COVINGTON, La. (AP) — BP spokesman John Curry says the company does not know how much oil is contained the vast reservoir nearly three miles beneath the seafloor.

Curry said Sunday that the company didn't have time to properly analyze how much was in the discovery well. He says if the oil rig had not exploded, BP PLC ultimately would have drilled another well to complete that analysis.

Curry says the uncertainty over how much oil is in the reservoir does not change BP's response. The company has been trying to stop the gusher for nearly six weeks and the realization that oil could be flowing into the Gulf for months is setting in for Gulf coast residents.
