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
Technical Challenges Frontier Target Unconventional Resources More Accurate & Efficient
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?
