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.

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






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






13. Traps formed by folding or faulting of rock layers

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






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






21. Fuel for trucks






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






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






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






25. 125000 Btu per gallon






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






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






28. Fuel for cars






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






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






31. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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

35. Salt or cemented sandstone






36. 1 Btu = 1055 J






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






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






39. 1 Therm = 100000 Btu






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






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






42. Heat - pressure - dearth of oxygen






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






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






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






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






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






48. Soft coal - with the highest energy content






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






50. Refined natural gas that contains pure methane.
