Because it does not flow like water or light crude, it cannot be moved through pipelines in its raw form without dilution or heating, which adds complexity and cost to its journey from the mine to the refinery. Mining operations separate the bitumen from the sand and clay using water and chemical processes.
Bitumen Oil Sands Refining Process: From Raw Extraction to Flowable Dilbit
This heavy density, measured in API gravity, presents a fundamental challenge for transport and refining. On the global stage, oil sands provide a reliable, albeit controversial, source of heavy crude oil that helps meet worldwide demand for diesel, jet fuel, and other essential products, influencing energy security and trade relationships across continents.
In-situ production often involves blending the raw bitumen with a lighter hydrocarbon diluent, such as natural gas condensate, to create a flowable mixture called dilbit, which can then be transported via pipeline to a refinery for further upgrading. Other substantial but less developed deposits exist in Venezuela, the United States, and Kazakhstan, presenting a diverse but geographically concentrated global resource base.

Environmental Considerations and Technological Innovation Extraction and processing of bitumen from oil sands carry environmental considerations that are actively managed and debated. The industry supports hundreds of thousands of jobs directly and indirectly, contributing significantly to government revenues through taxes and royalties.
