On Friday, BP began lowering a newly constructed 98-ton containment dome over two leaks in the Deepwater Horizon well at the seabed. BP is attempting to install the dome to funnel the oil up to a drilling rig.
A senior BP executive on Thursday told reporters at an event in Boston that after a week "we'll have a good idea" whether the dome works. Robert Dudley, BP's executive vice president for the Americas and Asia, also cautioned that such technology was untested at this depth, 5,000 feet below the surface.
Mr. Dudley said BP also was considering installing a "top kill" device, which would send a heavy liquid into the well to reduce the flow of leaking oil.
