Oil extraction problems

Oil extraction problems
Key Info
  • Oil extraction problems
  • Duration: 04:15
  • A simple oil rig and oil reserve is engineered by Jem Stansfield from the BBC One series 'Bang Goes the Theory'. Forces are described in detail, as is the potential problems associated with an oil blow out. He explains about the importance of mud/ clay in the extraction of oil. The density of the oil matches the density of the clay, known as hydrostatic balance, thus preventing a blow out of the oil. Sadly, this process is not always successful and leads to accidents and oil spills around the world.First broadcast on BBC One on 'Bang Goes the Theory' in September 2010.

Ideas for use in class
  • Could be used to help explain the importance of balanced forces during oil extraction. A simple engineering demonstration and the potential environmental impact of an oil spill. This clip accompanies a BBC Teachers' Pack to support Series 3 and 4 of 'Bang Goes The Theory'. The pack can be downloaded from
