1. LAB 5: Exploring for Petroleum Key Q: How is petroleum found?

2. Formation of petroleum and natural gas Forms from marine plants & animals that die-sink-begin to decay-become buried. If temperature conditions are right oil or natural gas will form, and can collect underground in areas called reservoirs.

3. Geology of Petroleum Deposits SRS Source, Reservoir, Seal

4. Geology of Petroleum Deposits Three conditions must be present for oil & natural gas reservoirs to form: SRS: Source, Reservoir, Seal –Source rock: shale rich in organic matter buried deep enough for it to turn into oil; Source of the oil –Reservoir: porous sedimentary rock (usually limestone or sandstone) that the oil can flow through & collect in. –Seal: dense rock that stops the oil from rising up to the surface.

5. Methods of Exploration Geologists map the rocks & project down –Looking for SRS

6. Methods of Exploration Seismic exploration –Create a small explosion and study how density difference cause waves to refract & reflect GEOPHONES Electronic receivers that pick up refracted vibrations in rock or other solid material (use differences in density)

7. Methods of Exploration Drill test wells Method is very Expensive $$$$$

8. How is oil found and made into everyday things??
