Just two days after the rig explosion, Mix emailed a projection to a supervisor estimating the runaway well could be leaking from 62,000 barrels per day to 146,000 barrels per day. Two days later, BP executives told the Coast Guard their best estimate for the leak was 1,000 barrels per day. A federal scientific group concluded after the well was capped that the flow was 62,000 barrels per day at the beginning of the disaster.
