The book addresses the theoretical foundations and practical application of multi-focusing methods in seismic data processing. The basic idea of these methods is to improve the signal-to-noise ratio by coherently stacking seismic traces along traveltime-field functions that correspond to the local kinematics of the wavefield. The book combines mathematical descriptions of the methods, principles of their algorithmic implementation, and results of processing real 2D and 3D seismic data.
Traditional methods such as Multifocusing (MF) and Common Reflection Surface (CRS) are considered. These methods are based on parametric approximation of the local traveltime field and estimation of the corresponding parameters by maximizing coherence. Different approaches to traveltime-field parameterization are presented: in terms of its derivatives, the characteristics of the fundamental wavefronts, and the parameters of an effective model with a curved reflector. On this basis, the Taylor Multi-Fo
