BP CEO Tony Hayward told Britain's The Guardian newspaper that the spill was small in proportion to the Gulf.
"The Gulf of Mexico is a very big ocean. The amount of volume of oil and dispersant we are putting into it is tiny in relation to the total water volume," Hayward said.
The National Oceanic and Atmospheric
Administration and BP have estimated that about 5,000 barrels of
petroleum have been pouring into the Gulf each day. But an
exclusive analysis of seafloor video conducted for NPR shows the
leak could be 10 times greater than the official figure.
