TRANSCRIPT
UH&CSM Fluid /DHI
Challenges in 2020
• Energy demand: 60% (?) increase
• CO2 emission increase: 60% (?)
• Hydrocarbon will be sustainable
• It is challenge to humanity
• China has to be big part to face the challenge
UH&CSM Fluid /DHI
Technical Challenges
Frontier Target
Unconventional Resources
More Accurate & Efficient
UH&CSM Fluid /DHI
Who will do it• National or company wide effort
• We need team up world wide: – Opening SEG Beijing Office
• Basic and application research
• Who will do it– Consortium research? – Project research?
