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






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






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






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






5. For lubricating motors






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






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






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






9. 22% of energy consumed in the U.S. comes from the burning of natural gas.






10. Salt or cemented sandstone






11. Energy






12. Fuel for trucks






13. Marine shale - limestone - or oil shale






14. Fuel for jets and tractors






15. 125000 Btu per gallon






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






17. Fuel for cars






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






19. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






21. 1 Btu = 2.931x10-4 kWh






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






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






24. Peat - formed from plants.






25. Structural traps and stratigraphic traps






26. 1 Therm = 100000 Btu






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






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






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






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






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






32. Refined natural gas that contains pure methane.






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






34. Traps formed by folding or faulting of rock layers






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






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






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






38. Intermediate between hard coal and peat






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






40. 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.






41. 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.






42. 1 Btu = 1055 J






43. Soft coal - with the highest energy content






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






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






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






47. Hard coal - with the second highest energy content






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






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






50. Oil with little or no sulfur
