  1. The Association for the Study of Peak Oil Presentation on Oil Depletion Part 1.

  2. Contents Part 1. Introduction Part 2. How much oil has been found Part 3. How much is yet-to-find Part 4. Modelling depletion Part 5. Denial Part 6. Myths Part 7. Gas and Non-Conventional oil & gas Part 8. Conclusions

  3. Part 1. Introduction & Geological Background

  4. Introduction • Man’s growing energy demands • Supply of oil depends on • Endowment in Nature • Rates of extraction • Economic and political factors • Great advances in petroleum geology improve knowledge • Need for basic geological understanding

  5. The Geological Origins of Oil • A few brief epochs of extreme global warming gave the bulk of the world’s oil • Algal blooms gave organic matter, which was locally preserved in stagnant troughs • It was converted to oil and gas on burial • The processes are well understood.

  6. North SeaOil GeneratingTrends-Where oil is and where it is not

  7. Geology of an Oilfield Gas Oil Water Sandstone Reservoir

  8. What a Reservoir looks like OIL Oil fills the pore-space between the grains of sand, which are often coated in a film of water. It has to flow through these constrictions.

  9. Amazing Seismic Resolution

  10. Conclusion • Knowledge of petroleum geology has advanced greatly • The world has been intensively explored • The more promising areas were investigated first • The larger fields were also found first, being too large to miss • The record of the past points to declining future discovery
