BP Relief Well Could Be Completed Thursday

The relief well could be completed sometime Thursday at the site of the largest oil spill in the nation's history.

The broken well that caused the spill in the Gulf of Mexico could finally be sealed for good by Sunday.

It's been capped since mid-July.

Now, the Obama administration is planning to head off any other BP like disaster.

The Interior Department ordered oil and gas companies in the Gulf to plug or dismantle abandoned wells and platforms.
