HOUSTON (Reuters) - BP pumped heavy drilling mud into its blown-out Gulf of Mexico well on Tuesday in a "static kill" operation it hopes will help permanently plug the world's worst accidental marine oil spill.
The operation, aimed at subduing the still unstable deepwater gusher that was provisionally capped in mid-July, is part of a two-pronged strategy that seeks to finally seal the Macondo well later in August through a relief well.
