US scientists announced on Wednesday that approximately 74 percent of the oil spilled from the BP disaster in the Gulf of Mexico has been removed, leaving 26 percent remaining in various forms such as sheen, tarballs, buried sediment, or washed ashore. According to the report "BP Deepwater Horizon Oil Budget: What Happened to the Oil?", a quarter of the oil was removed through burning, skimming, and direct recovery efforts, while another 25 percent evaporated or dissolved naturally and 24 percent was dispersed into small droplets. The remaining oil is either on or just beneath the water's surface, washed ashore, or buried in sediments. The Unified Command, which includes government and private entities, has dealt with 33 percent of the spilled oil. The report discovered that 17 percent of the oil was collected directly from the wellhead, while 5 percent was burned, 3 percent was skimmed, and 8 percent was dispersed using chemicals. The remaining 74 percent was removed through natural processes. Carol Browner, energy and climate change adviser to President Barack Obama, stated on ABC's "Good Morning America" show that the majority of the oil seems to have disappeared, according to the initial assessment by scientists. She also expressed that this is seen as a significant milestone.
