Everyday Science: Oil Shale Quiz
by Staff
Oil drilling, though difficult, is pretty simple when compared to oil shale extraction. Getting oil shale, solidified oil trapped inside rock, to the surface is currently more expensive and environmentally harmful than conventional drilling. How much do you know about this potential fuel source trapped beneath the Earth's crust?

After oil shale is excavated, extreme heat liquefies the trapped fuel and separates it from rock in a process called:

  • surface extraction
  • pyrolysis
  • retorsion

What's the name of the fossil fuel trapped inside the rock?

  • kerogen
  • oil shale
  • crude oil

How much water does it take to produce a barrel of oil shale liquid?

  • one barrel
  • two barrels
  • five barrels

About how much rock is left behind from each barrel of shale-derived oil?

  • 0.5 tons (0.4 metric tons)
  • 1.5 tons (1.36 metric tons)
  • 3 tons (2.7 metric tons)

Which of the following issues does the Shell Company's improved oil shale refining process not eliminate?

  • mining
  • rock extraction
  • expensive costs

What's the name of the world's largest oil shale reserve?

  • Green River Formation
  • Australian Tertiary Deposit
  • El-Lajjun Deposit

About how much crude oil can Green River Formation's reserves produce?

  • 1 to 1.3 million barrels
  • 2 to 2.5 billion barrels
  • 1.5 to 1.8 trillion barrels

How much oil does the United States consume daily?

  • 26 million barrels
  • 21 million barrels
  • 19 million barrels

At what temperatures will kerogen liquefy?

  • between 500 and 600 degrees Fahrenheit (200 and 316 degrees Celsius)
  • between 650 and 700 degrees Fahrenheit (343 and 371 degrees Celsius)
  • between 750 and 800 degrees Fahrenheit (399 and 427 degrees Celsius)

What term is used to describe the point when available conventional oil reaches a decline?

  • oil apocalypse
  • peak oil
  • oil recession
