Almost three quarters of the oil from BP’s Deepwater Horizon well has either been cleaned up, recovered or broken down according to a US Goverrnment Report.
The vast majority of the oil from the BP 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. The report marks a key stage for BP and the US Government.
A third (33 percent) of the total amount of oil released in the Deepwater Horizon/BP spill was captured or mitigated by the Unified Command recovery operations, including burning, skimming, chemical dispersion and direct recovery from the wellhead, according to a federal science report released today.
An additional 25 percent of the total oil naturally evaporated or dissolved, and 16 percent was dispersed naturally into microscopic droplets. The residual amount, just over one quarter (26 percent), is either on or just below the surface as residue and weathered tarballs, has washed ashore or been collected from the shore, or is buried in sand and sediments. Dispersed and residual oil remain in the system until they degrade through a number of natural processes. Early indications are that the oil is degrading quickly.
These estimates were derived by the National Oceanic and Atmospheric Administration (NOAA) and the Department of the Interior (DOI), who jointly developed what’s known as an Oil Budget Calculator, to provide measurements and best estimates of what happened to the spilled oil. The calculator is based on 4.9M barrels of oil released into the Gulf, the government’s Flow Rate Technical Group estimate from Monday.
