BP is running tests and expected to decide shortly if it will go ahead with an effort to choke off its oil gusher by force-feeding it heavy drilling mud and cement. “Top kill’ is an operation in which heavy mud and cement would be shot into the blown-out well to plug it up.
The oil company BP says it should become clear within hours whether its efforts to seal the leak in the Gulf of Mexico have been successful. Engineers are carring out so-called ‘top kill’ operation which is set to block a breached oil well with mud, which will eventually be topped with cement. The chances of the procedure working, are estimated at 60 to 70 per cent.
