Relief well drill is only days away from leaking oil pipe, Guardian, July 4, 2010:
BP is poised to plug its leaking well in the Gulf of Mexico. Drilling engineers have only one chance to get it right.
One wrong move as engineers break through the cement and steel pipe of the Macondo well could increase the torrent of oil into the Gulf. In the worst case scenario, it could even trigger a blow-out in the relief well.
"They pretty much have one shot," said Wayne Pennington, the chair of geophysical engineering at Michigan Tech University. "Once they hit it and they try to kill it they really just have that one chance." ...
The intercept could be complicated if it turns out that the oil is flowing around the pipe, between the pipe and the cement of the well bore.
