BP's chief executive told a British newspaper in May that "the Gulf of Mexico is a very big ocean," and the vast amounts of oil and chemical dispersants dumped into it were small by comparison. After he said that, BP's well leaked for two more months. Hayward's upbeat assessment was cast as one of many gaffes committed on his way to resignation.
Now, 14 days after the well was closed and 100 days after the blowout, U.S. government scientists are working on calculations that could shed some light on Hayward's analysis (even if they can't shed light on why he said it). They are trying to figure out where all the oil went.
