1. SEAM RPSEA Project Michael Fehler SEAM Phase I Project Manager

2. SEAM Phase I Model Construction –Density and P-wave velocities described from rock and reservoir properties Variable-density acoustic simulations –Approximately 65,000 shots

3. SEAM RPSEA Research Partnership to Secure Energy for America SEAM work supported as part of Ultra- deewater Program SEAM will continue to use model developed for Phase I (subsalt)

4. Main Focus Areas Variable-density acoustic simulations with absorbing upper surface CSEM simulations –Michael Frenkel will present Gravity simulations –Neda Bundalo will present Elastic simulations Magnetotelluric simulations

5. Model Development Additional parameters needed –Resistivity (vertical and horizontal) –Shear-wave velocity –Decimated density for gravity All models are derived using rock physics consistent with that used for acoustic model construction –Leads to very low S-velocities near seafloor

6. Models
