Reliable estimation of seismic anisotropy requires seismic data with wide reflection angles. Fixed cable length limits these angles and hinders standard methods of anisotropic velocity analysis, especially within deeper intervals. We show how these limitations can be mitigated by using reflections from dipping horizons and fault planes (multi directional residual curvature analysis ? MDRCA). Real data examples show how additional information obtained by MDRCA can improve the quality of depth processing results.
