"At least 20 oil rigs and platforms are missing in the Gulf of Mexico and a ruptured gas pipeline is on fire after Hurricane Katrina tore through the region, a US Coast Guard official said. "We have confirmed at least 20 rigs or platforms missing, either sunk or adrift, and one confirmed fire where a rig was," Petty Officer Robert Reed of the Louisiana Coast Guard told AFP.
There are MANY production platforms missing (as in not visible from the air). This means they have been totally lost. I am talking about 10's of platforms, not single digit numbers. Each platform can have from 4 to 100+ wells on it. Most larger ones have 20-30 wells in this area, with numerous caisson wells. They are on their sides, on the bottom of the gulf - they will likely be left as reef material, provided we can get permission. MMS regulations require us to plug each of the wells that were on these platforms - HUGE cost now, as the platforms are gone... Hopefully, MMS will grant `abandon in place' status for these wiped out structures.
In short, the Gulf area hit by the storm is basically in about the same shape as Biloxi. The damage numbers you have gotten from the government and analysts are, in my opinion, much too low. We are looking at YEARS to return to the production levels we had prior to the storm. The eastern Gulf of Mexico is primarily oil production."
