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






2. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






3. 125000 Btu per gallon






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






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






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






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






8. 1 Therm = 100000 Btu






9. Refined natural gas that contains pure methane.






10. Hard coal - with the second highest energy content






11. Marine shale - limestone - or oil shale






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






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






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






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






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






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






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






20. Structural traps and stratigraphic traps






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






22. Salt or cemented sandstone






23. Heat - pressure - dearth of oxygen






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






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






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






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






28. Fuel for cars






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






30. Intermediate between hard coal and peat






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






32. For heating - cooking - and making plastics






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






34. Fuel for trucks






35. 1 Btu = 1055 J






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






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






38. For lubricating motors






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






40. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






44. Fuel for jets and tractors






45. Peat - formed from plants.






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






47. A mixture of of hydrocarbons and organic compounds






48. Traps formed by folding or faulting of rock layers






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






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