Presentation transcript:

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

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

Study Subsurface by Seismic Reflection W. W. Norton

Test Borehole Oil!

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

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

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

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
