The Story of Petroleum
Gas – C1-C4 Liquid – C5-C15 Solid – above C15 Chemical composition of OilHydrocarbons
Natural “traps” keep oil and gas from oozing out at the surface
How to find oil: Source rock, reservoir rock, structural traps
Organic rich shale Late Cretaceous (90 Ma) Late Jurassic (150 Ma) Oil window Thermal history 60-120oC 2000-4500 meter Source Rock
Reservoir Rock • Porosity and permeability • Sandstone and limestone
How to find oil • Surface exploration • Subsurface exploration • Seismic reflection • Drilling
