Two methods are used to extract bitumen: in situ extraction and surface strip mining. The in situ method is used when bitumen is deeper underground. Machines are used to inject high-pressure steam to heat the sands and reduce bitumen viscosity so it can be extracted like conventional oil. The process uses a huge amount of water and natural gas.
