1. Use of Geologic Maps and Structural Geology to locate an oil well

2. Oil Exploration Identify rock types and dip direction Transfer data to map Drawing geological map Identify geologic structures and draw cross section

3. Study Subsurface by Seismic Reflection W. W. Norton

4. Test Borehole Oil!

5. Formation of Oil Page 62 W. W. Norton Source rock is impermeable organic rich shale

6. Oil is buoyant and moves through permeable reservoir rock W. W. Norton

7. Oil rises until blocked by seal rock which is impermeable W. W. Norton

8. Oil reserves have to be trapped so the oil cannot escape. In the trap are Source rock Reservoir rock Seal rock Cross Section of Dome Oil Trap Page 63
