A BP executive says a cap that's been placed atop a blown-out oil well in the Gulf of Mexico has been collecting some oil but he doesn't know how much.
BP PLC's Chief Operating Officer Doug Suttles told NBC's "Today" show Friday that oil has started flowing up the pipe from the cap. But Suttles said it will be later in the day before they know how much is being captured from the nation's worst oil spill.
Robots a mile beneath the Gulf positioned the inverted funnel-like lid over the main pipe on the leaking well Thursday night. Live video footage, though, showed that the oil seemed unimpeded.
To put the cap in place, BP had to slice off the pipe with giant shears, which was risky because it could temporarily increase the flow by as much as 20 percent.
