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






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






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






5. 1 Btu = 1055 J






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






7. 125000 Btu per gallon






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






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






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






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






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






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






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






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






16. Heat - pressure - dearth of oxygen






17. 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.






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






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






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






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






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






23. 1 Btu = 2.931x10-4 kWh






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






25. Intermediate between hard coal and peat






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






27. Fuel for cars






28. Fuel for jets and tractors






29. Soft coal - with the highest energy content






30. Structural traps and stratigraphic traps






31. Traps formed by folding or faulting of rock layers






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. Refined natural gas that contains pure methane.






34. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






37. For lubricating motors






38. Marine shale - limestone - or oil shale






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






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






41. 1 Therm = 100000 Btu






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






43. Energy






44. Oil with little or no sulfur






45. A mixture of of hydrocarbons and organic compounds






46. Salt or cemented sandstone






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






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






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






50. Fuel for trucks
