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. Peat - formed from plants.






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






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






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






5. Fuel for cars






6. Fuel for trucks






7. For heating - cooking - and making plastics






8. Hard coal - with the second highest energy content






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






10. Heat - pressure - dearth of oxygen






11. Energy






12. 22% of energy consumed in the U.S. comes from the burning of natural gas.






13. Structural traps and stratigraphic traps






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






15. Refined natural gas that contains pure methane.






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






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






18. 1 Btu = 1055 J






19. Salt or cemented sandstone






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






21. For lubricating motors






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






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






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






25. 1 Therm = 100000 Btu






26. Marine shale - limestone - or oil shale






27. 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.






28. Traps formed by folding or faulting of rock layers






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






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






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






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






33. A mixture of of hydrocarbons and organic compounds






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






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






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






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






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






39. Intermediate between hard coal and peat






40. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






42. Soot - sulfur oxides - nitrogen oxides - mercury






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






44. Soft coal - with the highest energy content






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






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






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






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






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






50. 125000 Btu per gallon
