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. The layer of sediment where oil and gas originate.






2. Oil with little or no sulfur






3. 1 Btu = 1055 J






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






5. 1 Therm = 100000 Btu






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






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






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






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






10. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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

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






15. Fuel for jets and tractors






16. Soot - sulfur oxides - nitrogen oxides - mercury






17. Hard coal - with the second highest energy content






18. Intermediate between hard coal and peat






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






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






21. Fuel for trucks






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






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






24. 1 Btu = 2.931x10-4 kWh






25. Salt or cemented sandstone






26. 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.






27. Structural traps and stratigraphic traps






28. 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.






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






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






34. Marine shale - limestone - or oil shale






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






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






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






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






39. For lubricating motors






40. 125000 Btu per gallon






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






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






43. Heat - pressure - dearth of oxygen






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






45. For heating - cooking - and making plastics






46. Soft coal - with the highest energy content






47. Peat - formed from plants.






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






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






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