Analysis of an alternative semblance function applied to Finite-Offset Common-Reflection-Surface tomography

Abstract

Estimation of an accurate velocity model is a significant step in seismic processing.Finite-offset commonreflection-surface tomography is a layer-by-layer velocity inversion technique driven by the mean of global optimization. It is also part of a range of techniques known as coherence inversion methods. In this study, we are interested in analyzing this tomography technique considering an alternative semblance as the objective function. Our applications consist of both synthetic and field examples.
