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






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






3. Oil with little or no sulfur






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






5. Structural traps and stratigraphic traps






6. Refined natural gas that contains pure methane.






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






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






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






10. Salt or cemented sandstone






11. A mixture of of hydrocarbons and organic compounds






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






13. 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.






14. Marine shale - limestone - or oil shale






15. 1 Btu = 1055 J






16. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






17. Peat - formed from plants.






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






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






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






21. Fuel for cars






22. Soot - sulfur oxides - nitrogen oxides - mercury






23. Fuel for trucks






24. Heat - pressure - dearth of oxygen






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






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






27. 125000 Btu per gallon






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






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






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






31. Soft coal - with the highest energy content






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






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






34. Intermediate between hard coal and peat






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






36. 1 Therm = 100000 Btu






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






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






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






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






41. Energy






42. Hard coal - with the second highest energy content






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






44. 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.






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






46. Traps formed by folding or faulting of rock layers






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






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






49. 1 Btu = 2.931x10-4 kWh






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