As I noted Tuesday, there is growing evidence that BP's oil well - technically called the "well casing" or "well bore" - has suffered damage beneath the level of the sea floor.
The evidence is growing stronger and stronger that there is substantial damage beneath the sea floor. Indeed, it appears that BP officials themselves have admitted to such damage. This has enormous impacts on both the amount of oil leaking into the Gulf, and the prospects for quickly stopping the leak this summer.
On May 31st, the Washington Post noted:Sources at two companies involved with the well said that BP also discovered new damage inside the well below the seafloor and that, as a result, some of the drilling mud that was successfully forced into the well was going off to the side into rock formations.On June 2nd, Bloomberg pointed out:
"We discovered things that were broken in the sub-surface," said a BP official who spoke on the condition of anonymity. He said that mud was making it "out to the side, into the formation."
Plugging the well is another challenge even after BP successfully intersects it, Robert Bea, a University of California Berkeley engineering professor, said. BP has said it believes the well bore to be damaged, which could hamper efforts to fill it with mud and set a concrete plug, Bea said.Bea is an expert in offshore drilling and a high-level governmental adviser concerning disasters.
