Storm Halts Gulf Oil Well Work

Informative story hot off the AP wire. Let's hope this system calms down and and the disruption is minimal.

"A storm brewing in the Caribbean brought the deep-sea effort to plug the ruptured oil well to a near standstill Wednesday just as BP was getting tantalizingly close to going in for the kill.

Work on the relief well - now just days from completion - was suspended, and the cap that has been keeping the oil bottled up since last week may have to be reopened, allowing crude to gush into the sea again for days, said retired Coast Guard Adm. Thad Allen, the government's point man on the crisis.

The cluster of thunderstorms passed over Haiti and the Dominican Republic on Wednesday, and forecasters said the system would probably move into the Gulf over the weekend. They gave it a 40 percent chance of becoming a tropical depression or a tropical storm by Friday.

Crews had planned to spend Wednesday and Thursday reinforcing with cement the last few feet of the relief tunnel that they hope to use to pump mud into the gusher and kill it once and for all. But BP put the task on hold and instead placed a temporary plug called a storm packer deep inside the tunnel, in case it has to be abandoned until the storm passes.

If the work crews are evacuated, it could be two weeks before they can resume the effort to kill the well. That would upset BP's timetable, which called for finishing the relief tunnel by the end of July and plugging the blown-out well by early August.

Even if the storm does not hit the area directly, it could affect the effort to contain the oil and clean it up. Hurricane Alex stayed 500 miles away last month, yet skimming in Alabama, Mississippi and Florida was curtailed for nearly a week.

The relief tunnel extends about two miles under the seabed and is about 50 to 60 feet vertically and four feet horizontally from the ruptured well. BP plans to insert a final string of casing, or drilling pipe, cement it into place, and give it up to a week to set, before attempting to punch through to the blown-out well and kill it."
