BP takes key step in Gulf well 'static kill'

BP pumped cement into its blown-out oil well in the Gulf of Mexico yesterday, hoping to start sealing it for good a day after it forced a slow torrent of heavy mud down the broken wellhead and pushed the crude back to its underground source.
The next step in the so-called "static kill" was another bright spot as the tide appeared to be turning in the months-long battle to contain the oil, with a federal report this week indicating that only about a quarter of the spilled crude remains in the Gulf and is degrading quickly.
Even so, Joey Yerkes, a fisherman in Destin, Florida, said he and other boaters, swimmers and scuba divers continue to find oil and tar balls in areas that have been declared clear.
"The end to the leak is good news, but the damage has been done," Yerkes said.
It could take hours to pump enough fresh cement to fill the well and hours more for it to dry, engineers said. But BP said it decided to begin after testing concluded that it would not do more damage to the ruptured well.
If the mud plug in the blown-out well is successfully augmented with the cement, the next step involves a 5,500-meter relief well that intersects with the old well just above the vast undersea reservoir that had been losing oil freely since the Deepwater Horizon rig exploded off Louisiana on April 20, killing 11 workers.
The hope has been to pump mud and possibly cement down the relief well after its completion later this month, supplementing the work in this week's so-called "static kill" and stopping up the blown-out well from the bottom.
