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


2. A mixture of of hydrocarbons and organic compounds






3. 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.






4. Structural traps and stratigraphic traps






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






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






7. Natural gas that flows to the surface from an underground reservoir when a well is dug.






8. Fuel for cars






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






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






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






12. Soft coal - with the highest energy content






13. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






16. Sludge (rich in organic matter) that accumulates at the bottom of lakes or oceans






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






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






19. Salt or cemented sandstone






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






21. Oil with little or no sulfur






22. Consist of clay - sand - water and bitumen - a type of oil.






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






24. 125000 Btu per gallon






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






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






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






28. Peat - formed from plants.






29. For lubricating motors






30. Unrefined oil. May appear thick and brown or black - or clear.






31. The layer of sediment where oil and gas originate.






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






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






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






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






36. 1 Btu = 2.931x10-4 kWh






37. For heating - cooking - and making plastics






38. Energy to raise the temperature of 1 lb of water by 1 degree F at 1 atm.






39. Intermediate between hard coal and peat






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






41. Hard coal - with the second highest energy content






42. 1 Btu = 1055 J






43. Traps formed by folding or faulting of rock layers






44. Burns coal at lower temperatures - reducing the production of nitrogen oxides - and making it easier to remove sulfur oxides.






45. Refined natural gas that contains pure methane.






46. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






49. Fuel for trucks






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