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






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






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






4. Soft coal - with the highest energy content






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






6. 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.






7. Intermediate between hard coal and peat






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






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






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






11. Traps formed by folding or faulting of rock layers






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






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






14. For heating - cooking - and making plastics






15. Fraction of California's total energy requirements provided by natural gas


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






17. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






18. Soot - sulfur oxides - nitrogen oxides - mercury






19. For lubricating motors






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






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






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






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






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






25. A mixture of of hydrocarbons and organic compounds






26. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






28. Structural traps and stratigraphic traps






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






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






31. 1 Therm = 100000 Btu






32. 1 Btu = 1055 J






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






34. Heat - pressure - dearth of oxygen






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






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






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






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






39. Fuel for trucks






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






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






42. Hard coal - with the second highest energy content






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






44. Fuel for jets and tractors






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






46. 125000 Btu per gallon






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






48. Refined natural gas that contains pure methane.






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






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