LOOP and the on shore facilities and came up with this:

Its entirely possible I have some or all of these in the wrong place but in general I think starts to depict the risk to the areas these facilities are located.

Whether outages are power related or damage related it seems highly likely that there will be impact to supply that lasts at least as long as Ivan.

mw, do you know anything about the modeling that's in the second update?

here's the link:

those are amazing numbers that are modeled on Ivan and other hurricane behavior.  experimental.  scary.

No, I'm just a consumer of this "info" like most - I can only speak from the mind of a trader (hopefully others will step in here and add their two cents) certainly this sort of modelling, if it has any track record at all, would be another influence in my decision process, pushing me to hold or add to long oil positions (and ensure I had no GOM exposure).
I do agree the damages can be of neverseen levels , and maybe will have the $100 scenario sooner then many tought , at least me... I did sold product on the sell off last friday , unfortanely I did close all my positons , but first thing in the morning(uk) , if track and assements still the same , it will be to get in long on crude and heat oil , because not just the damage will create, for sure will be severe ,but also the momentum build up for the bulls, which is already so high , and please don't make any confusion, i believe there is no fundamental reasons for the prices levels , I think they are over exagerated and are starting to making enormous damage to the world economy but the it take a while to feed trough, plus the time will take to assess all the possible damage will leave the market full of fear=high prices...the market did not priced in a major disruption like this...anyway just my humble opinion , what do you think the prices are going to? what are the consequences ...maybe the opening of spr , once state of emergency benn declared ?  
As I said in the post: check out those forecasted (and these are experimental) disruptions from that link:

57.3% of Gulf oil production is predicted to be cut for less than 10 days, 24% of oil production is predicted to be cut for 10-30 days.

That, folks, is a big deal if it's right.

... which means the graphic I did earlier (showing Green/Miss canyons, LOOP, Thunderhorse, Mad Dog, etc in the then-marked path of destruction) are now fully enveloped by either "widespread" or "severe" damage swaths...
and look at the new GOMEX predictions I posted.  (they just got updated with the new forecast).

http://hurricane.methaz.org/hurapak/AAL122005_gomex_oil.html  

Projected 91% disruption of oil production if the weather models are correct, 68% for 10-30 days, 24% for over 30 days.

Wow.  We're still 36 hours from landfall, but that is a daunting prospect.  

Oh my.

Clearly if the track holds up as the models are increasingly agreeing on, there is certainly going to be at least the short term impact as reality; I wonder how early the first offshore damage assessments will be known... Tuesday / Wednesday? Next week is going to be terrifically volatile while the post storm impact is assessed.

Beyond production facilities I wonder how much refinery capacity is at risk.

The current total for storm losses: 30B.

To put that in context, if accurate, its the most expensive hurricane in history. I think this just tells us it could be big, really big, but also not to wig out until more info is available...
