Feds Dramatically Increase Oil Spill Estimate, Making BP’s The Worst Oil Accident In History

Email Comments 104 BP’s disastrous oil well explosion sent over 4 million barrels of oil spewing into the Gulf of Mexico, the Coast Guard announced Monday, dramatically increasing the most recent federal estimate.

That’s more than 170 million gallons, and makes it the worst accidental oil spill in history — outpacing the 1979 Ixtoc spill, also in the Gulf of Mexico, which lasted for a year.

A federal scientific task force, finally allowed access to the wellhead just prior to it being capped on July 15, took elaborate pressure readings and other measurements to reach its conclusions.

Federal officials now estimate that 53,000 barrels of oil per day were gushing from the well immediately preceding its closure, and that even more was coming out earlier. The well exploded on April 20, killing 11 workers.

Scientists now estimate that a total of 4.9 million barrels were released from the well, with about 800,000 barrels of that successfully recaptured by BP once the first containment cap was installed.

The Obama administration and BP originally estimated the spill at 5,000 barrels a day, and clung to that figure for weeks despite protestations by scientists and environmental groups, and even after a video clip of the spewing pipe exposed that as a wild underestimate.

It wasn’t until late May that the Interior Department described 12,000 to 19,000 barrels as a “preliminary best estimate” of the flow. That number then increased again two weeks later, to 20,000 to 40,000 barrels a day, and then a few days after that to 35,000 to 65,000 barrels a day.

Up until Monday, “over 2 million barrels” had emerged as a consensus estimate.

The new estimates are from the National Incident Command’s Flow Rate Technical Group, led by United States Geological Survey Director Marcia McNutt, and a team of Department of Energy scientists and engineers.
