BP Plc will try to plug an underwater oil leak in the Gulf of Mexico by pumping heavy drilling fluids into a damaged well in the next few days, as the cleanup costs of the monthlong spill accelerate.

As little as 2 per cent of the oil spilling into the Gulf of Mexico may be accounted for by surface slicks, a study of a controlled spill suggests.
