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






2. Marine shale - limestone - or oil shale






3. Intermediate between hard coal and peat






4. Oil with little or no sulfur






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






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






7. Soot - sulfur oxides - nitrogen oxides - mercury






8. Soft coal - with the highest energy content






9. 1 Therm = 100000 Btu






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






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






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






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






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






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






16. Energy






17. Fuel for cars






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






19. Salt or cemented sandstone






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






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






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






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






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






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






26. 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.






27. Peat - formed from plants.






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






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






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






31. 1 Btu = 1055 J






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






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






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






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






36. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






40. Structural traps and stratigraphic traps






41. Refined natural gas that contains pure methane.






42. A mixture of of hydrocarbons and organic compounds






43. 125000 Btu per gallon






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






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






46. 1 Btu = 2.931x10-4 kWh






47. Hard coal - with the second highest energy content






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






49. Heat - pressure - dearth of oxygen






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