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. Energy






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






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






5. For heating - cooking - and making plastics






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






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






8. Oil with little or no sulfur






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






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






11. Peat - formed from plants.






12. Fuel for cars






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






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






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






16. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






17. Fuel for trucks






18. Hard coal - with the second highest energy content






19. Refined natural gas that contains pure methane.






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






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






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






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


24. Intermediate between hard coal and peat






25. A mixture of of hydrocarbons and organic compounds






26. 1 Therm = 100000 Btu






27. 1 Btu = 1055 J






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






29. Salt or cemented sandstone






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






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






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






33. For lubricating motors






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






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






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






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






38. Traps formed by folding or faulting of rock layers






39. Structural traps and stratigraphic traps






40. 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.






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






42. 22% of energy consumed in the U.S. comes from the burning of natural gas.






43. 1 Btu = 2.931x10-4 kWh






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






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






46. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






50. 125000 Btu per gallon
