  1. HGS Petroleum Exploration Methods What Geologists and Geophysicists do to find oil and gas Cerro Azul #4 blow-out, Veracruz, Mexico February 1916 Houston Geological Society Academic Liaison Committee

  2. HGS Petroleum Exploration Methods Part I: What is petroleum and where is it found? Houston Geological Society Academic Liaison Committee

  3. What is Petroleum? A natural, yellow-to-black, flammable, liquid hydrocarbon found beneath the earth’s surface Houston Geological Society Academic Liaison Committee

  4. The Origin of Petroleum Organic-rich Source Rock Thermally Matured Organic Matter Oil Houston Geological Society Academic Liaison Committee

  5. Kerogen Types TOC 2.12 WT.% TOC .38 WT.% Houston Geological Society Academic Liaison Committee

  6. Types of Petroleum Oil and gas are formed by the thermal cracking of organic compounds buried in fine-grained rocks Algae = Hydrogen rich = Oil-prone Wood = Hydrogen poor = Gas-prone Houston Geological Society Academic Liaison Committee

  7. What is Petroleum? What is it used for? Houston Geological Society Academic Liaison Committee

  8. What is Petroleum? More Than 3,000 Products • Detergents - Cosmetics • Fertilizers - Weed Killers • Medicine - Antiseptics - Anesthetics • Plastics - Synthetic Fibers • Synthetic Rubber • Rust Preventatives • Liquid Petroleum Gas Houston Geological Society Academic Liaison Committee

  9. Petroleum—Where is it found? Basins are containers for sediment Earth’s basins contain sediment/rocks, air, or water Houston Geological Society Academic Liaison Committee

  10. Basins:Forces that shape the earth’s crust Plate Tectonics Houston Geological Society Academic Liaison Committee

  11. Basins:Forces that shape the earth’s crust Basins form in response to subsidence caused by movement of the crust and grow due tectonic “loading” Houston Geological Society Academic Liaison Committee

  12. Basins:Forces that shape the earth’s crust Basins form in response to subsidence of the crust and grow due “loading” of sediment deposited in them Houston Geological Society Academic Liaison Committee

  13. Basins:Sedimentary rocks accumulate in basins Basins may contain petroleum source rocks, reservoir rocks and seal rocks Houston Geological Society Academic Liaison Committee
