Washington (CNN) — BP acknowledged Thursday that the gusher of oil pouring from its damaged Gulf of Mexico well is bigger than estimated to date, as new video showed a cloud of crude billowing around its undersea siphon.Company spokesman Mark Proegler said Thursday that the siphon is now drawing about 5,000 barrels (210,000 gallons) a day up to a ship on the surface. That’s as much as government and company officials had estimated the spill was pouring into the Gulf every day for a month. Proegler declined to estimate how much more oil was escaping.BP America Chairman Lamar McKay said Wednesday the figure used by the oil spill response team had a degree of uncertainty built into it. But figures by independent researchers have run up to many times higher: Steve Wereley, a professor of mechanical engineering at Purdue University, told CNN’s “American Morning” that the spill could be as big as 20,000 to 100,000 barrels a day.
