Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Fuel for jets and tractors






2. A layer of cap rock that confines the oil and gas - must be impermeable.






3. Remaining oil is made more fluid so as to bring it up more easily. Brings up another 5-15% of the supply - but is much more costly.






4. For lubricating motors






5. Formed by changes in rock type or sedimentary features that create a space where hydrocarbons are confined by impermeable layers






6. Traps formed by folding or faulting of rock layers






7. The quantity of oil (or other energy resource) that exists and can be recovered under current operating and economic conditions.






8. An emergency supply of crude oil created by the US government following the oil embargo of 1973-1974. Contains more than 700 million barrels.






9. Cubic feet - volume - used when gas is at normal temperature and pressure - Dollars per volume in cubic feet - price






10. Phytoplankton and zooplankton that accumulated in marine sediments beginning 300 million years ago






11. A type of sedimentary rock that - when heated - releases hydrocarbons.






12. Coal is converted to a gas - making it easier to remove impurities.






13. 1 Btu = 1055 J






14. 125000 Btu per gallon






15. Natural gas that has been cooled to a liquid to store and transport.






16. Under layers of sedimentary rock like limestone and shale - and over sandstone.






17. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






18. The ratio of the energy return to the energy invested.






19. Marine shale - limestone - or oil shale






20. Fraction of California's total energy requirements provided by natural gas

21. Hard coal - with the second highest energy content






22. Soft coal - with the highest energy content






23. Raw material in the production of pain and fertilizer - steel - glass - paper - and other products.






24. Natural gas that exists in other forms - making it more difficult to extract.






25. Natural gas that has been compressed and stored at very high pressure in strong containers.






26. Peat - formed from plants.






27. The process of drilling for oil and pumping it out. Accounts for 5-15% of the supply.






28. Generate electricity - produce steel - plastics - synthetic fibers - fertilizers - and medicines






29. Soot - sulfur oxides - nitrogen oxides - mercury






30. Fuel for cars






31. Source rock under a reservoir bed - under a trap.






32. Length of time global natural gas supply is expected to last.






33. Length of time US coal reserves are expected to last...






34. Energy






35. 1 Therm = 100000 Btu






36. Crude oil that contains a mixture of hydrocarbons that are relatively less dense






37. Refined natural gas that contains pure methane.






38. Structural traps and stratigraphic traps






39. An arch of stratified rock - an important geological feature that may be associated with reserves of oil - a type of structural trap.






40. For heating - cooking - and making plastics






41. Intermediate between hard coal and peat






42. 1 Btu = 2.931x10-4 kWh






43. Crude oil that contains a mixture of hydrocarbons that are relatively dense






44. A mixture of of hydrocarbons and organic compounds






45. Water or gas is injected into the reservoir to increase the pressure - bringing the oil to the surface. Begins when the oil no longer rises naturally to the surface. Accounts for 15-45% of the supply.






46. Reserves that are not as well known or characterized as proved reserves






47. Methane produced by the action of microorganisms on waste in landfills






48. An industrial fuel - also used to make petroleum products






49. Oil with little or no sulfur






50. A layer of relatively porous and permeable rock in which the oil and gas coming up from the source rock can reside.
