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






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






3. 1 Btu = 2.931x10-4 kWh






4. Unrefined mixture of methane - ethane - propane - and butane.






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






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






7. Energy






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






9. Soot - sulfur oxides - nitrogen oxides - mercury






10. Hard coal - with the second highest energy content






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






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






13. Intermediate between hard coal and peat






14. A mixture of of hydrocarbons and organic compounds






15. Reserves that can reasonably be expected to exist based on geological evidence and projections from proved reserves.






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






17. 125000 Btu per gallon






18. A mixture of hydrocarbons found in naturally occurring underground reservoirs






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






20. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






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






25. Peat - formed from plants.






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






27. Traps formed by folding or faulting of rock layers






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






29. Marine shale - limestone - or oil shale






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






31. 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.






32. Heat - pressure - dearth of oxygen






33. Structural traps and stratigraphic traps






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






35. 1 Therm = 100000 Btu






36. Oil with little or no sulfur






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






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






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






40. Fuel for cars






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






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






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






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






45. For heating - cooking - and making plastics






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






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






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






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






50. Refined natural gas that contains pure methane.
