Thad Allen Will No Longer Give Timeline Plugging Well

NEW ORLEANS (AP) - The government's point man on the Gulf oil
spill said Wednesday he is no longer giving a timeline for
completing the final stages of plugging BP's runaway well.
Retired Coast Guard Adm. Thad Allen told reporters that he will
give the order to complete the so-called relief well when he is
ready. Since nearly the start of the disaster in April, the plan
had been to complete a relief well by early to mid-August. But
stormy weather and now questions of how to mitigate risks have
delayed that timeline.
Allen said BP PLC still needs to come up with a plan to
alleviate pressure that may build up once the relief well
intersects the runaway well.
Ultimately, the plan is to pump mud and cement into the runaway
well from the bottom to plug it permanently.
Allen said he doesn't want to give timelines anymore because if
he has to change them, that could cause a credibility problem.
"We will know when we have satisfied ourselves and we have
removed any shadow of doubt," Allen said when asked at what point
he would give the order to move forward. He said the pause is
"nothing more than an overabundance of caution and doing our
The two options for relieving pressure are either to design a
mechanism to attach to the current blowout preventer and temporary
cap that has been preventing oil from entering the Gulf since
mid-July, or to replace the existing blowout preventer with a new
one first and then proceeding with the relief well.
John Wright, who has been leading the team drilling the relief
well aboard a rig at the wellsite, said he also has not been given
an exact timetable.
"I was told they are working through risk and contingency plans
and would let me know when they were ready to start again," Wright
said in an e-mail to The Associated Press from aboard the
Development Driller III vessel.
The Deepwater Horizon rig exploded April 20, killing 11 workers
and causing 206 million gallons of oil to spew from BP's well a
mile beneath the surface of the Gulf of Mexico.
A procedure in which mud and cement was pumped in through the
top of the well significantly reduced pressure inside the well.
But the government believes the so-called bottom kill procedure
is necessary to declare the well dead once and for all.
Also Wednesday, National Oceanic and Atmospheric Administration
chief Jane Lubchenco responded to warnings from independent
researchers who insist that the oil spill is a bigger mess than the
government claims and that a lot of crude is lurking deep below the
At the White House on Aug. 4, Lubchenco said that about 74
percent of the oil had been captured, burned, skimmed, evaporated,
dissolved or dispersed. She asserted that the remaining 26 percent
of the oil was on or just below the surface, had washed ashore or
been collected from the shore, or was buried in sand and sediments.
That's not what the scientists from South Florida and Georgia
found. They said that the oil is not gone and it has to be dealt
Lubchenco told reporters Wednesday that she stands by the
conclusions in the government's report.
But, she added, "We know that oil is out there. It is diluted.
Dilute and dispersed does not mean benign."
