  1. AP Environmental Science • Mr. Grant • Lesson 92 Coal, Natural Gas, and Oil (Part 2) & Other Fossil Fuels

  2. Objectives: • Define the terms primary extractionand secondary extraction. • Describe the nature and origin of crude oil, and evaluate its extraction, use, and future depletion. • Describe the nature, origin, and potential of alternative fossil fuels.

  3. Define the terms primary extraction and secondary extraction. Primary Extraction Secondary Extraction

  4. Describe the nature and origin of petroleum, and evaluate its extraction, use, and future depletion. • Crude oil is a thick liquid mixture of hydrocarbons formed underground under certain temperature and pressure conditions. • Scientists locate fossil fuel deposits by analyzing subterranean geology. • Oil drilling involves… • Primary extraction & Secondary extraction. • Petroleum-based products are everywhere in our daily lives... • Gasoline, Clothing, Plastics • Components of crude oil are separated in refineries to produce a wide variety of fuel types. • We have already depleted half the world’s oil.

  5. Heat and pressure underground form petroleum

  6. The age of oil began in the mid-19th century

  7. Petroleum geologists infer deposit location and size

  8. Not all oil can be extracted

  9. Typical seismic surveying

  10. We drill to extract oil… primary and secondary oil extraction

  11. Petroleum products have many uses

  12. We may have already depleted half our reserves

  13. We are facing an oil shortage… U.S. oil production has already peaked

  14. Global oil production is peaking

  15. Predicting an exact date for peak oil is hard

  16. Peaking oil production will have consequences

  17. Describe the nature, origin, and potential of alternative fossil fuels. • Oil sands can be mined and processed into synthetic oil. • Oil shale is abundant in the western U.S. • Methane hydrate found on the seafloor could provide a source of methane gas.

  18. Oil sands can be mined and processed

  19. Oil shale is abundant in the U.S. west

  20. Methane hydrate shows potential

  21. These alternative fossil fuels have downsides
