SEAM RPSEA Project

Michael Fehler

SEAM Phase I Project Manager

SEAM Phase I

• Model Construction– Density and P-wave velocities described from

rock and reservoir properties

• Variable-density acoustic simulations– Approximately 65,000 shots

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)

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

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
