B047 Seismic Attenuation Models for Partially Saturated Media B.B.S.A. Vogelaar* (Delft University of Technology) & D.M.J. Smeulders (Delft University of Technology) SUMMARY Usually wave propagation in the presence of partial fluid saturation is modeled according to the White- Dutta-Odé (WDO) model which is based on the calculation an effective wave modulus of the saturated medium from a boundary value problem. We present here a new model that overcomes some disadvantages in that model by the definition of an effective bulk modulus of the fluid which includes gas bubbles according to the Smeulders-Van Dongen (SvD) model. This paper compares the frequencydependent
