BP Completes Relief Well, Now on to ‘Bottom Kill’


BP has finally finished work on the relief well that will permanently seal the Macando oil well that was at the heart of the disaster in the Gulf. The relief well starts about 100 feet from the original well and sensors detect that the two have connected about 18,000 feet below the surface. The next step in permanently sealing the Macando well is “bottom kill,” where heavy mud and cement will be pumped in via the relief well. Government estimates say 4.9 million barrels, or 206 million gallons of oil spilled into the Gulf, 800,000 barrels of which was caught by surface ships. [CNN]
