Deepwater Horizon Disaster: Gulf Oil Spill Tragedy

  • The well-heads connect to a central manifold up to 100 feet high, controlling the flow of oil and gas from the oil field to the production rig.
  • The rig separates oil and gas before transporting them to shore through pipelines stretching for hundreds of miles along the sea bed.
  • 43,000 miles of pipeline are present across the Gulf of Mexico.
  • Companies search for new oil fields in the Gulf as reserves near shore deplete.
  • Special rigs like the Deepwater Horizon drill exploration wells called wildcats, reaching miles below the sea bed.
  • The Deepwater Horizon is an exploration drilling rig used for initial drilling and production equipment installation.
  • In 2010, the Deepwater Horizon strikes oil 50 miles off the coast of Louisiana in the Macondo area.
  • An explosion and fire on the Deepwater Horizon result in 11 missing workers and the rig sinking after two days of burning.
  • 60,000 barrels of oil per day escape into the Gulf due to the disaster.
  • Engineers design a capping stack to seal the Macondo well, stopping the flow after 87 days and 5 million barrels of oil escaping.
