Elastic physical seismic modeling

A physical seismic modeling system for studying elastic waves in solid models has been established. Compressional and shear transducers are used to acquire multi-component shot gathers over models of interest. Split shear waves were observed in initial experiments over a layer of phenolic CE, which displays orthorhombic anisotropy. Moveout velocities of P-P and SH-SH reflections from the base of the phenolic layer are offset-dependent and are complex functions of the vertical and horizontal P-wave and SH-wave velocities.
