- Oil
- Formation
- Plant/animal matter buried
- Anaerobic conditions prevent decomposition
- Heat and pressure created liquid
- Extraction
- Flows through permeable rock to collect in porous rock pores
- Pressure forces oil to the surface with drilling
- Primary recovery - using natural pressure (20%)
- Secondary recovery - pumping natural gas/water (40%)
- Tertiary recovery - using solvents, steam or detergent to make oil less viscous (60%)
- Uses
- Liquid vehicle fuels
- Polymerisation
- Characteristics
- High energy density
- Finite resource
- Most industries reliant on imported oil
- The higher the level of technology, the higher the yield
- Contributes to climate change and oil pollution
- Formation
