Timeline of the Deepwater Horizon oil spill (August 2010)
From Wikipedia, the free encyclopedia
Following is a timeline of the Deepwater Horizon oil spill for August 2010 .
August 1–7
- August 1
- Some BP gas stations say they want to revert to the Amoco brand.[1]
- BP exec Doug Suttles says he would eat seafood from the Gulf saying, "There's been a tremendous amount of testing done by NOAA (the National Oceanic and Atmospheric Administration) and the state agencies and the FDA and others. They're not going to open these waters to either sport fishing or commercial fishing if it's not safe to eat the fish...I have a lot of confidence in those agencies and I trust their recommendations and I would eat their food -- the seafood out of the Gulf, and I would feed it to my family."
- August 2
- Flow Rate Technical Group reports that the well initially was dumping 62,000 barrels of oil per day initially after the spill and that it dwindled to 53,000 barrels when it was capped as the well was depleted. This means that 4.9 million barrels were dropped into the Gulf.[2][3][4][5]
- A hydraulic leak delays the start of the static kill process.[6]
- Environmental Protection Agency releases a study of eight dispersants which concludes that Corexit 9500 "is generally no more or less toxic than mixtures with the other available alternatives" and that "dispersant-oil mixtures are generally no more toxic to the aquatic test species than oil alone".[2][7][8][9]
- X Prize Foundation offer $1 million prize for idea that "demonstrates the ability to recover oil on the sea surface at the highest oil recovery rate (ORR) and the highest recovery efficiency"[10][11]
- Pamela Anderson, honorary chairman of People for the Ethical Treatment of Animals, is in New Orleans to draw attention to the transfer of 50 dogs in shelters to Virginia Beach Society for the Prevention of Cruelty to Animals. There'd been an increase in animals encaged in shelters because people who lost their jobs could not afford the upkeep of their pets, according to Anderson. She personally adopted two small dogs and named them Gina Lollobrigida and Brigitte Bardot.[12]
- August 3
- Tropical Storm Colin forms in the Atlantic and is expected to travel up along the United States East Coast and not through the Gulf.[13]
- BP begins pump drilling mud 13.2 pounds per gallon via the top cap at approximately 4 p.m.[14]
- BP bills Anadarko Petroleum $1.2 billion for its share of spill costs.[15]
- Last recorded observation of oil on the sea surface from aerial surveillance <UAC OSAT report https://web.archive.org/web/20110303025448/http://www.restorethegulf.gov/release/2010/12/16/data-analysis-and-findings>
- August 4
- BP reports that the well achieved "static condition" shortly after midnight after 2,300 barrels of drilling mud is said to fill the well.[14][16][17]
- Harry Reid delays a vote on Senate bill which would lift the $75 million cap for economic damages from a spill under after the summer recess.[18]
- NOAA Administrator Jane Lubchenco release the Oil Budget Calculator which says, "it is estimated that burning, skimming and direct recovery from the wellhead removed one quarter (25%) of the oil released from the wellhead. One quarter (25%) of the total oil naturally evaporated or dissolved, and just less than one quarter (24%) was dispersed (either naturally or as a result of operations) as microscopic droplets into Gulf waters. The residual amount — just over one quarter (26%) — is either on or just below the surface as light sheen and weathered tar balls, has washed ashore or been collected from the shore, or is buried in sand and sediments. Oil in the residual and dispersed categories is in the process of being degraded."[19][20]
- August 5
- BP begins pumping cement into the well from the top. Greg McCormack, program director of the Petroleum Extension Service at the University of Texas, Austin explains "When the well is static, it's killed...But if you remove the pressure, it can become unkilled. Once you put cement in it from the bottom, then it can never be unkilled." Plans are continuing to place cement in the bottom starting around August 15.[21]
- Workers file $10 billion suit against BP over a Spring 2010 incident in which 500,000 pounds of pollutants, including benzene were released at the Texas City, Texas refinery that was the site of the 2005 Texas City refinery explosion.[22]
- BP completes cementing of the well from the top at 2:15 p.m. CDT.[23]
- August 6
- Mike Utsler replaces Doug Suttles as BP's lead representative in the Unified Area Command and as chief operating officer for the BP Gulf Coast Restoration Organization, Suttles will return to his job as BP COO.[24]
- Suttles says BP may drill the well again.[25]
