  1. 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

  2. Technical Challenges Frontier Target Unconventional Resources More Accurate & Efficient

  3. 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?

  4. Fluids/DHI Consortium • Start 1995- now (13 years) • Sponsors (24) Anadarko, BG, BHP, BP, CGGVeritas, Chevron, CNOOC, ConocoPhillips, Devon, Encana, Eni, ExxonMobil, Fugro-Jason, JOGMEC, Nexen, Paradigm, Petrobras, Petrochina, Rock Solid images, RWE, Shell, SLB, StatoilHydro, Total

  5. Seismic Rock Physics- Fluids/DHI Consortium Ceremony of Opining SEG Beijing Office April 3, 2008 Dr. De-hua Han (UH), Dr. M. Batzle (CSM) Manika Prasad (CSM)

  6. Wiggles Rock & Fluid“Local Calibration” • Green Canyon, GOM • Plio-Pleistocene • Target TVD 11800ft, OB 4100ft King Kong vs. Lisa Anne Gas Fizz (O’Brien, 2004)

  7. Seismic Rock Physics Rock and fluid Properties & models Rock Physics Seismic Attributes Time, Amp., AVO Spectrum Decom. (T, A, F) Deposition, Structure Compact. & cement. Reservoir Geology
