Some seismic reflections on 3C-3D and anisotropy

R. James Brown


In this short note I consider some of the features of different 3-D surveys - P-P, S-S and P-SV - that make them more or less advantageous for anisotropy analysis. The implications of survey type, that is, source and receiver polarizations, upon phenomena such as shear-wave splitting and moveout variation with offset and azimuth are considered. There are apparently many benefits to be derived from the 3C-3D survey with a single (P) source type, both in terms of data acquired and of cost.
