(CNN) - Government officials Tuesday increased the estimate of oil flowing into the Gulf to between 35,000 and 60,000 barrels (1.5 million to 2.5 million) per day, up to 50 percent more than previously estimated.
The government's previous estimate, issued last week, was 20,000 to 40,000 barrels per day. The change was "based on updated information and scientific assessments," and was reached by Secretary of Energy Steven Chu, Secretary of the Interior Ken Salazar, and Chair of the National Incident Command's Flow Rate Technical Group Marcia McNutt, the Deepwater Horizon Incident Joint Information Center said.
"The improved estimate is based on more and better data that is now available and that helps increase the scientific confidence in the accuracy of the estimate," it said.
