oil flow rate
From yesterday’s Washington Post:
BP's well was gushing faster than expected, government experts said. The latest estimate pegs original "flow rate" at 62,000 barrels a day (2.6 million gallons), higher than the last estimate of 35,000 to 60,000 barrels. As the reservoir was depleted, the rate was reduced to 53,000 barrels a day. They calculated the total oil coming from the blown-out well at 4.9 million barrels, more than 18 times the amount of oil that was spilled during the Exxon Valdez disaster.
From yesterday’s New York Times, which confirmed that the BP spill is by far the world’s largest accidental release of oil into the ocean:
“We’ve never had a spill of this magnitude in the deep ocean,” said Ian R. MacDonald, a professor of oceanography at Florida State University.
“These things reverberate through the ecosystem,” he said. “It is an ecological echo chamber, and I think we’ll be hearing the echoes of this, ecologically, for the rest of my life.”
At this point, we all know that BP’s 5,000 barrel-a-day estimate is laughable, as are their claims that they can't measure the rate that the oil is gushing into the Gulf.
Over the weekend, four scientists, Ian MacDonald, John Amos, Timothy Crone and Steve Wereley wrote an op-ed in the New York Times that provides a new estimate of the oil spill’s flow rate.
BP has claimed that it would be impossible to use their video clip of the broken pipe to analyze the rate of oil flow. These scientists have shown that claim to be blatantly false. Using computational methods to analyze the video, the scientists’ estimates showed median values of 60,000 to 75,000 barrels per day spilling into the Gulf.
