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






2. Intermediate between hard coal and peat






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






4. A mixture of of hydrocarbons and organic compounds






5. 1 Btu = 2.931x10-4 kWh






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






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






8. 125000 Btu per gallon






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






10. Fuel for jets and tractors






11. Fuel for trucks






12. Heat - pressure - dearth of oxygen






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






14. Marine shale - limestone - or oil shale






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






16. For lubricating motors






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






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






19. Hard coal - with the second highest energy content






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






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






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






23. Fuel for cars






24. For heating - cooking - and making plastics






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






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






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






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






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






30. Refined natural gas that contains pure methane.






31. 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.






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






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






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






35. Structural traps and stratigraphic traps






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






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






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






39. 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.






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






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






42. Traps formed by folding or faulting of rock layers






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






44. Energy






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






46. 1 Therm = 100000 Btu






47. Soft coal - with the highest energy content






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






49. Salt or cemented sandstone






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