BP prepares to permanently plug Gulf of Mexico oil spill
BP are undertaking tests ahead of a procedure to permanently seal the Gulf of Mexico leak, Admiral Thad Allen has said.
Mr Allen, the US official in charge of the spill response, said that the next stage of the operation is to perform a "static kill", which will see heavy drilling fluid known as "mud" used to force any remaining oil back into the reservoir.
A decision will then be made on whether the well can be immediately sealed with cement.
