Well killed by heavy mud

The BP well that spewed millions of gallons of oil into the Gulf of Mexico has been killed by heavy drilling mud. BP made the announcement early Wednesday. Technicians will determine, perhaps as soon as today, whether to follow the mud with cement that would seal the well permanently.
