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






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






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






4. Oil with little or no sulfur






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






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






7. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






11. Structural traps and stratigraphic traps






12. 1 Therm = 100000 Btu






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






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






15. For lubricating motors






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






17. 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.






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






19. Fuel for cars






20. 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.






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






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






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






24. 1 Btu = 2.931x10-4 kWh






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






26. Soot - sulfur oxides - nitrogen oxides - mercury






27. Marine shale - limestone - or oil shale






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






29. A mixture of of hydrocarbons and organic compounds






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






31. Intermediate between hard coal and peat






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






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






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






35. Soft coal - with the highest energy content






36. Energy






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






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






39. Fuel for trucks






40. For heating - cooking - and making plastics






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






42. Hard coal - with the second highest energy content






43. Peat - formed from plants.






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






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






46. Refined natural gas that contains pure methane.






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






48. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






49. 125000 Btu per gallon






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