HOUSTON (Reuters) - An approaching storm in the Gulf of Mexico will delay BP Plc's work on a relief well, the final step in permanently killing the source of the world's worst offshore oil spill, by two to three days, the top U.S. spill official said on Tuesday.
BP suspended work on a relief well aiming to bore into its blown-out Macondo well after the National Hurricane Center said the system had a 70 percent chance of becoming a tropical depression in the next two days as it moves toward the Louisiana coast.
