.... Increased variability and anisotropy with a tilted symmetry axis (TTI) are now handled. We show that strong contrasts in elastic properties have a dramatic effect on seismic upscaling regardless of anisotropy. In particular, the low- frequency upscaling method (Stovas et al., 2013) developed for isotropic...
