Who and What are the Oil Sands and Syncrude?
Syncrude here and how
• Largest oil sands producer in the world
• Largest single source of oil in Canada
• Major employer
• Top researcher
• Multi-billion dollar, triple bottom line business
The Canadian Oil Sands are a rich and vast resource• 1.7 trillion barrels in-place
• 300+ billion barrels recoverable
• More than 30% of Canada’s oil production is from the oil sands
• Slated to increase to 50% by 2020

History of CFD at Syncrude
• 1984-1990– Simple 2-D single phase projects contracted out
• 1990 - 2000– Obtained first commercial code (Flow3D from AEA)– Ran two Unix computers– 3-D multiphase transient problems– Primarily used external contractors– Mostly exploring CFD capability – not integrated into research
projects• 2000 – Present
– Larger and more complicated 3-D multiphase transient problems– Done in-house as well as through external consultants– Integrated into research projects to compliment experimental work
