BP says “static kill” operation at ruptured U.S. oil well
Obama says long battle in Gulf close to end
New Report: 74% of Oil in BP Deepwater Horizon Oil Spill has been Contained or Mitigated

Wednesday, August 04, 2010

About three-quarters of the oil spilled from the ruptured BP well in the Gulf of Mexico has disappeared, a top U.S. official said Wednesday.

‘The scientists are telling us about 25 percent was not captured or evaporated or taken care of by mother nature,’ said Carol Browner, a top energy adviser to U.S. President Barack Obama, on the ABC network’s Good Morning America program.

‘This is an initial assessment by our scientists in the government and outside the government. We think it’s important to make this available to the public. That’s what we’ll be doing today.’

Browner said the report to be released later on Wednesday was ‘encouraging’ but that more clean-up will be needed.

‘Mother nature will continue to break it down,’ she said.

‘But some of it may come onshore, as weathered tar balls. And those will be cleaned up. They can be cleaned up. And we will make sure they are cleaned up.’

An estimated 4.9 million barrels of oil leaked into the Gulf of Mexico over a period of 87 days after an explosion on a BP-leased offshore rig on April 20.

The leak was capped on July 15, and on Wednesday BP said it succeeded in controlling the pressure in the ruptured well through a procedure called a ‘static kill.’

The New York Times said the report from the National Oceanic and Atmospheric Administration, indicated that fears that a huge underwater glob of oil would surface at some point to tar Gulf beaches looked increasingly unlikely.

‘There’s absolutely no evidence that there’s any significant concentration of oil that’s out there that we haven’t accounted for,’ Jane Lubchenco, head of the agency, was quoted as saying.

Today, a panel of government scientists released a report which said that the vast majority of the oil from the Deepwater Horizon oil spill has either evaporated or been burned, skimmed, recovered from the wellhead or dispersed much of which is in the process of being degraded. A significant amount of this is the direct result of the federal government’s aggressive response to the spill.

The chart below outlines the breakdown of what has happened to the oil released into the Gulf of Mexico since the oil spill began in April:

These interagency findings were generated using a scientific tool called the Oil Budget Calculator, which employs a combination of direct measurements and the best scientific estimates available. The calculator is based on 4.9 million barrels of oil released into the Gulf, the government’s latest estimates of the flow rate from Monday. More than 25 of the best government and independent scientists contributed to or reviewed the calculator and its calculation methods. Scientists from the National Oceanic and Atmospheric Administration (NOAA), the Environmental Protection Agency (EPA) and the Department of Energy (DOE), as well as academic scientists are continuing to work to refine these calculations.

While we welcome the news contained in this report, we continue to be extremely concerned about what this oil spill means for the health of the Gulf ecosystem and the millions of people who depend on the Gulf for their livelihoods and enjoyment. To that end, our response effort will continue until the well is killed, the oil is cleaned up and until all of the people are made whole again.
