Multicomponent seismic data allow geologic sequences to be defined with both P-waves and S-waves. These two distinct types of body waves provide different options for defining stratigraphy and facies within stratigraphic intervals. Either wave (P or S) can propagate as fast and slow modes in anisotropic media, but the division into fast and slow modes is much more pronounced for S-waves than it is for P-waves. The interpretation of fast-S and slow-S modes provides invaluable information about azimuth-based rock anisotropy such as aligned fractures, fracture density, and orientations of maximum horizontal stress. By combining P and S data into a...
