Abstract

For multicomponent seismic data joint processing and interpretation, event registration of C-waves in the P-wave time domain is a critical step, which is one of the “bottlenecks” that limits further application of the multicomponent data. In order to solve this problem, we use the Needleman-Wunsch (NW) algorithm, a nonlinear global optimization method developed for amino acid sequence alignment in proteins, to align C-wave events. The objective function is to maximize the waveform similarity to compensate for the different reflectivities of P-wave and C-wave. Both numerical modeling and field data examples are used to illustrate the methodology and its efficiency and robustness for event registration.
